Morphometric analysis is not only important for a hydrological analysis, but also necessary in the management and development of a basin. In this study, we attempted to prioritize twenty sub-watersheds of Bamhani watershed considering the linear, aerial and relief aspects of the watershed that will be further used in the multi-criterion decision making (MCDM) analysis. ELECTRE, Vlsekriterijumskaoptimizacija I kompromisno resenje (VIKOR), and aggregate method. Remote sensing and GIS approach were employed in the morphometric analysis. Percentage of changes and intensity of change indices were used in the MCDM model validation. Based on the range of Borda/Copland model values, the sub-watershed 11 took place at the first rank, while the Compound Factor (CF) model placed in the second rank, implying to be the most susceptible sub-watersheds for erosion. Vulnerability of sub-watersheds to soil loss (erosion), the VIKOR models showed four vulnerability classifications as very high, high, moderate and low. In conclusion, our results of the morphometric studies appeared to be effective in estimating the erosion status and prioritization of the watershed concerned for the purpose of easy and early development and management of natural resources. A high reductive accuracy was observed by VIKOR in comparison to CF and ELECTRE models.

对水蚀风险敏感地区进行优先排序的多标准决策方法的可行性

形态分析不仅对水文分析很重要,而且在流域的管理和开发中也是必需的。在这项研究中,我们尝试对Bamhani流域的20个子流域进行优先排序,考虑到该流域的线性,空中和浮雕方面,这些流域将进一步用于多标准决策(MCDM)分析中。ELECTRE,Vlsekriterijumskaoptimizacija I kompromisno resenje(VIKOR)和聚合方法。形态计量学分析采用遥感和GIS方法。变化百分比和变化强度指标用于MCDM模型验证。根据Borda / Copland模型值的范围,分水岭11位于第一等级,而复合因子(CF)模型位于第二等级,暗示它是最容易受到侵蚀的子流域。对于子流域的土壤流失(侵蚀)脆弱性,VIKOR模型显示了四个脆弱性类别,分别为非常高,高度,中度和低度。总而言之,我们的形态计量学研究结果似乎可以有效地估计相关流域的侵蚀状况和优先次序,以便于自然资源的早期开发和管理。与CF和ELECTRE模型相比,VIKOR观察到了很高的还原精度。我们的形态计量学研究结果似乎可以有效地估计相关流域的侵蚀状况和优先次序,以便于自然资源的早期开发和管理。与CF和ELECTRE模型相比,VIKOR观察到了很高的还原精度。我们的形态计量学研究结果似乎可以有效地估计相关流域的侵蚀状况和优先次序,以便于自然资源的早期开发和管理。与CF和ELECTRE模型相比,VIKOR观察到了很高的还原精度。
