Clinical Validation of Non-invasive Simulation-Based Determination of Vascular Impedance, Wave Intensity, and Hydraulic Work in Patients Undergoing Transcatheter Aortic Valve Replacement.

The impact of Aortic Stenosis (AS) on the left ventricle (LV) extends beyond the influence of the pressure drop across the stenotic valve, but also includes the additional serial afterload imposed by the vascular system. Aortic input impedance is the gold standard for comprehensively studying the contribution of the vascular system to total myocardial afterload, but in the past measurement has been challenging arising from the need for invasive catheterization or specialized equipment to precisely record time-resolved blood pressure and flow signals. The goal of this work was to develop and validate a novel simulation-based method for determining aortic input impedance using only clinically available echocardiographic data and a simple blood pressure measurement. A simulation-based method to determine vascular impedance was developed using echocardiographic data and a brachial blood pressure measurement. Simulation-based impedance was compared to impedance calculated from echocardiographic flow data and pressure data from a non-invasive central pressure measurement device. In validation analysis comparing patient-specific simulation-based vascular impedance to non-invasively measured impedance, correlation between methods across a range of vascular parameters varied between R2=0.40 and 0.99. A tendency was seen toward underestimation of pressure waveforms in point-by-point comparison of measured and simulated waveforms with an overall mean difference of 4.01mmHg. Requiring only non-invasive clinical data that are widely available, simulation-based vascular impedance has the potential to allow for easier, more widespread, and larger-scale investigation of the effect of vascular impedance on total LV afterload.

Aplicación de redes neuronales artificiales a la modelación de lluvia-escorrentía en la cuenca del río Chancay Lambayeque

Between the months of December to April, regions of northern Peru, including Lambayeque, are affected by maximum extreme events, wreaking havoc on homes, flooding crop fields, collapsing hydraulic works, and the most irreparable loss of human lives. In this line, the objective of this research was to apply Artificial Neural Networks to rain-runoff modeling in a basin in northern Peru, namely, the Chancay Lambayeque river basin belonging to the Pacific slope. For this purpose, records of precipitation and flows of 30 years (hydrological normal) were collected from 12 hydrometeorological stations belonging to the basin and neighboring it. Thus, applying a model of Long and Short Term Memory Networks (LSTM) we proceeded to model the rain, seeking to follow the behavior of the flows observed in the Racarrumi hydrometric station, with 80 % of the information the model was trained and with 20 % it was validated. In short, it was obtained that in the modeling validation stage, the Nash coefficient was 0.93, corresponding to the qualifier "very good".

Old Data and New Investigations The Urartian and Orontid Fortress of Körzüt in Muradiye Plain, Turkey

This article presents an important archaeological site located on the north-eastern shore of Lake Van, Turkey. The site was one of the first to be associated with the kingdom of Urartu, thanks to the grandeur of its characteristic architecture and the pottery visible on the surface. Körzüt is composed of a vast fortified complex, within which there were certainly a temple, palatine structures, storage rooms, a settlement, and a necropolis. Presumably contemporary hydraulic works have been documented near the site. Körzüt has been the subject of numerous illegal excavations in past and present times, which over the years have brought to light a considerable amount of epigraphic material. This has allowed us to attribute the construction of the complex to King Minua, between the end of the ninth and the beginning of the eighth century BCE. Numerous recent illegal excavations on the site have led to emergency excavations. These investigations have led to the discovery of important remains, which are discussed and contextualised in this paper, together with what was already known in terms of epigraphic and architectural evidence. Furthermore, Körzüt can be added to the list of settlements that were also used in the post-Urartian era in the years in which the Armenian Highlands was dominated by the Orontid dynasty.

Performance Indicators for Improving Irrigation Management in Aegean District

Water is vital for agriculture and its effective use has become imperative. The largest share of freshwater use in the world is in the agricultural sector with a rate of approximately 70%. Therefore, the evaluation of irrigation schemes is of great importance. In Turkiye, irrigation schemes are managed and distributed by organizations such as water user associations, municipalities, and irrigation cooperatives. In Türkiye, irrigation schemes with an service area of 500 ha or more are managed by water user associations. In this study, Ahmetli, Salihli and Menemen water user associations’ irrigation schemes, where the Gediz River is used as a water source, were chosen as materials. The selected irrigation schemes service area constitutes 60% of the total service area in the region (DSI (General Directorate of State Hydraulic Works) 2nd Region(Aegean region)). The service area of Ahmetli irrigation scheme is 50,532 ha, 22,797 ha in Salihli and 22,865 ha in Menemen. The main crop pattern of the irrigation area is vineyards, corn and cotton. These irrigation schemes were evaluated using performance indicators such as water supply, irrigation rate, and amount of irrigation water used per unit area. The raw data sets obtained from DSI cover the years 2007 and 2021. As a result, when looking at the average performance, relative water supply, irrigation rate and amount of irrigation water used per unit area were found to be 0.70, 57.99 and 7682.45 m3 ha-1, respectively. Although 70% of the irrigation water need can be met with the water diversion to the system, the irrigation ratio was approximately 58% indicating the problems in transferring water to the system and the irrigation techniques used by farmers on the field are not modern. In addition, the main reasons for the unirrigated areas, are social and economic reasons (137 ha in the Menemen WUA) and the lack of water supply in the Salihli and Ahmetli WUAs, respectively, 2319 ha and 11320 ha cannot be irrigated, respectively. Modernization seems inevitable for more effective use of our water resources. The most effective techniques in this modernization are land consolidation, renewal of irrigation channels, extension and consultancy services to farmers, and making water fees according to volume can be counted.

Gothic Locks: Pioneering Drawings for Hydraulic Works in 16th-Century Holland

Just as Gothic cathedrals have long dominated the perception of medieval architecture, the spectacular drawings of the German lodges have shaped our view of the medieval design process. However, their towering importance has diverted scholarly attention from alternative drafting practices and reinforced the view of a homogeneous Gothic design practice based on quadrature. Historians generally accept that in the 16th century a new Renaissance graphic language challenged and ultimately replaced the Gothic tradition north of the Alps. However, this antagonistic narrative of one dominant practice superseding the other needs to be re-examined because hitherto neglected drawings for other types of buildings reveal that medieval drafting practice was more varied and open to new developments than is often believed. This paper will examine three rare sets of architectural drawings, together consisting of over thirty sheets, made for three stone sluices in the provinces of Utrecht and Holland between 1556 and 1563. They show that for technically demanding hydraulic works, drawings directed every step of the process, from enabling discussion of the most suitable design to guiding the stonemasons in the execution of the work. Moreover, they demonstrate that for such projects, Gothic masters did not adhere to tradition but engaged with new design methods, using scale, colour, and multiple views to convey all aspects of the project, thus indicating that changes in style and method were not always interrelated.

Climate-driven versus anthropogenic induced erosion of the last 3000 years from an ancient lake in the Southern Phokis Plain (Desfina), Greece

The timing and causes for erosional events at the Kastrouli (Greece) archeological site – a Late Myceneaen with reuse in later periods – are presented. Two borehole sediment cores (max 6 m depth), collected from the footsteps of the settlement hill plain, were studied. Sedimentary analysis and luminescence dating techniques investigate and identify periods of soil aggradation in this record. Moreover, optically stimulated luminescence (OSL) dating confirmed the concept of an ancient lake during Kastrouli settlement times. Macroscopic overview of the stratigraphic structure for each core, included lithological and textural evaluation of the core sediments, assessments of grain size, and determination of the geochemical and mineralogical composition of the sediments. X-ray powder diffraction (XRPD), X-ray fluorescence (XRF), and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) techniques were applied for the mineralogical and geochemical analysis. OSL ages from seven sediment horizons spanned from the Ottoman period to archaic times. All lithological findings correlate with the results of the electrical tomography survey conducted in same area. Extrapolation of the Logarithmic fitting of the data back in time of prehistoric Late Mycenaean era of Kastrouli verifies a lake deeper than 10 m, with a considerable enhancement in soil aggradation of 1.2 cm/year. Attempts to dry out the area are evidenced by the hydraulic works found in two engineering sinkholes. Sedimentation changes had occurred in the local environment over the last 2500 years, and soil aggradation underwent significant fluctuations in the two studied cores. The Roman period (a wet period) and the Byzantine period experienced high aggradation rates. By contrast, soil aggradation rates in southern Phokis (Kastrouli region) have remained exceedingly low from the Ottoman era (circa 13th century) to the present. In the context of the Phokis case study, it appears that the sedimentation rates, driven by climate, have strengthened anthropogenic activities.

Groundwater Level Estimation With Analytical Hierarchy Method

Groundwater is an important component of the hydrological cycle and a critical resource for ecosystems and human life on Earth. Estimation of groundwater levels is important for strategic planning and management in many areas such as agriculture, industry, engineering studies, and drinking water. In particular, it is necessary to determine the groundwater accurately and clearly in order to carry out both ground and hydraulic works. In this study, the estimation of the groundwater level of Diyarbakır province was made by analytical hierarchy method. Groundwater level estimation was made using slope, geology, geomorphology, land use, precipitation, fault density, drainage density classes. Especially in areas where data supply is short, positive and accurate results can be obtained with AHP, which is a fast and practical application. It is expected that the findings obtained will benefit public and private institutions and organizations for future studies.

Scan-to-HBIM-to-VR: An Integrated Approach for the Documentation of an Industrial Archaeology Building

In this paper, we propose a comprehensive and optimised workflow for the documentation and the future maintenance and management of a historical building, integrating the state of the art of different techniques, in the challenging context of industrial archaeology. This approach has been applied to the hydraulic work of the “Sostegno del Battiferro” in Bologna, Italy, an example of built industrial heritage whose construction began in 1439 and remains in active use nowadays to control the Navile canal water flow rate. The initial step was the definition of a 3D topographic frame, including geodetic measurements, which served as a reference for the complete 3D survey integrating Terrestrial Laser Scanning (TLS), Structured Light Projection scanning, and the photogrammetric processing of Unmanned Aircraft System (UAS) imagery through a Structure from Motion (SfM) approach. The resulting 3D point cloud has supported as-built parametric modelling (Scan-to-BIM) with the consequent extraction of plans and sections. Finally, the Heritage/Historic Building Information Modelling (HBIM) model generated was rendered and tested for a VR-based immersive experience. Building Information Modelling (BIM) and virtual reality (VR) applications were tested as a support for the management of the building, the maintenance of the hydraulic system, and the training of qualified technicians. In addition, considering the historical value of the surveyed building, the methodology was also applied for dissemination purposes.

Assessment of Environmental Risks of a Shallow Water Body during Dredging Works

Introduction. The increasing anthropogenic impact on water bodies necessitates integrated solutions to assess environmental risks. Literature describes the stages of risk assessment, the possibilities of environmental management, and expert analysis, while risk modeling in this field is being investigated. However, the potential for predicting risks to water quality and biodiversity during frequently performed hydraulic engineering works such as dredging has not been fully explored. The relevance and practical significance of such an approach are evident. This study aims to develop a mathematical model and software package that can assess risks to species diversity of the ecosystem of a shallow reservoir ecosystem during work in its water area.Materials and Methods. The starting point for the simulation was a description of the movement of water masses based on the Navier-Stokes equations and the continuity equation at variable density. We used the diffusion-convection equation to predict the transfer of suspended and dissolved particles, as well as to assess the impact of impurities during eutrophication. To create the algorithm, we utilized the terms and definitions defined by the state standard for risk management in emergency situations.Results. To test the solution, we took data on hydro-mechanical work in the port area of Arkhangelsk. We visualized the concentration fields of suspended particles 0, 15, 30 and 45 minutes after the soil was unloaded. It was found that during the settling of the suspension, the area of its distribution expanded significantly, and this was fully consistent with the data of field experiments during dredging. We calculated and tabulated the volumes of contaminated water at soil dumps in three sites (with a single discharge and in total). To assess the risks to the Sea of Azov, we used the maximum concentrations of pollutant (copper) obtained through measurements, modeling and remote sensing of the Earth. In tests to determine the potential danger of the substance, we assumed that its concentration caused a reaction in 50% of organisms. For fish, the potentially dangerous concentration was 4 mg/l with a duration of 96 hours of exposure. For zooplankton — 50 mg/l and 48 hours. For microalgae, 20 mg/l and 72 hours. The normalized risk value Rn ≈ 0.52 was obtained. The risk of copper concentration of 80 µg/l in the waters of the Azov Sea was recognized as significant. A tendency towards increasing salinity and stratification of water masses in terms of oxygen content has been identified, consistent with the findings of expeditionary research.Discussion and Conclusion. The developed approach has allowed us to assess the change in the quality of the waters of the Azov Sea and describe some transformations of the water area. Specifically, we are talking about the distribution of suspended particles and areas of their deposition. These processes can lead to changes in the bottom topography, which in turn can reduce the species diversity of the ecosystem.

On the Occurrence of Extreme Rainfall Events Across Italy: Should We Update the Probability of Failure of Existing Hydraulic Works?

Every year, extreme rainfall events cause human deaths and economic losses around the world. Risk reduction strategies may involve the implementation of structural measures that are widely extended and financial relevant. Despite the high reliance on these mitigation measures, there might occur instances of overload, i.e. events with intensities exceeding the design value of these structures, that may have catastrophic consequences. In this framework, it is crucial to improve hydraulic works management, thus, we introduce a procedure at rain gauge scale for revising design variables throughout their operational lifespan. This enables us to enhance the assessment of the probability of failure of these works. Finally, we investigate instances where design variables experience overload during the recording period, thus assessing the occurrence of rare yet possible events. To this aim we find the most-suitable probability distribution to describe daily rainfall maxima in Italy. Specifically, we test the performance of four widely used bi-parametrical distributions with different tail behaviour, by analysing an impressive dataset consisting of 2282 rain gauges observations from 1860 to 2022. Our results show that: (1) 78% of the empirical samples exhibits heavy-tail behaviour; (2) when the update procedure is applied, 64% of the samples shows a higher-than-expected probability of failure; (3) at least one case of overload associated to a 100-years return period is recorded in almost all regions. Based on our results, existing hydraulic works designed to safeguard populations and their activities from catastrophic events may face a higher risk of failure than initially expected.

Seasonal variation of the water quality in an intermittent river perennified by hydraulic work: a case study of the Terra Nova river basin, Northeast Brazil

The hydrographic basins inserted in the Brazilian semi-arid region tend to aridization and intermittency due to climatological and geological conditions, suffering great anthropic pressure and experiencing seasonal changes in water quality. The aim of this study was to analyze the seasonal variation of the water quality in an intermittent river perennified by hydraulic work: a case study of the Terra Nova river basin (TNRB), located in the state of Pernambuco, Brazil. Physical, chemical and biological parameters were analysed. Water samples were collected at eight sampling points in the TRNB, from 2009 to 2022, totaling 26 campaigns. The Water Quality Index (WQI) adapted by the Environmental Sanitation Technology Company of the State of São Paulo (CETESB) was applied. The results were evaluated spatially and temporally. It was observed that in most campaigns there was no water at the monitoring points, both in the rainy season (77.8%) and in the dry season (73.5%). During the sampling period the WQI ranged from Excellent (81) to Bad (24) in the TNRB. Point Q06 stood out from the others, presenting the only WQI classified as Excellent. With regard to seasonality, the dry season ranged from Excellent (81) to Bad (24), while in the rainy season it ranged from Good (78) to Bad (22). To improve water quality it is necessary to invest in basic sanitation in the TNRB municipalities, environmental recovery, environmental education and monitoring with the aim of mitigating conflicts and impacts.

Characteristics of packing gland seals in hydraulic systems of quarry excavators and results of comparative analysis of experimental tests

The efficiency of quarry hydraulic excavators will depend on several factors, namely the climatic conditions of the area where hydraulic excavators are used, the degree of air pollution (pollination), the performance of the structural parts of the excavator, the reliability of the hydraulic system, the performance and cleanliness of the hydraulic working fluid. In this area, research was carried out on the performance of seals used in the hydraulic system of quarry excavators. The article presents the results of experimental tests of the existing type of oil seal a and b, as well as the proposed oil seal type c, shown in Fig. 1.

From Cut-in to Qanats - Ancient Groundwater Extraction Techniques

Where a hillside stratified aquifer intersects the earth surface, springs and outseeping are observed. Cutting into this zone, thus opening it by digging, allows to increase and capture water outflow. As a matter of principle this classical method for water extraction without pumping, which is still found in hilly rural regions today, was already used 3600 years ago by the Hittites to fill the ponds of their capital Hattuşa in Central Anatolia. The today sedimented reservoirs were dug downhill of groundwater bearing zones. Rising in winter, groundwater discharged into the ponds through alongside cuts. The Hittites avoided the risks of strongly varying surface flows by opening near-surface groundwater and stratum aquifers. Although hydraulic investigation based on in-situ measurement of groundwater level supports the short-term efficiency of the ponds in supplying water to the ancient city, at the long-term, the decline of the Empire was probably triggered by severe droughts expanded over years. This seems plausible as severe droughts are still being experienced. For a higher and more reliable water yield, the further development went from ’cutting’ in to ’penetrating’ into the aquifer with tunnel-like drain conduits which collected the water and conveyed it to settlements and irrigation schemes. The improved water extraction system, named qanats, appeared in Eastern Anatolia and Persia about 500 years after the abandon of Hattuşa. An example of a qanat system in western Iran is presented in this study with less emphasis compared to the cut-in yet representative enough to demonstrate its role in supplying water sustainably. We conclude that the ancient time thinking is the same as that of modern engineering, and the ancient time hydraulic works are fundamental for today's civil structures.

Propuesta de estrategias estructurales para mitigar inundaciones en la microcuenca Santa Rosa Jáuregui, Querétaro

In the metropolitan area of Queretaro (ZMQ) recurrent and dangerous floods are formed, to mitigate them, focused hydraulic infrastructure works have been built that do not always take into account the water dynamics of the territory. Therefore, in the present work, structural strategies were designed in the Santa Rosa Jauregui micro-watershed to contribute to flood mitigation in the urban periphery of the ZMQ. The methods include a multi-criteria analysis with geographic information systems to determine priority sites and then structural strategies were designed with the water dynamics of the micro-watershed. The results present four priority sites distributed between the middle functional zone and the low functional zone of the micro-watershed, and four structural strategies were designed to mitigate floods. This concludes with a work that will allow the population and authorities to have information and options for decision making in flood mitigation.

A press tool is a tool to help shape, bend, cut products from sheet metal (plate) base material which is operated using a press tool. To increase effectiveness and productivity, currently many hydraulic systems are combined with other systems such as electrical/electronic, pneumatic and mechanical systems so that more optimal hydraulic system work can be obtained. This press applies pressing or loading movements using hydraulic power. In order for the pressing process to be even or precise, one cylinder is needed which moves the top plate (Punch). The working load on the single acting cylinder has a maximum capacity of 20 tons. The design of this press tool is designed by following the type and shape of the selected material sample. The design of this press tool aims to make the user's work easier to get more precise press results. The material used is profile steel. Simulation results on the press frame: frame length 400 mm, frame width 600 mm, frame height 850 mm, frame strength 16407 N/m2

Myths, Falsehoods, Paradoxes, Errors and Virtual Water in Mediterranean Europe: The Case of the Iberian Peninsula

The statement that everything remains the same in Mediterranean Europe in matters of continental waters following the course of the last three decades is untrue. In effect, following the drought of 1995 or perhaps coinciding with it, social movements and a high proportion of scientists and even numerous members of the administrations have dealt extensively with the issue. As a result of the many books, articles in scientific journals and conferences, etc., expression New Water Culture, demand management, water quality etc. are today highly promoted amongst academics and managers to such an extent that they considered themselves as fellow believers of these new tendencies in water policy or, at least, few dare to publically state their opposition to them. But, in reality, have the aforementioned changes and other developments substantially affected the principles that inspire current hydropolitics in Mediterranean Europe? Or, on the contrary, do “old ghosts” reappear whenever there are periods of less rainfall? This article discusses and differentiates some aspects of the water situation in Mediterranean Europe and, above all, the correlative management models that have been developed in recent decades with a particular analysis of the cases of Spain and Andalusia. It asks whether the previous diagnosis is still correct today or, on the contrary, the cultural and institutional changes that have already taken place have been appropriate and sufficient for the establishment of a New Water Culture in Southern Europe. Frequently used terms, expressions and concepts such as throwing water into the sea, hydraulic works are in the general interest, wet Europe and dry Europe, the water transfer will definitively solve the problem, water deficit, water must be distributed fairly, everyone has a right to water, water is a public asset etc. shall be reviewed from a scientific approach. The concept of water scarcity is normally unquestioningly assumed by people and the administrations that irrationally integrate it into public policy. This article discusses and differentiates the concepts of physical and economic scarcity, of the prices and effects these have on the efficiency and equity of water management and usage. As well as an analysis of the problem of the pollution of continental waters, there is also a brief examination of the pollution caused by their discharges into the Mediterranean Sea. There is a discussion of a number of general comments in regards to water transfers and provide a short overview of three of the most controversial of these works in Spain: The Ebro-Almería, Tajo-Segura and the Castril River Water Transfer. A new line of research is presented for the management of water, the virtual water approach that produces and confirms the results I already previously obtained through conventional procedures. The last section describes the economic effects on agriculture and tourism that climate change is causing in a number of Mediterranean regions. It is to be stated in advance that the conclusion is: The New Water Culture (NWC), from the South, demands the prior recognition that the biggest statements on the scarcity of water are not the result of climatic conditions, rather, they are due to the economic development and social model followed, misgovernment by competent institutions and, definitively, because the conflicts made evident between different users have solely been resolved with arguments of political and, ultimately, economic power.

Resistance and durability of high strength geotextile bags for hydraulic works

There is a need to build hydraulic works for riverside protection in case of flood as well as a mitigation project for high scour in places where rock material is very expensive or does not exist, therefore hard armour rock, rip rap or even concrete are unattractive alternatives. In several countries of the world, geotextile bags of high resistance have been used to achieve a valid and economical alternative. Themes related to stability of structures with bags that are very important have been dimensioned by some researchers, but there is still no information on how to relate the mechanical characteristics of the components of the bags with their manufacturing and also its service behaviour. This research offers details to be able to know the mechanical characteristics of thread types, geotextile and seaming according to the infill material type to be used to have an equivalent of a rock with the use of high resistance geotextile bags. This is also oriented to know its durability before abrasion, impact and UV radiation. Tests carried out in our laboratories are included as well as those carried out by other researchers both oriented to a methodology that provides an appropriate dimensioning of this type of structures. Some experiences where this methodology was used will be also included as well as the appropriate references.

Experimental evaluation of water infiltration through concrete-geocell liners

In this article we study the infiltration rate and flow characteristics of water through concrete-geocell liners by experimental and analytical means. Geocells filled with concrete have been used in the construction of many hydraulic works, such as shore protections (both marine and riverine), spillways, and canal liners; these liners have been reported to offer high performance, as they are able to withstand large flow velocities, hydrodynamic effects, and environmental stresses, while still being more cost-effective than other hard-armor systems such as reinforced concrete and articulating concrete blocks (ACBs). Despite their increasing use there is no report of their hydraulic conductivity in the literature, which this paper aims to fulfil. First, an analytical solution to the problem is achieved by parting from the incompressible Navier-Stokes equations and applying reasonable assumptions to arrive at a formula that relates flow rate to pressure gradient, fluid properties, and importantly, the hydraulic aperture (the idealized gap at the concrete-geocell interface); this gap is then estimated using the ACI-209 method for the prediction of concrete shrinkage, resulting in the proposed semi-analytical method. The formulation was then evaluated experimentally by conducting hydraulic tests on full scale geocell specimens filled with concrete under conditions that are deemed representative of real case applications. The results indicate that the proposed methodology has satisfactory predictive capabilities and provides flow rate estimates in accordance with measured data.

Investigation of chemical change in water quality and spatial modeling with GIS mapping: A case study from Beşgöz Lake in Konya Province of Türkiye

In this study, Beşgöz lake in Sarayönü district of Konya province, located in the Central Anatolia Region of Türkiye, was chosen as the study area. Rehabilitation work was carried out in 2020 with the resources of the State Hydraulic Works. The average depth of Beşgöz Lake was increased from 4 m to 8.5 m, and its surface area was increased from 86.000 m2 to 230.000 m2. Beşgöz Lake, located in Sarayönü district, provides water from underground sources at the bottom of the lake. These underground sources come from the gaps in the limestone in the lower parts of the lake. When looking at the geological map, it is thought that there is a connection between Beyşehir Lake and Beşgöz Lake because the land has a calcareous structure. The changes in the water quality parameters of Beşgöz Lake in different periods were examined and spatially modeled using spline interpolation techniques with Arc GIS 10.3.1 program, one of the Geography Information Systems (GIS) software. In order to determine some water quality parameters of Beşgöz Lake, water samples were taken from eight different points representing the lake in 4 different periods (Spring, Summer, Autumn, Winter). Seasonally in the water of Beşgöz Lake, water quality parameters such as pH, Electrical Conductivity (EC), Temperature, Chloride (Cl), Nitrite (NO2), Nitrate (NO3), Sulphate (SO4) Chemical Oxygen Demand (COD), Suspended Solids (TSS), Boron (B) were investigated. As a result of the research, it was found that pH values varied between 7.77–8.42, EC: 268–470 µS/cm, water temperature varied between 6.8–20 °C, Cl varied between 0.139 - 3.9 mg/L, NO2 varied between < 0 00–0.33 mg/L, NO3 varied between < 0.00 - 4.13 mg/L, SO4 varied between 0.057 − 18.4 mg/L, COD varied between 5–32, TSS: 0.60 - 31.8 and B varied between 0.05–0.093 mg/L. As a result of the study, it was seen that the water quality of Beşgöz Lake, which is the subject of the research, is class I and potable water quality.
