Sediment yield (SY) is the total mass of sediment that leaves a catchment per unit of time. It is the combined result of several erosion processes (e.g. sheet and rill erosion, gully erosion, riverbank erosion, landslides) and sediment deposition (e.g. at field boundaries, on footslopes, alluvial plains, river beds) taking place in the river catchment.

Geospatial Assessment of Soil Erosion Intensity and Sediment Yield Using the Revised Universal Soil Loss Equation (RUSLE) Model

The maps generated in the study show that the area has the highest sediment yield and higher average annual soil loss, and the very high severity class represents 8%, 16% under high, 21% under moderate, 12% under low, and 13% under very low soil loss in the Chitral district.

Spatial Distribution Characteristics of Heavy Metals in Surface Soil of Xilinguole Coal Mining Area Based on Semivariogram

The results show that human activities play a decisive role in the spatial distribution of heavy metals, leading to their spatial distribution in the form of “core periphery”, which is a target for the prevention and control of environmental pollution in the study area.

Land reclamation using reservoir sediments in Tigray, northern Ethiopia

Accelerated soil erosion leads to sedimentation in reservoirs and a decline in their life span. As many reservoirs in northern Ethiopia are dry at the end of the dry season, we were able to evaluate
