Morphometric Analysis of Dhasan River Basin, Madhya Pradesh, India, Using Remote Sensing and Arc GIS Techniques

Abstract

The morphometric study of a basin is essential for a better understanding of the geological nature and groundwater conditions of that area. This study emphasizes on the identification of the types of drainage pattern determined by Arc GIS technology and computation of various parameters of morphometric analysis. The scarcity of water for irrigation and domestic purposes is the major issue in the Dhasan river area. The drainage network has been prepared from the SRTM DEM (30 m) using hydrology tools of Arc GIS 10.2.2. The GIS techniques have been used to evaluate various morphometric aspects which include linear, aerial and relief parameters. The field of research shows a dendritic drainage pattern because the entire area is a hard rock formation. The basin drainage density is 1.13, suggesting a very coarse grain texture that demonstrates homogeneous rock type and low surface runoff. This study incorporates the probability of the suitability of hydrogeological conditions that can be taken care of to use groundwater for domestic, industrial and irrigation purposes.
 HIGHLIGHTS
 
 SRTM DEM (30 m) has been used to prepare a map and to measure relief characteristics of the Dhasan basin
 Using Arc GIS 10.2.2 hydrology tools, various morphometric parameters have been computed
 Quantitative evaluation of the region helps identify the drainage network, location of the region, slope, topographic relief and other characteristics
