ABSTRACT:
The
Par-Tapi-Narmada river link envisages transfer of surplus water from west
flowing rivers between Par and Tapi in Gujarat State, India to water deficit
areas in North Gujarat. The scheme is located mainly in southern Gujarat but it
also covers part of the areas of Maharashtra, North of Mumbai on the Western
Ghats of India. The main aim of Par-Tapi-Narmada link is to transfer the
surplus waters of Par, Auranga, Ambica and Purna River basins to take over part
of Narmada Canal command (Miyagam branch) after providing enroute irrigation.
It is proposed that water saved in Sardar Sarovar Project, as a result of this
transfer, would be taken further northwards to benefit water scarce areas of
north Gujarat and also westwards in Saurashtra and Kutch regions. The construction
of seven reservoirs on Par-Tapi-Narmada River Link Project would affect land
use/land cover, settlements and infrastructure facilities within and around
reservoir area. Thus, the submergence impact analysis of all the seven
reservoirs of this project have been carried out by using remote sensing and
GIS techniques for planning and designing of the structures. Out of the seven
reservoirs, the paper discusses submergence analysis of Kelwan Dam reservoir
which is located in geologically complex region of the Dangs district. The
study attempts to assess the present problems of submergence of land, forest,
agriculture, settlements and infrastructure facilities by using GIS techniques
for taking alternative remedial measures prior and during construction of the
dams.
