Rehabilitation of Irrigation Tank Cascade System Using Remote Sensing GIS and GPS

Many of the irrigation tanks are interconnected forming cascades, allowing surplus flow of the upstream tanks(s) and return flow from the upstream command area(s) to reach the tank immediately downstream. This facilitates reuse of water in the command area of the downstream tank, and in effect, increases available water for irrigation. There are several problems of the irrigation tanks, such as reduction of design discharge as a result of silting of channel and tanks, deterioration of stone masonry channel, and encroachment of drainage courses and tank water spread leads to the decline of tank performance.
