Therefore, modeling of runoff and sediment yield at the catchment level is necessary. In this study, an attempt was made to simulate runoff and sediment yield of hydrologically similar basins of Kali River and Aghanashini River which joins west coast of India. A conceptual, continuous time and semidistributed SWAT2012 (Soil and Water Assessment Tool) model was selected for the modeling purpose. For the last two decades, Kali river basin experienced a very high rate of soil erosion due to various developmental activities in the basin. Therefore, it is essential to identify the soil loss within the basin. There are five dams constructed across the Kali river basin for various purposes. The presence of these reservoirs regulates stream flow and thus sediment load in the basin. However, the free movement of water across the Aghanashini river catchment leads to the unobstructed passage of sediments to the river mouth, as the catchment is not disturbed by the reservoir. This study deals with the impacts of the dams on stream flow, sediment load and the response of shoreline. Digital Shoreline Analysis System (DSAS) tool was used to analyze the shoreline changes. Simulated and observed values of runoff are compared, and calibration and validation were done for the basins using SWAT-CUP. Analysis of calibration and validation results shows that the model has a good performance. Therefore, the SWAT model can be used to conduct further studies in these study areas. Sediment yield obtained at the catchment outlet was 1.07 t/ha/year and 4.58 t/ha/year for Kali and Aghanashini basins, respectively. Less

Coastal zone is subjected to threats due to change in shoreline. Shoreline change leads to modification and causes for damages of properties, infrastructure around the shoreline region. These modifications, changes of land expands too many issues of the environment under the coastal zone. The present study was carried out by employing remote sensing and GIS techniques for the coastal regime of Karwar, India. LANDSAT-8 remote sensing data was integrated with the GPS data collected during the field survey. The satellite data is processed and analyzed using ERDAS IMAGINE 2014 tool and ArcGIS 10.3 tool, respectively. High Water Line (HWL) is considered for the extraction of shoreline. The visual interpretation of satellite imageries is carried out to distinguish the HWL. Net Shoreline Movement (NSM) was evaluated by adopting Digital Shoreline Analysis System (DSAS) tool. Statistical methods such as Weighted Linear Regression (W...

Destruction of the properties is the main issue in urban areas and damage to the agriculture practices in the rural area. Flood risk is rising significantly all over the globe. The regional water cycle and water resource availability are governed by the rainfall event, which is a fundamental meteorological parameter. The objective of the study is to examine the rainfall variability for 25 years from the period from 1995 to 2020 for monthly and annual rainfalls in the part of Nanjangud taluk, Mysore district, Karnataka. During the last three years that is 2017 to 2019 during the southwest monsoon, it is noted that the severity of flood increased in the surrounding of Nanjangud town, due to the heavy rainfall and excess amount of water released has augmented the inflow source of flooding. The assimilation of Remotely Sensing (RS) and Geographical Information System (GIS) is capable to generate a sequenc...

It is key geo-indicator of coastal environmental resource threats within the coastal zone. Shoreline change leads to causes for change in natural habitats, infrastructure change in the coastal zone and so on. These changes which rise to serious issues those are related to the coastal zone. The present study is carried out for the Karwar Coast, West Coast of India, using remote sensing and GIS Techniques. LANDSAT-8 remote sensing data which is available from 2013, coupled with GIS techniques used for the shoreline analysis. The acquired image was subjected to layer stacking to remove errors from raw image data using ERDAS IMAGINE 2014 tool and analyzed by ArcGIS 10.3 tool. For extraction of shoreline the High-Water Line (HWL) considered and visual interpretation of satellite imageries has been carried out to segregate the HWL, in addition to this to collect the ground truth data, the shoreline track is carried out using Trimble GPS (Global Positioning System) device. Digital Shoreline Analysis System (DSAS) were used to find rates of change of shoreline such as End Point Rate (EPR), Net Shoreline Movement (NSM). Results were concentrated on EPR as the analysis was carried for every two years from 2013 to 2017 of postmonsoon period to find out erosion and accretion. It is found to be Tagore beach is changed from accretion zone to erosion zone, and Devbagh beach is experiencing erosion. The study finds that the shoreline change is threatening to Karwar coastal zone.
