The erosion caused by the action of rain is one most frequent environmental problems, and it causes several damages, both material human. aim this research was to evaluate dynamics based on a quantitative analysis soil loss in Jaboatão river basin, located coast Center Forest Area Pernambuco. With focus applying Geoprocessing resources, used Universal Soil Loss Equation (USLE), which integrates...

In this research, the impact of a carbon sequestration project, in the Hossein Abad Plain in Southern Khorasan Province of Iran, on the status of water and wind erosion was evaluated. The study area has a harsh climatic condition with low annual precipitation and is prone to well-known 120-day winds in summer. Since 2005, various soil conservation treatments (plantations, over-sowing, plantatio...

This study aimed to assess the erosion hazard level in Wairutung Watershed. The land unit this was generated from overlaying use maps, slope and soil types maps. class of vulnerability determined based on sum parameters' rating results using a computer-based Geographic Information System (GIS) with ArcGIS program, which integrated Universal Soil Loss Equation (USLE) model. indicated division 4 ...
