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.

位于 Shivalik 山上的上部 Patiala-Ki-Rao 流域的土壤侵蚀脆弱区的优先级

在本研究论文中，对位于印度旁遮普邦 SAS Nagar 区 Shivalik 丘陵和印度哈里亚纳邦 Panchkula 区的上部 Patiala-Ki-Rao 流域进行了形态测量分析和优先排序。形态测量参数分为三类，例如线性、面积和浮雕方面。遥感和地理信息系统 (GIS) 用于量化这些形态测量参数以及水位测量和侵蚀积分，以了解流域特征。准备土壤、坡度和土地利用专题图层，并在 GIS 叠加技术的帮助下，使用 Saaty (1980) 提出的层次分析法 (AHP) 根据优先级确定侵蚀脆弱区域。根据对土壤侵蚀的相对敏感性，这些专题层被赋予权重，并被赋予其中的类别。根据目前的研究，选定的流域最终被划分为易受侵蚀的高、中和低优先级区域。本研究的结果有助于决策者根据侵蚀的严重程度来规划相关的水土保持技术。
