Soil erosion is a serious worldwide environmental problem that stems from a combination of several factors such as agricultural intensification, deforestation, increasing population, and rainstorms. This phenomenon produces a soil fertility decline, removes soil rich in nutrients and increases natural level of sedimentation in the rivers and reservoirs reducing their storage capacity as well as...

Le bassin versant à l’amont du barrage Hassan II, situé au cœur de la Haute Moulouya, est 3379 km² superficie et 512 km périmètre. présent travail a pour objectif d’estimer les pertes en sol niveau II dans Moulouya par l’utilisation des systèmes d’Information Géographique (SIG). La méthodologie adoptée basée sur une succession d’étapes permettant d’aboutir modèle final (carte d’érosion) utilisa...

The easy implementation of ecologically-sound remediation measures for the prompt stabilisation burned areas may be crucial in Mediterranean forest environments. Manual situ contour redirection felled logs could aid soil erosion control and facilitate self-regeneration. In this study, a plot-scale runoff/sediment yield survey was conducted Calabria, Italy, within pine that affected by an extrem...

cients. Normalizing to a unit plot of length 22.13 m, both the USLE and RUSLE use the equation Empirical soil erosion models continue to play an important role in soil conservation planning and environmental evaluations around L 5 (l/22.13) [2] the world. The effect of hillslope length on soil loss, often termed the where L is soil loss normalized to the 22.13-m-long slope length factor, is one...

The greatest obstacle to soil erosion modelling at larger spatial scales is the lack of data on soil characteristics. One key parameter for modelling soil erosion is the soil erodibility, expressed as the K-factor in the widely used soil erosion model, the Universal Soil Loss Equation (USLE) and its revised version (RUSLE). The K-factor, which expresses the susceptibility of a soil to erode, is...

Three different approaches using geographical information systems (GIs) and digital elevation models (DEMs) are described and evaluated for applying the Water Erosion Prediction Project (WEPP) model to assess water erosion in small watersheds. The first approach describes a typical application of the watershed version of WEPP using GIs only as an aidfor construction of required input files. The...
