Abstract
In this research paper, morphometric analysis and prioritization were carried out for upper Patiala-Ki-Rao catchment lying on Shivalik hills of SAS Nagar district of Punjab and Panchkula district of Haryana state, India. Morphometric parameters were classified into three categories such as linear, areal and relief aspects. Remote sensing and geographic information system (GIS) was used to quantify these morphometric parameters along with hypsometric and erosion integrals to understand watershed characteristics. Soil, slope, and land use thematic layers were prepared and with the help of GIS overlay technique, erosion vulnerable areas were identified based on priority by using analytical hierarchical process (AHP) proposed by Saaty (1980). These thematic layers were assigned weightage and ranks were assigned to the categories within it on the basis of relative susceptibility to soil erosion. Based on the present study, the selected watershed was finally classified into high, medium and low priority areas susceptible to erosion. The results of the present study are useful to decision-maker for planning relevant soil conservation techniques according to the severity of erosion.
