Abstract Elevated soil loss and runoff rates can reduce fertility; therefore, erosion control strategies must be implemented at the hillslope watershed scale when plantations are established is bare. In this research, we propose use of Vicia sativa Roth. to losses during first year peak after plantation in tilled vineyards. To test its efficiency, rainfall simulation experiments were carried out with field surveys The Casa Pago Gran, Eastern Iberian Peninsula. Our results demonstrate that properties (organic matter bulk density) (soil loss, sediment concentration) significantly different between plot (tilled) cover crops along August 2016, 2017 2018 measurement periods, but not January coinciding initial survey before vetch sown. Runoff initiation was delayed 3.7 times 3 years (from 190 till 709 s). discharge reduced by from 32.87 13.68%, concentration went down 18.54 3.81 gr l −1 3.36 0.29 Mg ha . An increase density registered did affect generation either losses, plant cover. We conclude it necessary include measures such as processes stages vineyard due quality improvements reduction water losses.

Soil erosion by water is the major form of land degradation in Chereti watershed, Northeastern Ethiopia. This problem exacerbated high rainfall after a long period dry seasons, undulating topography, intensive cultivation, and lack proper soil conservation measures. Hence, this study aimed to estimate 23 years (1995-2018) average rate watershed identify prioritize erosion-vulnerable subwatersheds for planning. The integration revised universal loss equation (RUSLE), geographic information system, remote sensing was applied long-term watershed.

Soil erosion (SE) and climate change are closely related to environmental challenges that influence human wellbeing. However, the potential impacts of both processes in semi-arid areas difficult be predicted because atmospheric variations non-sustainable land use management. Thus, models can employed estimate effects different climatic scenarios on interactions.

The Mediterranean part of Syria is affected by soil water erosion due to poor land management. Within this context, the main aim research was track and runoff after each rainy storm between September 2013 April 2014 (rainy season), on two slopes with different gradients (4.7%; 10.3%), under three cover types (SCTs): bare (BS), metal sieve (MC), strip cropping (SC), in Central Syria. Two statistical multivariate models, general linear model (GLM), random forest regression (RFR) were applied reveal importance SCTs. Our results that higher rate, as well runoff, recorded BS followed MC, SC. Accordingly, had a significant effect (p < 0.001) erosion, no difference detected MC Different combinations at least experiment. RFR performed better than GLM predictions. GLM’s median mean absolute error 21% worse RFR. Nonetheless, 25 repetitions 2-fold cross-validation ensured highest available prediction accuracy for In conclusion, we revealed rain intensity most important factors erosion.
