Hydrological Insights from Morphometric Analysis of the Mandovi River Basin: A Geospatial Approach

Received Date:26 February 2024, Accepted Date:27 February 2024

Abstract

The assessment of the hydrological characteristics of the surface water basin requires morphometric analysis since it is essential for comprehending the hydrological process. With the help of topographical maps and data from the Advanced Space-borne Thermal Emission and Reflection Global Digital Elevation Model (ASTER GDEM), morphometric analysis is used to ascertain the drainage characteristics of the Mandovi watershed. In this study, morphometric properties of a mountain stream at the micro-watershed level are extracted using ASTER GDEM data. Thirty micro-watersheds make up the sub-watershed. There is a Seventh-order stream in the sub-watershed. Streams dominate the sub-watershed with lower stream orders, particularly first-order streams. Slope and local relief regulate how stream segments develop. The sub-overall watershed's drainage pattern is dendritic. The sub-mean watershed's bifurcation ratio is 2.14, but its fluctuation across the different stream orders points to structural control over the growth of the stream network. The form variables reveal the sub-watershed elongation. The relief ratio reflects the sub-significant watershed's groundwater potential and high discharge capabilities. This study can aid planning techniques for the prevention of soil erosion and soil conservation.
