Time lapsed Satellite Imagery data for the years 2003 to 2019 along the Sindhudurg coastal tract have been used to decipher the decadal scale shoreline changes along the Indian West Coast margin. The sea level changes marked by shoreline are the artifacts of meteo-marine processes including the long duration changes in tidal and wind currents, long...

Changing climate and land-use practices influencing the natural stream flow processes in the Naryn river basin of Kyrgyzstan. Variations in stream flow regime over 33-years (1980 to 2012) were investigated using daily discharge data of three hydro-stations (Naryn, Ych-Terek and Uzunakmat), located in the Naryn River Basin. Mean monthly discharge (M...
Article
Long-term discharge variability assessment in the river channels helps to improve the water management strategies under the changing climate change scenarios. The present study investigated the 40-year (1970–2010) spatio-temporal variability in the discharge of the Krishna and Koyna River channels at Karad and Varunji gauging stations. Mean annual...

Historical records claim Marakkanam, in Tamil Nadu, India, to be a flourishing port having commercial ties with the Greeks and Romans. Marakkanam is a coastal town touching the Bay of Bengal. However, this place now reveals traces of estuarine and lagoonal characteristics, far removed from being an actual port. The satellite-derived Remote Sensing...

Climate change and associated factors such as global and regional sea-level rise; the upsurge in high-intensity flooding events; and coastal erosion are pulse and press disturbances that threaten to increase landslides in coastal regions. Under these circumstances; a rigorous framework is required to evaluate coastal vulnerability in order to plan...

Detection and delineation of Water Body Area (WBA), particularly over inaccessible hilly region is not always possible in view of time, resources and cost issues. An automated procedure for detection and delineation of water bodies in the hilly region was performed using satellite-derived DEMs. CartoDEM, SRTM and ASTER GDEM data with 30, 90 and 30m...

The disposals of municipal solid waste (MSW) in open dumps are a widespread activity around the vicinity of urban area. When rainwater interacts with dumping yards, generate a leachate and percolates through the soil strata and after particular time they pollute the groundwater and soil in the vicinity. In view of this, assessment of soil fertility...

Spatio-temporal variations in water availability are foremost attribute of the majority of river basins, especially in semi environment. Several tasks and schemes have been implemented to overcome the gap between water supply and demand. Unfortunately, most of schemes and tasks are failed due to reduced water retention capacity of the same basins a...

The Koyna-Warna area in Maharashtra, Western India, is one of the world’s best examples of reservoir-induced seismicity. The occurrence of earthquakes in the vicinity of Koyna Dam (Shivaji Sagar Lake) started since 1962, soon after the initiation of water impoundment. To understand the tectonics and seismicity of the region, recent Landsat 8 images...
