Citarum is the largest watershed in West Java, which home to 25 million people. In such a large and populated watershed, land conversion an inevitability. This condition directly encouraged increase erosion rates, impacted increasing sedimentation rates rivers, lakes, dams. research aimed assess spatial characteristics of soil Watershed using USLE method. The results showed that 45% was class I hazard with rate ≤15 tons/ha/year, 18% II (15–60 tons/ha/year), 26% III (60–180 5% IV (180–480 remaining 6% V (>480 tons/ha/year). Total annual reaches 80.1 tons, 52% contributed by Middle (42.0 tons/year), Upper (21.2 22% Lower (17.0 tons/year). proposed control measures for hotspot locations throughout include structural nonstructural approaches, are also proposed.

Soil erosion and sediment transport are significant concerns in the Yaqui River sub-basin northwest Mexico, driven by land use changes environmental degradation. This study aims to evaluate processes between 2000 2020 using a combination of satellite imagery numerical simulations with Iber software (Version 2.5.2). The primary objective is assess impacts changes, particularly conversion forest grassland, on rates transport. Satellite images from were analyzed detect cover while Iber’s module was used simulate patterns based Meyer–Peter Müller equation for bedload Hydrological topographical data incorporated provide accurate flow velocity, depth, potential. results reveal 35.3% reduction cover, leading increased steep areas. Simulation predictions highlighted areas high future potential, which at risk further soil loss if current trends continue. Flow velocity increased, contributing riverbank destabilization higher yield, posing infrastructure such as Álvaro Obregón Dam. underscores need targeted control measures sustainable management practices mitigate risks protect vital Basin.

Land degradation and sedimentation are global issues stemming from inappropriate land management practices within watersheds, primarily due to soil erosion. The primary aim of this investigation was estimate sediment yield, pinpoint erosion-prone areas, determine effective strategies for reducing erosion yield the Mormora watershed utilizing SWAT model. performance model assessed through calibration validation procedures employing Sequential Uncertainty Fitting 2 (SUFI-2) algorithm Calibration Procedures (SWAT-CUP). conducted period 1993 2006, while carried out 2007 2013, focusing on streamflow yields at gauging station. Various metrics including R , NSE, RSR, PBIAS were used assess performance. All indicated high accuracy. average annual outlet 1.19 million t/year with a spatial 8.54 t/ha/year. About 47.33% critical areas demanding implementation conservation strategy. effectiveness five scenarios compared existing baseline conditions their in reduction. results indicate decreased by 28.3% 55.9% applying filter strips, 61.7% 68.4% grassed waterways, 71.38% terracing, 62.64% contouring, 46.3% stone/soil bunds. Ultimately, terracing emerged as most strategy mitigating study area. Consequently, research outcomes developed methodology serve valuable resource decision-makers, experts, researchers involved sustainable management.

Soil erosion is one of the most significant problems in global environmental development. Assigning, analyzing, and quantifying main physical characteristics drainage basins are powerful keys identifying regions where there a higher risk soil prompt mitigation actions needed. Drainage their systems ideally defined using analysis morphometric parameters quantitative description. The present study aims to analyze prioritize that prone erosion. Topographic sheets remotely sensed digital elevation model (DEM) datasets have been prepared analyzed geospatial techniques delineate different sizes extract ordered systems. Based on parameters, Rabigh area was divided into 12 basins, which significantly contribute determining priority levels. selected applied effective rank after considering crucial characteristics, such as linear, relief, areal aspects. For each single basin, compound factor assigned from several area. results confirm Basins 1, 4, 11, require high level over an 2107 km2; however, 3, 8, 9, 10 little degradation low priority. Therefore, factor, terracing, filter strips, contouring, other useful structural non-structural methods should be applied.
