| Abstract: | The remotely sensed data provides synoptic viewing and repetitive coverage for thematic mapping of natural resources. In the
present study hydrogeomorphological mapping has been carried out in Kakund watershed, Eastern Rajasthan for delineating groundwater
potential zones. IRS-1D LISS III Geocoded FCC data in conjunction with Survey of India toposheet (1:50000 scale) and field
inputs were used for thematic mapping. Geomorphic units identified through visual interpretation of FCC include: alluvial
plain, plateau, valley fills, intermontane valleys, burried pediment, residual hills, and linear ridges. In addition, lineaments
were mapped since they act as conduit for groundwater recharge. Majority of the lineaments trends NE-SW and a few along NW-SE
directions and are confined to the southern and southeastern parts of the watershed. Based on hydrogeomorphological, geological
and lineament mapping the Kakund watershed has qualitatively been categorized into four groundwater potential zones, viz.
good to very good, moderate to good, poor to moderate and very poor to poor. The study reveals that only 10.97% of the area
has good to very good, 35.41% area with moderate to good, 49.04 % of the area has poor to moderatel, while remaining 4.57%
has poor to very poor groundwater potential. |
