Assessing the effectiveness of adaptation against sea level rise in Japanese coastal areas: protection or relocation?

Sea level rise (SLR) due to climate change poses a serious threat to human populations in coastal areas. As a result, assessing the impacts of SLR and evaluating potential adaptations is essential. This study assesses the impacts of SLR and ocean tides on coastal Japanese prefectures by estimating the extent of potentially inundated areas, affected populations, and economic damages. The latest climate scenarios, tidal data, and shared socioeconomic pathways (SSPs) are used to estimate the SLR and its inundation effects at a resolution of 1 km. Economic damages are estimated following the methods outlined in the “Manual for economic evaluation of flood control investment (draft).” It was found that all impacts (inundated areas, affected populations, and economic damages) under RCP2.6-SSP1 are significantly smaller than those under RCP8.5-SSP5, suggesting the importance of mitigation efforts. In addition, the study evaluates the cost and effectiveness of protection and relocation adaptations using data on the cost of constructing dikes and the cost of relocating houses and infrastructure. While relocations due to SLR have not yet been undertaken in Japan, the relocation costs could be estimated based on the conventional scheme of community relocation for natural disasters such as life-threatening floods and tsunamis caused by major earthquakes. It was found that the costs of relocation can exceed those of protection under the current framework of Japanese relocation policies.

Accuracy Evaluation of Regional and Global Tidal Models (TPXO9 and Goddard Ocean Tide) at Kabil Tidal Station

Indonesia is an archipelagic country with a total marine area of 5.9 million km², consisting of 3.2 million km² of territorial waters and 2.7 km² of Exclusive Economic Zone waters, not including the continental shelf. With the vast waters in Indonesia, sufficient information about the tides is needed. Limitations of terrestrial tide data amidst the increasing need for marine information can be overcome by using global and regional tide models. This study uses the regional tidal data model released by BIG (Geospatial Information Agency) and the global tide model TPXO9 and GOT (Goddard Ocean Tides). From the two global tidal models, the tidal harmonic constant values are extracted at the tidal observation point in Kabil. Evaluation of global and regional tide models is carried out by comparing the amplitude values of the main harmonic constants of the tide models of global and regional tides with the amplitude values of the harmonic constants of terrestrial tidal measurement data to obtain a comparison of accuracy. The results of this research show the value of main tidal harmonic.

Identification of Sea Level Rise and Land Subsidence Based on Sentinel 1 Data in the Coastal City of Pekalongan, Central Java, Indonesia

Sea level rise is a pure impact of climate change. However, the process of studying sea level rise must include local factors that influence such as land subsidence. This study focuses on sea level rise using the CEEMDAN method and land subsidence using the DInSAR method. The location of this research is Pekalongan, Central Java, Indonesia. Tidal data used in this study was for five years, from 2016 to 2020, obtained from the Geospatial Information Agency (BIG). Then the data used to study land subsidence in this study uses Sentinel-1 Synthetic Aperture Radar (SAR) data in 2015, 2016, 2017, and 2020. Pekalongan is an area with mixed diurnal tidal types with Formzahl number 1.7. The sea level rise in Pekalongan is relatively high, at 10.6 mm/year. Then the land subsidence that occurred in Pekalongan is the phenomenon that has the most influence on the occurrence of coastal flooding in the region. The average land subsidence on the coast of Pekalongan is 5.37 cm/year. In addition, the sampling results in 6 areas showed that the most significant decrease was in Area 2, with a decrease of -7.91 cm/year. Based on this research, land subsidence is the most considerable influence on flooding in Pekalongan compared to sea level rise.

Technoeconomic evaluation of offshore green ammonia production using tidal and wind energy: a case study

ABSTRACT The climate crisis is driving policy makers, energy companies and chemical industries to accelerate the transition from conventional high-carbon ammonia to low-carbon and zero-carbon (green) ammonia. Ammonia is produced on a vast scale globally and is predominantly used for fertilizers but has a potential use as an energy vector. Utilizing variable renewable energy (typically solar or wind) for green ammonia production requires expensive energy storage. Tidal stream energy is a novel energy source for green ammonia production and could be an ideal energy source given its high resource availability and predictability. The objective of this paper is to determine if tidal stream energy is a useful energy resource (technically and economically) for offshore green ammonia production. This idea is presented through a case study on the Pentland Firth, a globally excellent tidal stream location. Using 30 years of hourly wind and tidal data, the addition of tidal stream capacity to wind capacity is shown to decrease the hydrogen storage requirement by 96% and eliminate the fuel cell requirement and thus reduce the levelized cost of ammonia (LCOA) by 12%.

Preliminary study on saltwater distribution of lowland area at West Coast, Johor Malaysia

Saltwater intrusion is a severe concern in coastal locations that pose a threat to the groundwater environment. Climate change, tidal effects, and groundwater exploitation all have the potential to disrupt the balance of salt water and fresh water in coastal aquifers which is the result of seawater intrusion that included the studies area. The sea-level rise is regarded as a cause that can enhance saltwater interface inland migration. Therefore, the purpose of this study is to assess saltwater intrusion in a zone mapping through the open channel distribution. This is qualified for monitoring a saltwater intrusion around West Johor which is approximately 10 km especially Batu Pahat, Johor such as Parit Botak, Parit Hailam Laut, Kampung Bahru Laut, Kampung Sri Pantai, and Sungai Senggarang. The salinity parameter was measured by the refractometer salinity instruments in percentage units (ppt) to PSU units. The high and low tides data collection on-site was monitored and analyzed saltwater intrusion distributed data into the interface mapping by using ArcGis 10.8 software. As the result, Kampung Sri Pantai was the highest data in the saline test 3 PSU for high tides and 4 PSU for low tides. However, the saltwater intrusion mapping was distributed through saline data obtained from the display maps to monitor the value of saline water in the study area. The contribution of this study to the community can be maintaining the ecosystem and monitoring existing structures such as tidal water gates and bunds of clean water resources for communities and irrigation purposes.

ANALYSIS OF THE TYPES AND CHARACTERISTICS OF THE TIDES USING THE ADMIRALTY METHOD ON TWO RIVERS IN THE KUBU RAYA DISTRICT

A study of the tides in the river has been carried out in this paper. The rivers studied are the Jawi River (Kakap) and the Nipah River. The two rivers are located in Kubu Raya Regency, West Kalimantan. This study aims to determine the type of tides and water level elevation in the two rivers. This study uses the Admiralty method to analyze existing tidal data. This method is commonly used in tide analysis. The results show that the tidal type of the Jawi River is a diurnal tide. The water level in the Jawi River is HHWL of 1.4 m (+0.86 m from MSL) and LLWL of –0.319 m (-0.859 m from MSL). Meanwhile, the tidal type of the Nipah River is a mixed tide prevailing diurnal. In addition, the water level is HHWL of 1.167 m (+0.82 m from MSL) and LLWL of –0.473 m (-0.82 m from MSL). This study is expected to be helpful as a reference for infrastructure development in the research area.

MultiscaleDTM: An open‐source R package for multiscale geomorphometric analysis

AbstractDigital terrain models (DTMs) are datasets containing altitude values above or below a reference level, such as a reference ellipsoid or a tidal datum over geographic space, often in the form of a regularly gridded raster. They can be used to calculate terrain attributes that describe the shape and characteristics of topographic surfaces. Calculating these terrain attributes often requires multiple software packages that can be expensive and specialized. We have created a free, open‐source R package, MultiscaleDTM, that allows for the calculation of members from each of the five major thematic groups of terrain attributes: slope, aspect, curvature, relative position, and roughness, from a regularly gridded DTM. Furthermore, these attributes can be calculated at multiple spatial scales of analysis, a key feature that is missing from many other packages. Here, we demonstrate the functionality of the package and provide a simulation exploring the relationship between slope and roughness. When roughness measures do not account for slope, these attributes exhibit a strong positive correlation. To minimize this correlation, we propose a new roughness measure called adjusted standard deviation. In most scenarios tested, this measure produced the lowest rank correlation with slope out of all the roughness measures tested. Lastly, the simulation shows that some existing roughness measures from the literature that are supposed to be independent of slope can actually exhibit a strong inverse relationship with the slope in some cases.

Accurate water level predictions in a tidal reach: Integration of Physics-based and Machine learning approaches

Accurate water level prediction is very important for coastal construction and flood prevention in an estuarine area. However, it is challenging to represent the water level processes accurately in a spatial domain due to the dual influences of river discharge from the upstream tidal reach (upstream discharge) and astronomical tides. In this study, a new method is proposed to predict water levels in tidal reaches by developing a riverine-estuary Hydrologic-Hydrodynamic Coupling model (H2C) and integrating the outputs (Upstream discharge and water levels, tidal levels) with long-short term memory. Then, the relative contribution of upstream discharge to water level predictions is assessed by extreme gradient boosting. The coupling model (H2C-XL) is driven by basin-scale Satellite-derived Meteorology Estimate datasets and TPXO9 tidal data. H2C-XL is tested in a tidal reach (Tianhe-Zhuyin reach) and found to be effective in enhancing the accuracy of water level predictions dramatically. The Nash coefficient and Kling-Gupta Efficiency values of predicted upstream discharge are 0.866 and 0.922, respectively. Accurate upstream discharge prediction is crucial for water level predictions in tidal reaches. This is reflected in that the Nash coefficient and Kling-Gupta Efficiency values are up to 0.781 and 0.806 for predicting water levels at upper hydrologic stations (Jiangmen and Daao stations), which are improved by 12.34% − 40.46% and 16.98% − 32.34% than those of above models. The relative contribution of upstream discharge to water level predictions in Tianhe-Zhuyin reach ranges from 0.37 to 0.55. The values vary at the same site depending on the hydrologic conditions each year and are relatively low near the coastline, but nonlinearly increase with the distance from the coastline.

Tide2Topo: A new method for mapping intertidal topography accurately in complex estuaries and bays with time-series Sentinel-2 images

Intertidal zones serve as a critical transition between land and ocean and are periodically inundated by tides. They are extremely important to coastal communities as it provides diverse habitats and buffers against marine hazards. However, the reduced river sediment together with sea level rise and coastal reclamation have caused the widespread loss of intertidal areas. Reliable, high-resolution, and up-to-date intertidal topography maps are key information for coastal vulnerability assessment and restoration. Existing approaches to intertidal topography reconstruction involve significant ground surveys, with limited spatial coverage, accuracy, and efficiency, thus, restricting their potential to generalize globally. To address these issues, we propose a pixel-based approach to construct intertidal topography from dense Sentinel-2 satellite time-series and limited ground truth surveys, named as Tide2Topo. Tide2Topo differs conceptually from the widely used waterline method since it considers tidal inundation frequency as a topographic indicator rather than instantaneous waterlines. Therefore, Tide2Topo does not involve manual selection of images at different tide levels. The relationship between intertidal inundation frequency and elevation is calibrated using linear and polynomial models based on a few transect measurements instead of tidal height, preventing errors introduced by inaccurate tidal data. The proposed Tide2Topo was applied and validated in the UK and China over several complicated estuaries and bays with extensive muddy flats or sandy beaches. The results demonstrated that the topography derived from intertidal inundation frequency compared to LiDAR or UAV photogrammetric observations has a root mean square error ranging from 16 to 38 cm. The large errors were found in the tidal channel areas where the inundation frequency calculation was prone to uncertainty. Dense Sentinel-2 time-series observations ensure finer sampling of the tidal cycle, thereby not only eliminating errors caused by spatial interpolation but also maintaining the accuracy of elevation estimations at pixel level. Tide2Topo is a robust, portable and rapid method that is well suited to large-scale intertidal topography reconstruction. Future work could use Sentinel-1 SAR as an alternative data source for Tide2Topo, realizing seasonal or annual monitoring of intertidal geomorphological changes.

Analysis of Characteristics of Tide and Tidal Current in the east China Seas

The features of tide and tidal current in the east China seas were studied by the FES2014 tide data and tide gauge station data. It is found that FES2014 data is in well agreement with the observation. Among the four major tidal components (M2, S2, K1, and O1), M2 is the strongest tidal component with the maximum amplitude (tidal current) exceeds 100 cm (100 cm/s), followed by S2 tide with its maximum amplitude (tidal current) reaches 60 cm (50 cm/s). The results indicate the east China seas are dominated by semi-diurnal tides. There are four amphidromic points for semi-diurnal tides, and two amphidromic points for diurnal tides. Rotating tidal current dominates the areas far from the coast, and rectilinear current dominates the coastal sea area. The strong tidal currents are often distributed in some places with special topography such as bays and estuaries.

Analysis of Interaction Between Atmosphere and Sea Using The Delft3D Hydrodynamics Model for Mapping Coastal Flood Zone at Belawan Port and Coastal

Belawan port and coastal areas were also not spared from the impact of the tidal flood. This study aims to determine the performance of the Delft3D hydrodynamic model in simulating sea level and waves in tidal floods at Belawan port and coastal area. Final operational global analysis data, MSLP data from NOAA/NCEP, and tidal data from ECMWF were used to run the Delft3D model. The model output was verified by using tide gauge observation data from BIG (Geospatial Information Agency). This research resulted in a mapping of areas affected by tidal flooding in the Belawan port and coastal area by analyzing the interaction between atmosphere, consisting of wind speed and direction parameters and sea parameters in the form of significant wave height. Based on the results of the Delft3D verification with observation data, the average error value is 23.5 cm and the coefficient of correlation is 0.93. This shows that the Delft3D model is quite good at simulating tidal flood heights in the Belawan port and coastal area. Based on atmospheric analysis, it does not really affect the increasing wave height. The influence is given by significant sea wave height, which can increase the height of tidal floods.

Simulation of High Wave Inundation at Payangan Beach Using Delft3D for Coastal Mitigation

The south coast of Indonesia has a high risk of high waves. The community around Payangan Beach was one of those affected by the high waves, which caused damage to various buildings and inundation. One of the disaster mitigations to reduce the impact that occurs is to do inundation modeling. This study aims to model inundation due to high waves on Payangan Beach using Delft3D software. Wind, bathymetry, and tide data are used as model input data. The model was created using Delft3D-FLOW for tides while Delft3D-WAVE for waves. After the program is executed, the height and area of the inundation and significant wave height will be obtained. The modeling results will be validated with existing condition data using the Root Mean Square Error (RMSE). The modeling results show that the inundation height is 1.96 meters, the significant wave height is 2.45 meters, and the inundated area is 300 meters from the coastline, with 100 houses potentially inundated with an area of 187.4 m2. The validation results show that the model is quite good, with an accuracy of 96.88%. From these results, the Government of Jember was able to make a mitigation map for the inundation area on Payangan Beach and build a Sea Wall. So that in the future, high-wave disasters can be minimized.

Estimating paleotidal constituents from Pliocene “tidal gauges”—an example from the paleo-Orinoco Delta, Trinidad

The Neogene Orinoco Delta is one of the typical river deltas where both the records of modern and ancient tidal processes can be studied. A ∼5 m.y./>10-km-thick succession on the island of Trinidad contains remnants of paleo-Orinoco deltaic deposition preserving both tide- and wave-influenced delta lobes within the same time intervals, just like the modern Orinoco Delta that has both wave-dominated and tidal-dominated lobes. The tide-influenced delta lobes and estuaries preserve some spectacular tidal bedding signals, including tidal rhythmites. The tidal record encoded within the tidal rhythmites is preserved well enough that the primary tidal constituents responsible for the tidal currents that deposited the rhythmic facies can be inferred. Lower to upper Pliocene tidal rhythmites were examined in two main paleo-Orinoco sub-environments: (1) estuarine and delta lobe deposits of Morne L’Enfer Formation at Erin Bay, and (2) abandoned tidal channels associated with tide-influenced delta-front deposits from the Telemaque Sandstone Member of the Manzanilla Formation at Matura Bay. Both wave- and river-current signals are also present in most of the study areas. Tidal constituent analysis of unusually well-preserved paleo-Orinoco tidal rhythmites reveals a hierarchy of tidal signals that include semidiurnal, diurnal, fortnightly (neap−spring), monthly (perigee−apogee), semi-yearly, and possibly seasonal and yearly cycles that span thickness intervals ranging from millimeters to meters. The tidal constituents were dominated by, in decreasing importance, M2, S2, and likely K1 rather than O1. The modern tidal data clearly show that K1 is more important in terms of tide-generating potential than O1, as was likely so in the Pliocene. In both the rock and modern records, N2 is more significant than O1, P1, and K2 in terms of tide-generating potential. The comparison between the constituent analysis of the ancient tidal record and the modern tidal measurements reveals their similarities in tidal patterns and constituent types. From this, we deduce that the tidal constituents responsible for the Pliocene Orinoco Delta tides were mixed semidiurnal tidal cycles similar to those found today in Trinidad (Atlantic type of synodically dominated) rather than the Caribbean (tropically dominated) type.

Tidal analysis and prediction based on the Fourier basis pursuit spectrum

The high-precision prediction of ocean tides is important for coastal management. Traditional harmonic analysis (HA) regards tides as the cumulative motion of multiple trigonometric functions, ignoring the time-varying characteristics of harmonic constants. Although the time-frequency transformation method can reconstruct the time-varying characteristics of tides, there are problems with tidal component coupling and edge effects. Therefore, we propose a method of reconstructing tidal components based on Fourier basis pursuit (FBP) spectral bandpass filtering (FBPBPF) by combining the Fourier dictionary and the basis pursuit algorithm and apply this method to four tide stations in the Gulf of Maine and Hong Kong station to try to solve the above two problems. The results show that the FBP spectrum can effectively identify and separate the main coupling tidal components. In the Gulf of Maine, FBPBPF can use shorter tide data to obtain better or equivalent prediction results than HA. Especially within 30 days, the prediction accuracy of FBPBPF at the four sites can be improved by 53.5% on average compared with that of HA. At Hong Kong station, FBPBPF has higher prediction accuracy than HA and Inaction Method (IM) in 4 months, but its long-term accuracy is gradually reduced (including all stations). We believe that the frequency resolution is the key factor leading to the divergence of long-term prediction errors.

ANALISIS KEBUTUHAN FASILITAS PERAIRAN PADA PELABUHAN KUSAMBA, DESA PESINGGAHAN KABUPATEN KLUNGKUNG

Klungkung Regency has a growing tourism attraction because it has a very exotic archipelago, namely Nusa Penida, Lembongan and Ceningan Islands. So that it requires adequate crossing facilities, the Regional Government of Klungkung Regency plans to build this Kusamba Port. With this function, port development must be accountable both economically and technically. The purpose of this study was to determine the area of the construction of water facilities and to determine the needs of water facilities at the Kusamba port in Pesinggahan Village, Klungkung Regency.This research uses a quantitative descriptive method that is aligned with research variables that focus on actual problems and phenomena that are happening in the form of research results in the form of numbers that have meaning.

The results of calculating the need for water facilities at the Kumba port in Pesinggahan Village are a 140.00 m rotating pool, 1.126 km2 shipping channel, 5.170 km2 berth area, 2645.163 m2 ship berth area, 39677.445 m2 ship mooring area, 39677.445 m2 area where the ship is needed emergency 5,170,617.695 m2. So that the area of each water facility is obtained.

A multidisciplinary investigation of Storms Ciara and Dennis, February 2020

High magnitude storms have periodically impacted the communities of Western Britain and this storm threat is predicted to increase with climate change. Understanding the factors that contribute to storm catastrophe is essential to mitigate the effects of future storms. This multidisciplinary study collectively analyses meteorological, tidal gauge and newspaper data from Storms Ciara and Dennis in February 2020 to assess the environmental, social and political impacts and causes of the catastrophe in Western Britain. The analysis shows that although the storm period comprising Ciara and Dennis was a meteorological climate anomaly and short-term local authority and community responses were effective, shortcomings in governmental policies likely enhanced storm impacts. The study findings suggest that substantive changes to UK government coastal and fluvial management policies and the wider long-term climate change strategy are required to address climate change risk and reduce community storm vulnerability in Western Britain. The key roles of the media in enhancing public hazard preparedness and raising awareness of the impacts of climate change catastrophes and the wider climate crisis are exhibited. A multidisciplinary mixed methods analysis combining quantitative meteorological and tidal data, qualitative newspaper data and peer-reviewed research is shown to identify the likely cause of catastrophe and can inform future climate change vulnerability mitigation.

ROB ANALYSIS ON THE COAST OF SEMARANG CITY (CENTRAL JAVA, INDONESIA) ON MAY 23, 2022 BASED ON TIDAL DATA AND INUNDATION DISTRIBUTION

The coast of Semarang City every year always faces flood and tidal problems. Flooding is generally caused by the ongoing rainy season, while tidal flows are caused by rising Java sea levels before the interseason change. This study aims to find the relationship between the tidal incident on May 23, 2022 on the coast of Semarang City with the tidal pattern at the Port of Semarang, and find out the distribution of tidal flows based on the height of inundation in the coastal area of Semarang City. The material used is daily tide data on May 23, 2022, monthly tide data April-May 2022. Data on the distribution of high inundation was obtained based on field surveys and interviews. The results showed that the peak of java sea level elevation occurred on May 23, 2022 with an altitude at the tide staff of 210 cm. Rob occurs almost evenly along the north coast of Semarang City with different heights. The largest tidal height occurred in the Semarang Port Area, which reached a puddle height of 100 cm. There are supposes that the amount of inundation at the site is related to the land subsidence at the site that continues to occur.

Study of Hydrodynamic Patterns of Tanjung Pasir Banten Waters to Support the NCICD Sea Wall Development Plan

Numerical modeling of hydrodynamics (HD) around the Tanjung Pasir Waters was carried out using MIKE 21 HD Flexible Mesh software to get the current velocity pattern conditions during the west and east monsoons. This activity is to support the NCICD sea wall construction plan. In addition, the results that will be obtained in this modeling are the conditions of the speed and direction of the current in various tidal conditions during spring and neap. The data used in this modeling include wind speed and direction, wave height, wave period, and wave direction. Based on the research that has been done, the validation value of Naotide tidal data on tidal field data is 93.8 %. HD MIKE 21 modeling results on field data have a validation value of 93.4 %. Extract points 4 and 5 which are the northernmost, have the highest current velocity values compared to the other points. In addition, when heading to the high tide phase, both spring and neap conditions, the current velocity value has the highest value.

Adaptation timescales of estuarine systems to human interventions

Many estuaries and tidal basins are strongly influenced by various human interventions (land reclamations, infrastructure development, channel deepening, dredging and disposal of sediments). Such interventions lead to a range of hydrodynamic and morphological responses (a changing channel depth, tidal amplitude and/or suspended sediment concentration). The response time of a system to interventions is determined by the processes driving this change, the size of the system, and the magnitude of the intervention. A quantitative understanding of the response time to an intervention therefore provides important insight into the processes driving the response. In this paper we develop and apply a methodology to estimate the response timescales of human interventions using available morphological and hydraulic data. Fitting an exponential decay function to data with sufficient temporal resolution yields an adaptation timescale (and equilibrium value) of the tidal range and deposited sediment volumes. The method has been applied in the Dutch Wadden Sea, where two large basins were reclaimed and where long-term and detailed bathymetric maps are available. Exponential fitting the morphological data revealed that closure of a very large part of a tidal basin in the Wadden Sea initially led to internal redistribution and import of coarse and fine sediments, and was followed by a phase of extensive redistribution while only fine-grained sediments are imported. Closure of a smaller part of a smaller basin led to shorter response timescales, and these response timescales are also more sensitive to rising mean sea levels or high waters. The method has also been applied to tidal water level observations in the Scheldt and Ems estuaries. Exponential fits to tidal data reveal that adaptation timescales are shortest at the landward limit of dredging. The adaptation time increases in the landward direction because of retrogressive erosion (Scheldt) or lowering of the hydraulic roughness (Ems). The seaward increase in adaptation time is related to the seaward widening of both systems.

INTERPRETATION OF CURRENT AND TIDAL PATTERN AT SELANGOR RIVER, KUALA SELANGOR

Abstract. Tidal data has been used to determine long-term water level alterations. Tides are high-powered and notoriously hard to ascertain. Tidal analysis and prediction need substantial study with the requisite approaches, techniques, and tools in conjunction with weather parameters and natural calamities. TOtal TIde Solution (TOTIS) software, which is rooted in harmonic analysis, is one of the most often used software in Malaysia. This study aims to interpret the current circulation and tidal pattern at the Selangor River, Kuala Selangor, Selangor Darul Ehsan. A period of one-month data is retrieved via Valeport 740 Tide Gauge from tide gauge station, whereas the current data are retrieved via Valeport Current Meter 105, which are used to analysed. The latest updated data period for the tide gauge station utilised are based on the availability of data. Therefore, tides are predicted using 33 resolved constituents for two years, starting from January 2021 until December 2022. Tidal analysis generates tidal constituents, which are then used for tidal prediction. Root Mean Square Error (RMSE) and datum offset are used to evaluate software's output. It signifies that TOTIS software is trustworthy and reliable in terms of tidal analysis and prediction accuracy. The highest river current records with high speed occur during high tide phenomenon. The output data for magnitude of river current speed are derived satisfactorily with high precision. It aids in monitoring and analyse of an appropriate method to prevent or reduce additional river erosion.
