土壤侵蚀是农业土地流失的主要原因，是世界范围内的一种严重环境危害。本研究进行流域优先级使用形态参数的基础上模糊最好的差的方法（F-BWM）和GIS集成古斯鲁流域，印度。本研究从土壤侵蚀的角度出发，使用五个主要参数对研究区的子流域进行优先排序，河流频率（Fs）、相对起伏（Rr）、坡面流长度（Lo）、起伏比（Rh）和排水密度（Dd）。采用基于模糊的最佳最差多准则决策（F-BWM）方法为所用准则分配权重，并将它们组合起来以获得每个子流域的侵蚀敏感性。结果表明，从土壤侵蚀等级来看，9号、14号和5号小流域最易发生土壤侵蚀，3号小流域最不容易发生土壤侵蚀。
Soil wearing away or erosion is a chief agent of land loss in agricultural land and is regarded worldwide as a serious environmental hazard. This study performed watershed prioritization using morphometric parameters based on fuzzy best worse method (F-BWM) and GIS integration for Gusru Watershed, India. This study prioritizes sub-watersheds of the study area from viewpoint of soil erosion using five major parameters i.e., stream frequency (Fs), relative relief (Rr), length of overland flow (Lo), relief ratio (Rh) and drainage density (Dd). Fuzzy based Best Worse Multi-Criteria Decision-Making (F-BWM) Method was used to assigning weights to used criteria and combining them to achieve erosion susceptibility for each sub-watershed. Results showed that sub-watersheds 9, 14, and 5 were most susceptible to soil erosion and sub-watershed 3 was the least from the viewpoint of soil erosion ranking.
