29-Delineation of waterlogging in canal command area using landsat TM data - Acase study in South Western part of Punjab.

Abstract

After the introduction of canal irrigation, large areas in South Western part of Punjab have been effected by waterlogging. An uptodate knowledge of the areal extent of the waterlogged lands is essential for formulating and executing effective management strategies. Remote sensing techniques provide quick and accurate estimation of the areas effected by waterlogging menace. The present study was undertaken to operationalize the technique of delineating waterlogged areas using multidate landsat TM images and provide an uptodate knowledge of areal extent of waterlogged lands to the State Irrigation Department for taking up suitable anti-waterlogging measures.
