Morphometric Analysis and Prioritization of River Pravara to Soil Erosion Using EDAS Method
摘要
The degree of soil erosion has significantly increased as a result of the complexity of natural and human systems. As a result, in order to understand watersheds and predict future conditions using a watershed technique, a substantial spatial component must be created. It is crucial to comprehend the significant watershed areas with a history of soil erosion since these regions have issues with stream displacement and soil erosion. In order to rationalize decision-making processes with regard to the many accessible decision variables, multi criteria decision making (MCDM) approaches have been widely adopted. As a result, in this work, widely utilized MCDM approaches have been employed to rank the Pravara river sub basin according to a number of morphological features that are susceptible to soil erosion. The morphological factors, such as the linear, aerial, and relief parameters, are estimated using ARCMAP 10.8, and their potential to increase soil erosion is further examined. In order to avoid repercussions brought on by soil erosion as a result of variations in certain geomorphological characteristics, these metrics are employed as decision-making considerations. The MCDMs, EDAS, method has been adopted. The study’s findings show that sub watershed 1 is significantly more prone to soil erosion than sub watershed 6, which is less prone to erosion and undergoes accretion.
