  Evaluation of Reservoir Water-Spread Area by Various Image Classification Techniques Using Remote Sensing-A Study on Vaigai Reservoir
  Author(s): Navindiran B*
  
  This study outlines the estimation of reservoir water spread area of the Vaigai reservoir using remote sensing technique. The multi-purpose reservoirs when conducted periodical capacity surveys helps in determining the rate of sedimentation and reduction in the storage capacity. The conventional methods are hydrographic surveys wherein the water spread area is estimated and is input into the trapezoidal formula to estimate the storage capacity of a reservoir. Such methods are however time consuming, cumbersome and expensive. As an alternative, multi-date satellite remote sensing provides the water-spread area of a reservoir at different water levels in a time and cost effective manner, which can then be input into the trapezoidal formula. Traditional approaches of water spread area estimation from satellite image data include the maximum likelihood, minimum distance to mean, Mahalanob.. View more»
