The Soil and Water Assessment Tool (SWAT) is used worldwide for water quality assessment and planning. This paper aimed to assess and adapt SWAT hillslope sediment yield model (Modified Universal Soil Loss Equation, MUSLE) for applications in large basins, i.e. when spatial data is coarse and model units are large; and to develop a robust sediment calibration method for large regions. The Upper...

Abstract This article presents the identification of soil use potential for different agropastoral and forest scenarios, using an indicator erosion susceptibility from spatialized Universal Soil Loss Equation (USLE). All USLE factors were ArcGis 10.5 software, case study Cachoeira Cinco Veados Watershed-RS. To determine R factor, we used Cassol et al. 2007 equation a 33-year series rain data si...

Soil erosion is a severe and continuous environmental problem caused mainly by natural factors, which can be enhanced anthropogenic activities. The morphological relief with relatively steep slopes, the dense drainage network, Mediterranean climate are some of factors that render Paleochora region (South Chania, Crete, Greece) particularly prone to soil in cases intense rainfall events. In this...

This study, using different direct and indirect methodologies, evaluated the sedimentation rate in an artificial reservoir central Italy. is regionally representative was built 1960s for hydroelectric purposes; it has experienced a strong decrease trap efficiency loss of over 70% stored water volume. Direct measurements lake bottom bathymetry, carried out 2006 2015, 3D reconstructions performed...

Introduction The Wind Erosion Prediction System (WEPS) is a process-based, daily time-step model that simulates weather, field conditions, and erosion. WEPS development is in response to customer requests for improved wind erosion technology. It is intended to replace the predominately empirical Wind Erosion Equation (WEQ) (Woodruff and Siddoway, 1965) as a prediction tool for those who plan so...

Abstract Water erosion is among the largest and most crucial problems with soil loss that through land degradation in semi-arid regions North African areas are especially vulnerable to it. In addition, EL-Mador Valley Basin exposed due climate topographic properties as well a human activity. this scope, aim of study perform an evaluation hazards El-Mador by employing equation RUSLE data RS with...
