In India, energy demand has increased considerably during last few decades. In order to meet this increasing energy demand sustainably, there is a need to move towards low-carbon energy sources. Himalayan water towers have a huge potential for generating clean and renewable energy. Small Scale Hydropower Projects (SHP) could provide clean and renewable energy and have a minimal impact on ecology and biodiversity. In this project, hydrological model and geospatial techniques would be used to identify hydropower potential zones for establishing small hydropower projects. A multi-criteria approach would be adopted which will integrate the geospatial and hydrological data together to identify hydro power potential zones and suitable sites locations for SHP along the stream network. Global warming has resulted in glacier retreating and snowmelt which further results in the formation of glacial lakes. These glacial lakes when breach could result in Glacial Lake Outburst Flood (GLOF) causing flash flood downstream. The GLOF hazard has become a prominent concern for harnessing hydropower potential of the Himalayan regions. Therefore, it is important to identify the hotspot, monitor the health of these lakes and estimate the potential risk associated with GLOF. Present project work would use satellite imaginary and a detailed inventory of glacial lakes would be prepared. For the detection of glacial lakes, three indexes namely; Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI) and Normalized Difference Turbidity Index (NDTI) would be used. After mapping of the glacial lakes, the vulnerability of glacial lakes would be analyzed based various parameters such as the area of lake (> 0.1km2), lake is attached with parental glaciers and/or at the snout of the glacier, steep slope, freeboard, potential flood volume, possible lowering height. The GLOF parameters such as Potential Flood Volume (PFV) and lowering height (Hp) of glacial lakes would be calculated using Steep Lakefront Area (SLA) approach. To identify the risk associated with the GLOF hydrodynamic modeling of the critical glacial lake would be done. The model would be used for the analysis of discharge, water level, water velocities and development of rating curves in the historical and future times at different section of river reach. Rural livelihoods in Himalayan regions are highly dependent on availability of water. The project would also aim to identify linkage between water use pattern and livelihood in the selected villages of the area. The project would also work towards formulating strategy for increasing the water use efficiency and capacity building of village level institutions.
