Soil erosion is one of the problems threatening Algerian environment. In agriculture, soil leads to thinning topsoil under effect natural erosive forces water, or agricultural activities. The present study aims estimate average loss rate and identify vulnerable zones. Through integration RUSLE model at Saf watershed, various parameters are utilized such as rainfall erosivity factor (R), erodibi...

The salinization of surface water in a coastal context leads to qualitative degradation this resource by various sources anthropogenic and natural pollution. In context, we present the results comparative study using "DKPR" "RUSLE" models evaluate degree vulnerability against pollution, especially sub-watershed Joumouaa dam, hydraulic infrastructure providing drinking for Targuist city. model a...

Some methodologies were compared in providing erosion maps of surface, rill and gully and erosion features, in research which took place in the Varamin sub-basin, north-east Tehran, Iran. A photomorphic unit map was produced from processed satellite images, and four other maps were prepared by the integration of different data layers, including slope, plant cover, geology, land use, rocks erodi...

Land application of biosolids is a beneficial-use practice whose ecological effects depend in part on hydrological effects. Biosolids were surface-applied to square 0.5-m2 plots at four rates (0, 7, 34, and 90 dry Mg ha(-1)) on each of three soil-cover combinations in Chihuahuan Desert grassland and shrubland. Infiltration and erosion were measured during two seasons for three biosolids post-ap...
