The study has been carried out in the upper catchment area of Kumari river basin in the eastern part of India. The main aspiration of the study was to examine the linear, areal, and relief aspect of morphometric parameter of third order sub-basin for geo-hydrological studies, with the help of geospatial technology. Here 64 third order basin has been considered for morphometric analysis. Analysis of morphometry of drainage basin plays a significant role to understand the geo-hydrological behaviour of that particular drainage basin. The result has revealed that maximum sub-basin has highest first order stream and it decreases as order increases. Also similar result we show on stream length. From the shape parameters it was revealed that maximum sub-basins were more elongated where value was > 0.5 (Re = 0.25 to 0.49). The areal and relief parameters have been shown that maximum sub basin has high discharge of runoff in short span of time and impermeable sub-soil, hard rock material condition, moderate to low infiltration capacity, poor groundwater resource. The study exposed that morphometric analysis upon integrated RS & GIS technique is a capable tool for geo-hydrological studies. Also this type of work very useful for planning of groundwater potential areas, watershed management and environmental assessment.
