Spatiotemporal dynamics of soil loss and sediment export in Upper Bilate River Catchment (UBRC), Central Rift Valley of Ethiopia

Elucidating the response mechanisms of hydrological and sediment connectivity to the river network structure, vegetation, and topographic features in the Jinghe River Basin

“…Lopez‐Vicente (2019) introduced the new aggregated index ( AIC ) which involves rainfall, topography, and soils, and offers benefits for assessing the temporal and spatial variation of connectivity. Compared to the aforementioned combination of weights, RUSLE has the advantage of considering multiple‐factor perspectives of vegetation, land use, rainfall, and soil, and in recognizing areas with significant sediment connectivity (Tamire et al, 2022). Therefore, building on previous studies, this research uses different weight factors to distinguish hydrological and sediment connectivity, and analyze the spatial–temporal diversity of connectivity in the Jinghe River Basin.…”

Soil erosion assessment and identification of erosion hotspot areas in the upper Tekeze Basin, Northern Ethiopia

“…However, most of the previous studies were plot-scale, or small-scale at small-watershed; and were fragmented. Recently, majority of the sub-basin and basin-based soil erosion assessments studies are conducted in Blue Nile Basin [ [26] , [27] , [28] , [29] , [30] , [31] ], and Rift Valley Basin [ 17 , [32] , [33] , [34] , [35] , [36] ], while data on soil erosion status in the Tekeze River basin in Waghimra administrative zone is scarce. Since the basin is home to millions of rural farmers whose economy mainly depends on rain-fed agriculture, estimating soil erosion rates and identifying erosion hotspot areas at basin level is critical for land and water resource management.…”
