Design And Management Of Mettur Dam By Predicting Seepage Losses Using Remote Sensing

ABSTRACT In dam safety assessment, it is customary to focus on stability analysis, and the safety factor is regarded as an assessment index that cannot correctly reflect the effect of multi-factors and variable uncertainty. The factors that induce dam breaks are complex and uncertain; however, three primary ones can be identified: hydrological factors, seepage and bank slope instability. In this paper, the risk probability and the dam break threshold value for each factor individually, as well as coupled factors, are studied. The threshold value is acquired using the relationship formula between risk probability and dam type. In our project we are discussing about the details of Mettur dam in Tamilnadu. In this study the seepage losses calculating methods and prevention techniques also adopted.
