Accurate estimation of soil erosion due to water is very important in several environmental contexts, such as the assessment of potential soil loss from cultivated lands and the evaluation of the loss of water storage capacity in reservoirs due to sediment deposition. Several studies have been carried out to build models suitable to quantify the results of erosion processes. These models, calib...

For two watersheds in the northern Midwest United States, we show that landscape depressions have a significant impact on watershed hydrology and sediment yields and that the Soil and Water Assessment Tool (SWAT) has appropriate features to simulate these depressions. In our SWAT models of the Willow River in Wisconsin and the Sunrise River in Minnesota, we used Pond and Wetland features to cap...

The multitemporal behavior of soil loss by surface water erosion in the hydrographic basin of the river Mourão in the center-western region of the Paraná state, Brazil, is analyzed. Forecast was based on the application of the Universal Soil Loss Equation (USLE) with the data integration and estimates within an Geography Information System (GIS) environment. Results had shown high mean annual r...

Performing a comprehensive sensitivity/uncertainty analysis is a valuable step in understanding and using a predictive hydrologic/water quality (H/WQ) model. This article applies one-factor-at-a-time (OAT) sensitivity analysis (SA) and first-order error analysis (FOEA)/Monte Carlo simulation with Latin hypercube sampling (LHS) uncertainty analysis techniques for evaluation of a complex, process...

The objective of this study was to evaluate and compare the erosion rates generated by two types hand tools for small-scale tillage on a hillslope, using experimental tests Universal Soil Loss Equation (USLE). evaluated were conventional hoe redesigned furrowing hoe. work conducted in 145 m2 plot with an average slope 45% Colombia. Three treatments evaluated: a) Zero no herbicide (control); b) ...

Vulnerability of soil separates to detachment by water is described as soil erodibility by Universal Soil Loss Equation which can be affected by land use change. In this study it was attempted to quantify the changes of Universal Soil Loss Equation K-factor and its soil driving factors in three land uses including rangeland, rainfed farming, and orchards in Babolrood watershed, northern Iran. S...

A model was developed for estimating average annual soil loss by water on hillslope for cropland, which is called Chines Soil Loss Equation (CSLE). Six factors causing soil loss were evaluated based on soil loss data collected from experiment stations covering most regions of China and modified to the scale of Chinese unit plot defined. The model uses an empirical multiplicative equation, A=RKL...

Pakerisan watershed is one of the that has not followed rules soil and water conservation. This can destroy aggregates cause high erosion. study aims to predict level erosion plan Erosion prediction uses USLE (Universal Soil Loss Equation). The showed classified from slight severe. rate very light covering an area 6,426.26 ha (71.28%) with natural forests, dryland agriculture, paddy fields. mod...

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 ...
