Abstract
Most of the minor irrigation tanks are interconnected cascades, which allows run-off and return flow of the upstream command area to the downstream tank. This facilitates reuse of water in the command area and increases available water for irrigation. The nature has can use of water transportation to irrigation tanks, into the storage results in of storage capacity which in turn of tank performance. Rehabilitation projects have been undertaken to bring the more agriculture land under from on assured irrigation system. The prediction of water availability in a tank is in important process for sustainable use of water resources in a tank cascade system. The land use/land cover map is prepared using IRS, LISS-III resolution satellite imagery reveals water usage and demand for different development activity. The problems in drainage courses and tank catchment boundaries identified using SOI 1:50,000 scale toposheet and spatial discrepancy have been adjusted with the satellite image. This study identified issues of earthen channel, catchments and head works, area the major problems are to be restored. Remedial measures suggested to improve the tank cascade system.
