Morphometric Analysis of the Hasdeo Subbasin Using Alos Palsar Imagery

Abstract

"Morphometry" is the analysis of forms that presents a quantitative description of a landform. To assess the Hasdeo subbasin's hydrological features and water potentials based on the morphological characteristics, morphometric analysis of the Hasdeo subbasin was conducted in the current study. ALOS Palsar DEM data were used to reveal details on the Hasdeo subbasin's morphometry. Spatial information from Geographic Information Systems (GIS) was utilized to conduct the study. The linear, areal, and relief characteristics of the basin are taken into account as morphometric parameters for the analysis. The Hasdeo subbasin contains a river network that is classified as being of 6th order (according to Strahler's classification) and has a dendritic drainage pattern, according to morphometric analysis of the river network and the subbasin. The calculated values for the bifurcation ratio (1.93), drainage density (0.63), circularity (0.32), elongation (0.46), form factor (0.16), and stream frequency (43.86) were obtained in that order. This value demonstrated the subbasin's length, which results in low peak flows for a longer time, a significant danger of soil erosion, and a basin's extensive hydrographic network with numerous tributary streams that respond quickly to precipitation. Prioritizing a region based on morphometric analysis is very valuable.
