Estimation of soil erosion and sediment yield in Wadi El Hachem watershed (Algeria) using the RUSLE-SDR approach

Spatial modeling of soil loss as a response to land use-land cover change in Didessa sub-basin, the agricultural watershed of Ethiopia

“…The highest soil erosion rates have occurred in the western areas of the country due to the combination of the high amount of rainfall and poor traditional farming practices in the steeper topographic position and poor vegetation cover [ 33 ]. However, studies confirmed natural vegetation cover cleared for farming intensification was acknowledged as a trigger of soil erosion problems which finally resulted in the collapsed natural economy [ 9 , [34] , [35] , [36] , [37] , [38] , [39] ]. In line with this, soil erosion assessment studies have been anticipated to charge the country nearly two billion US$ over the past decades [ 40 ].…”

Water induced surface erosion risk assessment in Jumar agricultural watershed, Jharkhand, India using multivariate statistics and GIS

“…The current study shows that metals like sodium (seasonal average of 77 mg/l) and potassium (seasonal average of 37 mg/l) are in higher amounts in all seasons in the water bodies that are above permissible limits of 20 mg/l and 12 mg/l, respectively. This makes the water unsuitable for irrigation and drinking purposes (Saoud & Meddi et al, 2023).…”

“…• Seasonal Correlation analysis of soil and water quality indicates that surface erosion occur due to geochemical processes and variations in moisture content. Water induced surface erosion is a geological process in which varying layers of soil surface get removed by the prolonged concentration of water flow (Saoud & Meddi, 2023). In Jharkhand state of India, water-induced surface erosion is a significant problem in the hilly areas of the state, especially in the districts of Ranchi, Gumla, Simdega, and Latehar district (Rafique et al, 2022).…”

“…These areas are characterized by steep slopes and loose soil, which makes them highly vulnerable to erosion. The major drivers of water induced surface erosion are rainfall, Land use land cover (LULC), topography, soil structure and type, while soil and water quality parameters act as major indicators (Bid & Siddique, 2019;Saoud & Meddi, 2023). Surface water gets deteriorated by sedimentation, heavy metal pollution and nutrient contamination which reduces the productivity of water retaining structures, enhances the water treatment cost, increases chances of eutrophication, and decrease the life of reservoirs (Kolahchi and Jalali, 2007;Lucas-Borja et al, 2019;Bid and Siddique, 2019;Chaudhari, 2020).…”
