Comparative Analysis of Sponge City Drainage System Schemes Based on SWMM

In this paper, the drainage system schemes of sponge city are compared and analyzed based on Storm Water Management Model (SWMM). First, this paper builds a model in SWMM to explore the effect of green roof, rain garden and reservoir on solving the excessive pressure of urban drainage system during rainstorm, and analyzes the results of the model. Through comparative analysis, the best scheme is obtained. The results show that the green roof has the best effect among the three schemes, which can reduce the flow of the pipeline, increase the drainage cycle and thus reduce the pressure of the drainage system. Second, limited by the size of the area, it can only reduce the flow of the drainage system. The reservoir has the worst effect, mainly because the intensity is not large enough, and if it encounters greater rainfall, the reservoir can play a key role in regulating and storing. Through the analysis of the model results, an effective scheme can be obtained to relieve the pressure of urban drainage system in rainstorm, so as to reduce the drainage pipe flow and reduce the risk of urban waterlogging. The purpose of this paper is to provide effective reference for the construction of sponge city, relieve the pressure of drainage system and reduce the hidden danger of urban waterlogging.

Effects of Aquatic Physicochemical Parameters Variation on the Phytoplankton Abundance and Diversity in the Babon River, (Semarang, Central Java, Indonesia)

The Babon River is an integral component of Semarang City's drainage system, which is heavily impacted by the influx of waste, leading to elevated water temperatures caused by global warming and decreased pH levels due to acid rain. The two main environmental factors that affect phytoplankton growth and productivity are temperature and nutrient availability. Nutrients can change the balance of the natural food webs of aquatic ecosystems. Meanwhile, metals are toxic and can accumulate in biota tissues. This study examined how nutrients, pH, temperature, and heavy metals in water affected the diversity and abundance of phytoplankton. Water samples and phytoplankton were collected from 7 observation stations representing the upstream, middle, and downstream rivers. Observations at each station were made 3 times in the months of April-May, June-July, and August-September. Temperature and pH were measured in situ with the HORIBA Water Checker. Analysis of nitrate, phosphate, and heavy metals was carried out with an AAS. The results showed that the dominant phytoplankton in the Babon Rivers consisted of Bacillariophyceae, Chlorophyceae, and Cyanophyceae. There is no diversity against all independent variables (temperature, pH, nitrate, phosphate, Cd, Total Cr, Pb concentrations) and dependent variables (number of genera, abundance, and diversity index of phytoplankton) due to the sampling station's location. However, sampling time caused diversity in nitrate, phosphate, Cd, Total Cr, and Pb concentrations, the sampling location effect was more dominant than sampling time, so the results showed that all independent variables did not contribute significantly to the dependent variables.

Sponge City Drainage System Prediction Based on Artificial Neural Networks: Taking SCRC System as Example

The concept of sponge cities is widely recognized, but there is still no research on what a new drainage system for sponge cities should look like. This study proposes a new drainage system for sponge cities, a sponge-type comprehensive pipe corridor rainwater chamber (SCRC) system, which combines a comprehensive pipe corridor with low-impact development measures (LIDs) into one system. The SCRC system is predicted by using a long- and short-term neural network to verify whether the neural network can be applied to the prediction of flooding in sponge cities. The results show that the SCRC system can effectively control sponge city flooding, where the surface runoff coefficient under different rainfall intensities (P = 1–10 yr) is between 0.273 and 0.44, the pipe overload time is between 0.11 and 3.929 h, and the node overflow volume is between 0 and 23.89 Mltr. The neural network has a high reliability in sponge city flood prediction, and the coefficients of determination R2 of the test set of PSO–LSTM prediction models are all above 0.95. This study may provide an idea for predicting flooding in sponge cities.

ROAD DRAINAGE SYSTEM DESIGN EVALUATION (CASE STUDY OF PRAMUKA ROAD, BANJARBARU CITY)

The drainage canal development project discussed is one of the projects undertaken by the Public Works and Spatial Planning Office of the City of Banjabaru. This drainage is located along Jalan Pramuka, North Loktabat. As a result of changes to the urban planning system in the city of Banjabaru, the work on improving the city's drainage system on the surrounding roads began. Many things cause an increase in the flow coefficient, which can trigger sedimentation in drainage channels and even runoff in the following years. The causes include the development and increasing density of the urban area of Banjarbaru and the bad habits of the people, such as throwing garbage in the canal.This research aims to redesign the drainage system in order to obtain a drainage network system that is more optimal in terms of environment, materials, and costs. This research was conducted by analyzing the design flood discharge at the location of the Banjarbaru City Urban Drainage System Development Project, calculating the existing drainage system calculation analysis, and evaluating a more optimal and economical drainage system design that could be suggested.Data analysis was carried out by hydrological analysis and hydraulic analysis. Furthermore, to process the data obtained, several calculation steps are carried out, such as processing daily rainfall data, frequency analysis, and discharge calculations. Through these calculations, the design discharge Qr 2 years is 0.0733 m3/second, Qr 5 years is 0.1075 m3/second, Qr 10 years is 0.3280 m3/second, Qr 15 years is 0.3599 m3 /second, Qr 20 Years of 0.3827 m3/second. The cross-sectional size of the box culvert used was 50 x 40 x 100 x 15 cm with a discharge capacity of 0.4148 m3/second, while the size of the masonry used was 30 x 40 x 40 with a discharge capacity of 0.4367 m3/second. Keywords: discharge plan, highway drainage, discharge capacity, runoff, channels

The multidimensional nature of the Environmental Contribution for environmental qualification in São Paulo

This paper describes the conception of the Environmental Contribution instrument in the municipality of São Paulo, with the aim of exploring the multidimensional nature of this instrument, namely: its potential to promote improvements in the city's drainage system, microclimate conditions and biodiversity, as well as encouraging the development of sustainable buildings through certification and promoting environmental quality in the densification process. It also takes stock of the implementation of the instrument in the city of São Paulo between 2016 and 2023, through the project approval reports from the Municipal Urban Planning and Licensing Department (UPLD). In this context, the multidimensional nature of the instrument and its high potential to promote improvements in the city's environmental quality and to contribute to São Paulo's adaptation to the impact of climate change are proven. At the same time, the instrument's scope is limited, and it urgently needs to be improved so that the Environmental Contribution has a wider reach in the territory and is consequently more effective in improving the city's environmental quality.

Occupational skin cancer screening: Results of a cross‐sectional study at the city drainage company Munich

AbstractBackgroundSince skin cancer incidence and prevalence are rising steadily, the prevention of skin cancer has gained importance. People with high sun exposure at work are at special risk, and prevention measures by the employer may lower the risk, especially for keratinocyte carcinoma.ObjectivesThe aim of the study was to evaluate the results of a large‐scale skin cancer screening campaign at the city drainage company Munich where the cohort consisted mainly of outdoor workers.MethodsIn 2023, a skin cancer screening campaign was conducted at the city drainage company Munich. Sun exposure and protection measures of each participant were assessed using a questionnaire. Dermatologists identified clinical signs for sun damage and skin cancer by whole‐body skin examination.ResultsA total of 290 participants (72.8% male; mean age 43.7 ± 11.5 years) were enroled. 36.6% showed clinical signs of sun damage correlating with male gender, higher age, and more hours spent outdoors per day. Clinical examination revealed a suspect finding of skin cancer, a preliminary stage, or a lesion requiring clinical control to avoid skin cancer development in 19.3% of participants. Participants with atypical melanocytic lesions were mostly female and showed a high skin cancer awareness. This was concluded from the fewer signs of sun damage, a higher percentage of previous screening participation, and more regular self‐examination.ConclusionsWhole‐body examination for skin cancer screening at work is a valuable tool to encourage participation in this preventive measure. It may help identify people at risk either by clinical signs for sun damage or risk exposure which can be assessed with a simple questionnaire. Based on this result, the screening interval may be adopted individually.

Assessment of Municipal and Industrial Wastewater Impact on Yamuna River Water Quality in Delhi

Delhi's Yamuna River serves as a notable illustration of an ecologically compromised system that has undergone a transition into a conduit for sewage due to pervasive pollution and escalating anthropogenic influences. Delhi, being the primary contributor to pollution, is responsible for over 70% of the total pollutant load in the Yamuna. The city's drainage systems discharge a substantial Biological Oxygen Demand load into the river daily, resulting in severe pollution. This research utilizes pre-existing data to examine diverse factors, evaluating the quality of water at distinct observation locations along the Yamuna. The utilization of correlation analysis aids in recognizing connections among elements influencing the pollution of river water. The outcomes of the correlation analysis disclose a notable link between COD-BOD factors, whereas the connections among alternative factors like BOD-DO, BOD-pH, COD-DO, COD-pH, and DOpH range from moderate to negligible. The majority of observed parameters exceed hazardous levels deemed acceptable for river water utilization. The evaluation of Sewage Treatment Plants highlights the imperative to augment capacity in terms of treatment, storage, reactivation of closed plants, and efficient operation to meet the growing demand for fresh water. Additionally, there is a pressing need to generate demand for wastewater in diverse urban sectors.

Development and implementation of industrial wastewater treatment technologies

The results of the Igor Sikorsky Kyiv Polytechnic Institute the Department of Bioenergetics, Bioinformatics and Ecobiotechnology researches in two directions: 1 - research into the processes of physical and chemical purification of industrial wastewater of a number of industrial enterprises from antibiotics, heavy metal ions, synthetic surfactants, etc. pollutants, and the development of local cleaning technologies before discharging pre-treated wastewater into the city's drainage network; 2 – study of processes of biological wastewater treatment of industrial enterprises with deep removal of nitrogen and phosphorus compounds using immobilized microorganisms. The greatest decrease in the COD index was observed in the processes of coagulation and settling of wastewater of a pharmaceutical enterprise. The effects of purification according to the COD indicator in the case of using ferrous sulfate III were 76.0% and 72.2% for the initial values of COD of untreated wastewater, respectively, 90 and 120 mg/dm3. For biological purification, microorganisms immobilized on VIA carriers were used in oxygen conditions created in model bioreactors - anaerobic, anoxic, aerobic. To increase the biomass, we used nylon textured thread according to TU 6-06-S116-87 with a fiber diameter of 1.5-2.5 mm and a microfiber diameter of 100 μm. The specific surface area was 4000-5000 m2/m3. The average concentration of biomass in bioreactors by dry matter, g/dm3, was: in anaerobic I – 30; in anaerobic II – 24; in anoxic I - 16.8; in anoxic II - 5.4; in aerobic - 3.2. Biological treatment of industrial wastewater using immobilized microorganisms made it possible to obtain high pollutant removal effects. The indicators of purified wastewater were: COD - 50-80 mg/dm3; BODfull - 15-20 mg/dm3; suspended substances - up to 15 mg/dm3; compounds of nitrogen and phosphorus - within the norm for discharge into natural water bodies. The developed technologies were implemented at industrial enterprises, the savings in energy costs amounted to 40-45%, the high quality of purified water was ensured in accordance with the current standards for discharge into the city drainage system and into natural reservoirs.

Assessment of the Seasonal Variations of Lakes Water Quality in Bangladesh

The study was conducted to assess the seasonal variations of water quality in Hatirjheel Lake and Dhanmondi Lake during the period from August, 2019 to January, 2020. The water samples were collected monthly during the monsoon and postmonsoon seasons from five sampling stations of both lakes. Comparative analysis revealed that mean pH was near the standard level in both lakes where DO concentration was much lower in Hatirjheel Lake than Dhanmondi Lake which could be due to the direct dumping of nearby residential and commercial waste, and domestic sewages from the city drainage system as well. The BOD concentration in Hairjheel Lake water exceeded the standard in both seasons and there was no significant change over seasons. In contrast, the Dhanmondi Lake water showed relatively lower BOD concentrations in both seasons where mean concentration slightly exceeded the standard in some stations. The EC and TDS contents showed positive relations but exceeded the standard limit throughout seasons in both lakes. The nutrient contents (NO3 -, NO2 - and NH4 +) of Hatirjheel Lake water highly exceeded the standard during the study that tends the lake water prone to eutrophication. The study revealed that the physicochemical parameters and nutrient status of Dhanmondi Lake water were within the standard limit except EC indicating a rich habitat for aquatic organisms and sounds for recreational activities than Hatirjheel Lake which should be monitored throughout the year to maintain the productivity of lake water systems.

Kajian Upaya Mitigasi Struktural dan Nonstruktural Bencana Banjir di Kota Kendari

The government and the community need to take various mitigation measures to reduce the impact and losses caused by flooding in Kendari City. This study aims to examine flood disaster mitigation efforts implemented in Kendari City. Qualitative descriptive research was applied and analyzed using the Miles and Hubermann analysis method. The structural mitigation efforts carried out between the Kendari City Government, stakeholders, and the community include the construction of river embankments, flood retention ponds, repair of the city's drainage system, installation of river water level monitoring devices, installation of flood-prone signs, and disaster evacuation routes, as well as the construction of embankments and modifications to the house building.

Investigating the Impact of Flood on Low Lying Settlements of Delhi, India: A Planning Perspective

In the past, the Yamuna River and the Najafgarh Drainage System have flooded the city of Delhi severely. In the past 33 years, Yamuna has 25 times exceeded its risk threshold, which is set at 204.83m. Since 1900, Delhi has suffered six significant floods when the Yamuna River has reached a height of one metre or more above the accidental 204.49m on the old railway bridge (2.66m above the accident level). These floods happened in 1924, 1947, 1976, 1978, 1988, and 1995. The Yamuna recently climbed more than two metres beyond the danger threshold in Delhi, breaking the milestone 207 metres for the first time in 32 years. The second highest point, at 206.92 metres, was on September 27, 1988. There is a direct impact of floods on the Yamuna River and the city drainage network. People who live along the Yamuna River Belt, on the river's banks, and in the drain are impacted by this. The amount of the solid regions causing local floods has increased landslides as a result of deforestation and local floods. Low-lying communities, particularly haphazard colonies that fall into the water, will be most impacted by this. Hathinikund erupts high in Haryana because of the persistent, intense rainfall on the high cliffs, draining water upstream, continuing to flood Delhi and harming the lives of those who live in low-lying areas. Therefore, torrential rains caused severe damage to the city, and even more so to those families built on the wrong side, which were the first and most frequent sightings of their homes and property being flooded. Families had already begun to lose livestock and livestock during this time, before being evacuated and their situation remains so dire that one has to leave the rest of the house to relocate and relocate when the water level drops. The purpose of the study was to explore about the kind of impacts generally inhabitants face during and post flooding and to find out the implementation of strategies. The following methods were used: Site survey of the case study area in which structured questionnaire and observations were conducted through primary survey, analysis and assessment, study of issues and concerns. As a result, flood prevention, preparedness and mitigation strategies with reference to low lying area have been analyzed and planning recommendations have been proposed.

Evaluating the Capacity of Existing Stormwater Drainage System in Kapan, Kathmandu via SWMM Mode

Overflowing drainage systems in the Nepalese cities are the most significant issue due to unplanned urban expansion and inadequate drainage networks. As the city's drainage networks are not designed to handle the extra runoff from catastrophic flooding incidents, flash floods typically occur during short-duration, and high-intensity rainstorm storms frequently. In the vicinity of Kapan, Kathmandu, and many other Nepalese cities, particularly during the rainy season, roads are seen changing into the streams. This study employs a hydrological analysis model to examine the storm water drainage system existing currently in the Kapan area. Being the EPA Storm Water Management Model (SWMM) physically based, deterministic type that simulates the inflows, outflows, and storages of water within a sub-catchment efficiently, it is chosen here mainly to model the catchments specifically. Though it has not been employed frequently in the context of Nepal, despite its popularity in the industrialized countries such as United States of America for the proper management of the storm water, the SWMM is particularly employed here to model the catchments due to its publicly available, easy to obtain, simple data input parameters, and simple processing steps in compared to other relatively more expensive yet sophisticated models. The catchment's overall area of 360.57 hectares was at first separated into the 86 sub catchments using the SWMM based on its surface elevation and existing drainage network, and the attributes of each sub-catchment were then assigned accordingly. After the proper identification of the sub-catchments, the runoff from the relevant sub-catchments was routed to the respective nodes, and finally to the outlet via conduits. In the current study, the drain system (Combined Sewer line) is given along the center of the road network. The storm network are represented by junctions, conduits, and outfalls. The longitudinal and velocity profiles of the drain were obtained. The critical runoff and capacity of existing drains were determined, as well as their validation with discharge derived using the rational technique. With the runoff generated during peak rainfall 45.08 mm/hr., the Kapan area's existing drainage system was found to be insufficient. This study suggests that the SWMM would be the most effective model to be employed for predicting the sudden surface runoff and for prior managing of the storm water, particularly in Kathmandu and other vulnerable parts of main cities in Nepal, where overflow has caused serious problems during rainfall.

Study on the Division of the Affected Zone under Construction Unloading and Its Construction Sequence of the Multiline Parallel River-Crossing Pipe Jacking

There are many advantages of reasonably determining the affected zone and its construction sequence for the multiline parallel pipe-jacking construction, such as convenient to reasonably arrange the pipeline section distribution mode, reducing the construction safety risk, and construction difficulty. Combined with the engineering construction practice of the multiline parallel pipe-jacking project for the north city drainage and flood control project through Chu River in Hefei, the strength reduction method has been utilized to study the surrounding stratum FOS for the pipe-jacking construction unloading under different overburden thickness Hs, different clear distance D, and different river water depth H w in this paper. The formula of the minimum critical overburden thickness Hsmin and the minimum critical clear distance Dmin of the surrounding stratum self-stability during pipe-jacking construction unloading have been derived. The division method of the affected zone for the multiline parallel river-crossing pipe-jacking construction which behaves as the mutual influence nonself-stability zone, the mutual influence self-stability zone, and the no mutual influence self-stability zone has been proposed. For further discussion, the construction sequence of the multiline parallel river-crossing pipe jacking has been studied.

Urban Rainfall-Runoff Modeling Using HEC-HMS and Artificial Neural Networks: A Case Study

Urban flooding nowadays becomes common throughout the world. The main reason for these floods is rapid urban development and climate change. During the monsoon, the flows in the urban drains will be high and the main reason for these high flows is the existence of a combined network system (i.e. drainage and stormwater). Further, the flow in the city (under study) drainage network was very high and some areas of the network exceeds more than discharge carrying capacity. Hence, this may result in overflow from the manholes and create an overland flood problem. Rainfall-Runoff modeling in these situations in the urban catchment will be essential and required to understand the flow pattern that helps in flood management. Therefore, the current study chose Hydrologic Modeling System (HEC-HMS) and Artificial Neural Network (ANN) for rainfall-runoff modeling at an hourly period for the Kukataplly (zone-12) watershed of Hyderabad city, Telangana State in India. This zone-12 watershed was one of the most affected hydraulic zones of Greater Hyderabad Municipal Corporation (GHMC) during the monsoon period in the past 21 years. The present study focuses on a comparative study between HEC-HMS and ANN has been carried out to comprehend the flood scenario in the study area. Finally, the performance of the model is checked with statistical indices such as Nash-Sutcliff Efficiency (NSE), and Coefficient of Determination (R2). HEC-HMS yielded good results (NSE = 0.74 and R2 = 0.76) when it has taken care of the maximum possible nonlinear complex data to be analysed.

Analyzing Community Needs in the City of Urdaneta Using Text Analytics

Community needs assessments are one of the functions of city managers/administrators to find ways to collect accurate data/information that represent the most important needs of a community. In such assessments, a commitment to community participation is very important to determine current situations and identify issues for action, establishing the essential foundation for vital planning. That’s where a community needs assessment comes in; it can be used to inform and improve any community development initiative. The main objective of this study is to conduct a needs assessment focusing primarily on identifying community needs in the City of Urdaneta. This study utilized a mixed method whereby data were collected and analyzed quantitatively and qualitatively to analyze the community needs of the City of Urdaneta. The quantitative data were used to describe the population that resides in the city, and they were the respondents to the study. This method was utilized to obtain a direct picture of the services that the City of Urdaneta is providing to its stakeholders and provide a better understanding and explanation of their needs. The result reveals that respondents were not satisfied/dissatisfied with the drainage management provided by the city, especially when the rainy season comes, which resulted in flooded streets around the city. Based on the flood-prone map, some barangays were situated in flood-prone areas, worsening the flooding problem. The result also shows that the city should manage people with mental health and animals roaming around the city as they may pose a danger to the public. However, the respondent is satisfied with the services provided by the city based on the comments/opinions based on the word/ word patterns such as “improve services”, “good services” and “excellence services”. It is suggested that the city government should improve the city drainage system to eradicate or minimize flooding during rainy seasons, provide better mental services to stakeholders, and provide services that will control stray animals that roam around the city since they could endanger the public.

Urban drainage of the large cities in the Hydrographic Basins of the Piracicaba, Capivari and Jundiaí Rivers

The intense transformation of the landscape has been occurring dynamically in the Hydrographic Basins of the Capivari, Piracicaba and Jundiaí Rivers. This work aims to perform a survey of indicators related to the drainage of some municipalities inserted in these watersheds in order to point out the relationship of these indicators among the selected municipalities. The methodology used was a descriptive approach and case study. The indicators were selected and collected in the Stormwater section of the Historical Series of the National Sanitation Information System for the municipalities of Campinas, Indaiatuba, Jundiaí, Limeira, Piracicaba and Sumaré, years 2017 to 2020. The results suggest that the municipality of Campinas slightly outperforms the others. Moreover, the analysis of the indicators referring to urban drainage in the analyzed period revealed the need for reliable data to be later used in appropriate decision-making.

THE FREQUENCY AND IMPACT OF FLOODING IN THE SYLHET DIVISION OF BANGLADESH: AN INVESTIGATION

The recent flash floods in Sylhet and Haor areas this year were particularly devastating. In June 2022, the flash floods in Sylhet broke all the previous records in the country. In this terrible flood, about 90 percent of the area of the Sylhet division went underwater. This study investigated the impact of the recent flash flood of 2022, in the Haor areas of the Sylhet division. The impact of these disasters on human livelihoods and agriculture was identified using a mixed method (qualitative and quantitative analysis) approach from the field survey. Historical rainfall data (1970-2022) of Srimangal and Sylhet rain-gauge stations were collected from Bangladesh Meteorological Department (BMD). Field data were collected through four FGDs involving people of various sectors in the concerned areas. The study found one of the causes of the flash flood is the fact that 2017 and 2022 saw the biggest amounts of rainfall ever recorded, as well as abrupt, relatively significant rainfall over the summer. These flash floods happen because of heavy rainfall and hill slopes coming down from upstream, the sedimentation of canals and rivers, improper canal and river digging, and poor management of Sylhet city's drainage system. The research findings go into great detail regarding the local perspectives of the underlying problem, such as how crop damage results in increasing food shortages, rising poverty rates, debt, inequality, and uncertain livelihoods. Finally, a few potential solutions have been suggested in the study for minimizing the loss following such kinds of natural calamities.

And based on the problem of existing infrastructure, the Merdeka Square revitalization plan is very feasible to do.
 

Refleksi Tata Kelola Perairan Tradisional Handil dan Saka dalam Drainase Perumahan Kota di Banjarmasin

The tradition of Banjar farmers in making artificial rivers for water management in rice fields can be adopted as city drainage, especially in housing complexes. For the adoption to be successful, it is necessary to pay attention to how the water flow works to ensure its implementation, as well as development. The method used in this paper is qualitative. Data were collected based on direct observation activities, and supplemented with secondary data in the form of written sources, documents, pictures, and maps. The analysis was carried out by descriptive, comparison, and interpretation. The result obtained is the natural flow of water in artificial rivers applying a gravity system which is realized by placing attention to heights, in order from highest to lowest, rice fields, saka, handil, and natural rivers. The adoption of this pattern for drainage in housing complexes needs to take into account of the basic concept, and be developed according to current conditions. Therefore, it can be concluded that the way of regulation works with artificial river facilities is feasible to be adopted and applied to drainage in the current housing complexes.
