Abstract :
Various factors like geology of the area, soil type, hydrological setting of the area etc. have an impact on drainage basin characteristics. Morphometric study of these features of a particular area is helpful to throw light on, geomorphological features, lithology, structural features, and ground water conditions of the area. Lineaments and hydrological setting of the area which in turn throws light on ground water conditions and movement of groundwater. The study area is Kumbhi River Basin. The study area is bounded by latitudes 16° 28' 20.77"N to 16° 44' 0.35" N and longitude 73°07' 13.74" E to 74 °49' 31.91" E on Survey of India (SOI) toposheet numbers 47H/14, 15 and 47L/2. Morphometric analysis has been carried out. Kumbhi River Basin is of 6th order. There is total 1571 streams. The Rb value of Kumbhi River Basin indicates minimum structural disturbances. The basin has coarse texture and elongated shape Hence runoff is high and infiltration is low. These low values of rho coefficient indicate that the basin is likely to be less affected during the time of floods and elevated discharge. The relief of the basin is moderate to high and it indicates low to moderate infiltration rate and high run off conditions. The frequency of lineaments in the KRB indicates large number of sub-surface openings which can act as conduits for underground water. The area has moderate to good groundwater potential.
