Abstract
As a part of the National Water Development Authority (NWDA) proposal, the linking between Pennar and Cauvery is put forth with a single purpose of conserving water to the maximum extent possible. The present study covers with land use/land cover (LU/LC) along the alignment study area 17215.68 sq·km. All the details of these features have been studied using IRS-P6, LISSIII data to analyze the effect of land use and land cover. The land use and land cover data are classified into 9 categories such as crop land, current fallow, forest, plantations, built-up land, water bodies, scrub land, sandy area and others. The total area going to be capsized is 17215.68 sq·km out of which 10105.96 sq·km is proposed command area. The 244 villages have to be rehabilitated due to this canal whereas about 4597 villages will enjoy the fruits of this canal in the form of drinking water, ground water recharge and as an additional source of irrigation as well. The study indicated current fallow land of 5340.14 km2 and 6307.98 km2 of cropland can be brought under cultivation which is more than what NWDA estimated land that can be benefitted.

The visual interpretation has been carried out based on the data acquired from standard FCC (False color composite) imagery of IRS-P6, LISS-III for land use and land cover
Summary
In today’s world, water has become a very vital ingredient for the sustenance of life on the planet earth. Places where water is surplus suffer from floods and from droughts and famines where water is scarce Under such conditions, it was conceived that if water could be transferred from one basin to another, it may prove to be of greater use to meet the demand for water, in urban areas. Many investigations were done with Remote Sensing & GIS inputs for studying various land features and the changes Lo [31], Raghava Swamy et al [32], Civco [33], Rao et al [34], Murthy & Venkateswar Rao [35], Weicheng Wu et al [36] This information is vital to oversee, design the Land use and for detecting the changes in the environment as well. The areas under each of the branches so measured were adjusted to match with the gross command area of 840,218 ha after deducting the forestland
