Abstract

Objectives: The quantitative morphometric analysis is found to be vital study in understanding hydrological aspects and its interaction with the environment of any watershed system. The main objective of the study is to calculate the morphometric parameters of the Barhar river watershed. Methods/Statistical Analysis: The study area lies between 79° 32′ E to 79° 37′ E longitude and 25° 22′ N to 25° 30′ 30′′ N latitude covering an area of about 48.75 km2 belonging to Bundelkhand region. The drainage of the region has been prepared using Survey of India (SOI) toposheet (No.54O/11), Landsat TM and Digital Elevation Model (DEM) of the area. Remote Sensing (RS), Geographical Information System (GIS) and Global Positioning System (GPS) have been used in the study as efficient tools in our various modern geographical and geological studies. Findings: Barhar river watershed belonging to the northern part of Mahoba district is a hard rock terrain consisting mostly granite and granitoids. Rivers flowing in such terrains are mostly found to follow the fractures and lineaments. The watershed is of forth order drainage having drainage density and stream frequency of 2.281 and 2.481 respectively. The watershed shows elongated in nature. The method applied to the river basin gave a recent calculation of the morphometric parameters of the region. Application/Improvements: The drainage morphometric analysis is important in selection of water recharge sites, watershed modelling and groundwater prospect mapping. The study would provide an important information collection regarding future watershed prospects of the area.
