    Soil erosion projection based on the CMIP6 multi-model ensemble, case study of Wadi El-Ham watershed, northern Algeria

    This study uses the Revised Universal Soil Loss Equation (RUSLE) to estimate both historical (1990–2011) and future (2026–2050) soil-loss rates in the Wadi El-Ham watershed in northern Algeria under three CMIP6 climate scenarios (SSP1-2.6, SSP2-4.5, SSP5-8.5). Monthly precipitation (1975–2011) measured from eight meteorological stations and CMIP6 multi-model ensemble data from the IPCC AR6 Interactive Atlas were used to derive rainfall erosivity, with the delta method applied to correct bias for improve the quality of the results. Spatial inputs for soil erodibility, topography and land cover were derived from FAO soil maps, a 30 m DEM, and Landsat imagery ; respectively. The obtained results show a historical specific soil loss of 5.18 t ha⁻¹ yr⁻¹, predominantly concentrated on steep northern slopes, while more than half of the watershed experienced low erosion rates. The specific soil loss projected for the period 2026–2050 is expected to decrease by 24–29% compared to the historical period, with little change across scenarios (3.72–3.92 t ha/yr) and a slight contraction is expected in the most vulnerable areas, with continued vulnerability in the northern plateaus. The results of this study can guide erosion mitigation measures by identifying the most vulnerable areas. Furthermore, by highlight the key sources of uncertainty and challenges in modeling future erosion, they provide researchers with a basis for testing innovative approaches to address these limitations.

    Study of future projection of ectreme rainfall events using CMIP6 multi-mode, case of Soubella watershed , in Hodna region (Algeria)l

    Climate change is one of the main causes of global warming due to greenhouse gas (GHG) emissions that affect precipitation, runoff and groundwater recharge patterns, especially in arid and semi-arid regions. Therefore, estimating changes in extreme rainfall events is very important for assessment and management of flash flood risks. This study aims to evaluate potential changes and trends in heavy rainfall events in the Soubella watershed in Hodna region in central Algeria, where special emphasis will be placed on the annual maximum 1-day precipitation in the near and medium terms during the period 2025 to 2060 compared to the historical reference period of 1974-2013, which used to determine baseline conditions and to correct data bias from climate models. Future precipitation projections are obtained from the average CMIP6 multi-model ensemble under the SSP245 and SSP585 scenarios. The frequency and intensity of extreme precipitation events are expected to increase during the future period, especially under the extreme emission scenario SSP585, as it is expected to increase highlights to improve water resource management and flood risk mitigation strategies in the Soubella watershed, in addition to the importance of adaptation measures to address the impacts of climate change in semi-arid regions
