Land use and land cover (LULC) changes in many parts of river basins have caused water shortages, flood risks, land degradation, soil loss, biodiversity loss, and ecosystem deterioration. LULC change and topography are the main factors that cause land degradation and soil erosion in the Ethiopian highlands. The aim was to evaluate the rate of the LULC change and its effects on runoff and sediment yield in the semihumid subtropical Awash watershed using the SWAT + model. The land use maps of 2000, 2010, and 2020, along with constant climate data from 1992 to 2020, were used to investigate the effects of LULC dynamics on runoff and sediment yields. Agriculture and urbanization both increased at 7.1% and 7.95%, respectively. In contrast, the forest area decreased by 8.8% and shrubland by 3.25% from 2000 to 2020. Bare soil and urban areas covered the majority of the landscape units that were labeled as potential runoff generators. The majority of the soil erosion-prone areas that were classified as severe in the second and third scenarios covered a sizable area of urban, agricultural, and shrubland. These soil erosion hotspots covered an area of 3,777.3 ha (3.18%) and 13,413.1 ha (11.3%), with a total annual sediment yield of 361.93 m/ton and 1239.24 m/ton, respectively. In general, the change in LULC results in the annual sediment yield, with mean annual amounts of 241.8 tons/ha, 408.7 tons/ha, and 732.4 tons/ha for each scenario in the sequence. The model performance was tested using R2 = 0.88, NSE = 0.9, and PBIAS = −2.36, which indicate good agreement between simulated and observed flow, and R2 = 0.82, NSE = 0.86, and PBIAS = 4.38 for the simulated against recorded sediment yield. The increases in sediment yields have serious implications for reservoir siltation downstream of the watershed and warn land use managers to take action.

“…The SWAT + model is a QGIS extension that integrates a wide range of available geospatial data to represent the characteristics of the watershed at the hydrological response unit (HRU) level rather than the sub-basin level [ 25 ]. In the model, the impacts of spatial heterogeneity of topography, land use, soil, and slope on catchment hydrology were described in subdivisions at the watershed level [ 26 ]. The Guder catchment was divided into 33 sub-basins, each with its own set of 184 landscape units and channels.…”

A comprehension of the erosion processes and sediment transport in the watershed is essential for the sustainable management of the water resources and soil fertility. In this study, the Water Assessment Tool (SWAT) model was applied to demonstrate its ability to modeling the suspended sediment transport in the Wadi K’sob basin (Northeast of Algeria). The data used to set up the SWAT model are the Digital Elevation Model (DEM), land use, soil types and weather data. The calibration was carried out using daily sediment yield data corresponding to two (2) periods( 10/10/2006 to 06/17/2007 and 10/29/2012 to 10/22/2013) and validation was performed using two (2) other periods (06/18/2007 to 11/19/2007 and 10/23/2013 to 09/13/2014) of daily sediment yield. R-SWAT code was used for calibration process and sensitivity analysis. The performance of the SWAT model was evaluated by the Nash–Sutcliffe criterion (NSE) and coefficient of determination (R2). The results obtained after calibration oscillating between good and satisfactory where (NSE = 0.67 and R2 = 0.73) in the first calibration period and (NSE = 0.65 b and R2 = 0.67) in the second period. For validation, the performance of the SWAT model was very good (NSE = 0.78 and R2 = 0.79) in the first period while in the second period the prediction of the model was satisfactory (NSE = 0.52 and R2 = 0.54). In addition, the validation process revealed that some parameters are stable and related on watershed characteristics while other unstable parameters depend on soil properties especially soil permeability and soil erodibility.
