| Abstract: | Aerial remote sensing coupled with selective field check was carried out to assess the feasibility of the Srinagar dam site, related construction works, location of Srinagar Thrust and to evaluate terrain factors that may have adverse influence on the life of the structure. The lithology of the area comprises mainly of quartzites, phyllites, basic rocks and limestones which trend WNW-ESE. The Srinagar Thrust following the regional trend passes through the centre of the area. The investigation has established the location and extension of Srinagar Thrust and other faults, and presently dormant state of Srinagar Thrust. It also links the major Kaliasaur landslide with a fault. There is a possibility that the slide would contribute a substantial amount of silt into the reservoir. |
