Abstract

Drainage basin characteristics depends on various factors like geology of the area, soil type, hydrological setting of the area etc. Study of morphometric characters is helpful to know more about lithological structures, geomorphological features and conditions, lineaments and hydrological characteristics of the area which in turn throws light on ground water conditions and movement of the area. Study area is Pattankodoli Nala Basin, bounded by latitude 16°36'31'' N to 16°40'44'' N and longitude 74°18'37'' E to 74°22'39'' E in Survey of India (SIO) Toposheet numbers 47L/6 on the scale 1:50000. Morphometric analysis has been carried out and various morphometric aspects have been studied. On the basis of quantitative analysis of morphometric parameters, it found that the Pattankadoli Nala is 4th ordered and the whole river contains 50 streams. The low drainage density and low stream frequency indicates that the drainage nala has less runoff in the channel. The basin is having elongated shape and gentle slope. Both relief and drainage density are low to moderate. It is found that the South Western part of the basin has moderate to good ground water potential and is favorable for artificial recharge site construction.
