Abstract: | Water is the most important natural resource which forms the core of the ecological system. The advent of remote sensing has
opened up new vistas in groundwater prospect evaluation, exploration and management. The role of hydrogeomorphological units
in tile storage of groundwater from the Kancheepuram distict has been investigated using IRS P6 LISS-III data. The Kancheepuram
district exhibits diverse hydrogeomorphological conditions where the groundwater regime is controlled mainly by topography
and geology. The extent of various water prospectus zones in terms of percentage includes, maximum area, particularly the
north-western, and central part which is characterized by good potential occupying about 43% of total area. The moderate potential
is marked by only 35%, and is scattered along the northern and southern side of the study area, the remaining 12% is of poor
prospectus, which is falling in the coastal region of the study area. |
