The rainfall over the country is primarily orographic. The uncertainty of occurrence of rainfall marked by prolonged dry spells and fluctuations in seasonal and annual rainfall is a serious problem for the country. This necessitates the redistribution of the water for the betterment of the whole nation through the massive task of Interlinking of rivers. The preliminary planning of this task may take a longer time. This can be simplified and made economical by the use of latest technologies such as GIS and Remote Sensing. GIS and Remote Sensing technology have capability to provide necessary physical input and intelligence for preparation of base maps, formulation of planning proposals and act as monitoring tool during implementation phase. Satellite imageries help to maintain truthful record of terrain during that period. The decision based support system and the querying can be effectively done through GIS. Moreover the Digital Elevation Model (DEM) and the Digital Terrain Model (DTM) enables us to have a visualization of the entire project. The objective of the paper is to explore the capabilities of GIS that will be very useful in solving the various technical, environmental, socio-economical and political issues of interlinking in order to expedite the process of interlinking.
India is blessed with abundant water resources, which are unevenly distributed in space and time. When one part of the country is reeling under severe water scarcity, floods damage another part. India experiences extremes of climate within the 329 M ha of geographical area. Mean annual rainfall varies from 100 mm in western Rajasthan to over 11000 mm at...
