Morphometric analysis of watershed based on remote sensing
and satellite derived Digital Elevation Model (DEM) are
most important data for proper hydrological investigation of
any terrain which indirectly support hydrogeological
status of the watershed. The quantitative analysis of morphometric
parameters is found to be of immense utility in
watershed delineation, soil and water conservation and their
management. The morphometric analysis carried out in the
Orr watershed shows that the basin has low relief and
elongated shape. Artificial recharge and runoff harvesting in
the area for groundwater development management are
selected based on small-scale topographic maps. Drainage
analysis makes a positive contribution through the advantage
of remote sensing and GIS-based tool in selecting artificial
recharge sites. These analyzed drainage parameters provide
comparative indices of the permeability of rock surfaces in
various parts of a drainage basin. If these information are
integrated with the other hydrological characteristics of the
drainage basin, the strategy of siting recharge and water-harvesting
measures provides better groundwater development
and management plan.
