Increases in the velocity and transport capacity of the overland flow lead to an increase in the size and amount of soil sediment that is carried, whereas declines in the latter cause sediment deposition. Erosion of the soil is a form of non-point source pollution that can result in the silting of rivers and the contamination of water [20; 21]. Erosion of the soil also has an impact on the normal flood discharge, as well as the service life and efficiency of hydropower facilities. Erosion of soil can be caused by a variety of factors, including both natural circumstances and human activity [22]. The geomorphology, soil type, climate, and vegetation are all aspects of nature that play a role. Construction, land development, and land use are the primary aspects of human activity that have a role. One of the most important single factor that contributes to increased soil erosion and sediment yield is changes in land use. To address the multitude of environmental problems caused by the soil sediments removed from river basins and transferred elsewhere, at the watershed scale, a complete understanding and computation of soil loss is necessary. Because more research is being carried out to enhance soil erosion models that can better estimate soil loss at watershed and basin levels, soil loss and sediment supply have become key challenges in today's world. This is because more research is being carried out to develop soil erosion models that can better estimate soil loss [8; 23]. This will make it easier to pinpoint the main areas where soil erosion is occurring, which is required in order to focus conservation efforts on achieving the best outcomes. Assessment of the erosion that happens within a watershed is necessary for determining the quantity of sediment that is moved, transported, and deposited inside and outside of the basin, which is critical for resolving a variety of environmental challenges. It is possible to obtain direct measurements of erosion in a watershed by measuring the transport of solids in the closing section over the course of multiple years [24; 25; 26]. When there is a lack of hydrometric and discharge data for a watershed, modeling is a good and proven approach that may be used to analyze the amount of erosion and discharge that occurs in the watershed [1; 5; 9]. Because of these factors, mathematical erosion models were constructed in order to forecast the degree to which erosion will occur and the amount of silt that would be produced. Since the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE), two of the most widely used and widely accepted soil erosion models, can only calculate long-term soil loss at a specific location, it is essential to use alternative erosion models that can forecast sediment yield and maximum outflow on a watershed scale [27; 28; 29]. Numerous models of soil erosion have been developed throughout the world to determine the level of soil erosion and the maximum quantity of water that can flow out of the basin outlet. The Intensity of Erosion and Outflow (IntErO) model is utilized in the research to compute the soil erosion rate and maximum outflow. This is possible due to the model's usability and capacity to process large datasets. When viewed over a shorter time frame, the negative consequences that soil erosion has on agricultural output and the ecosystem are, for the most part, invisible. Under normal circumstances, soil erosion is a continuous, progressive occurrence [9; 10; 30]. If there is no accelerated land degradation process, such as gullying or landslides, then we often do not become aware of the problems until it is either too late to do something about them or it would be prohibitively expensive to do so. The rate of soil erosion is increasing, which has consequences for agriculture and has the potential to significantly cut the expected lifespan of reservoirs. These activities may, over the course of time, alter the manner in which ecosystem services are carried out, and deplete fundamental natural resources [31; 32].
