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...

Agricultural residues have been identified as a significant potential resource for bioenergy production, but serious questions remain about the sustainability of harvesting residues. Agricultural residues play an important role in limiting soil erosion from wind and water and in maintaining soil organic carbon. Because of this, multiple factors must be considered when assessing sustainable resi...

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 work describes a genetic programming (GP) approach that creates vegetation indices (VI’s) to automatically detect the sum of healthy, dry, and dead vegetation. Nowadays, it is acknowledged that VI’s are the most popular method for extracting vegetation information from satellite imagery. In particular, erosion models like the “Revised Universal Soil Loss Equation” (RUSLE) can use VI’s as i...

The classification of soils originated from three main sources: from early empirical soil surveys, from folk soil classifications and from scientific theory of pedology. The first soil classifications reflected their origin in different extent, and still remain certain features of their initial sources. The actual situation in soil classification is discouraging, mainly due to the diversity of ...

Estimation of soil loss from single storm events is essential for basin planning and nonpoint source pollution control. Rainfall-runoff erosivity factors for single storm events in northern Iraq were derived from the basic theory of soil detachment and transport. The factors derived are a single parameter which includes runoff depth only and a factor which combines runoff depth and peak rate. T...

The National Pollutant Discharge Elimination System (NPDES) Phase II requires construction activities to have erosion and sediment control best management practices (BMPs) designed and installed for site storm water management. Although BMPs are specified on storm water pollution prevention plans (SWPPPs) as part of the construction general permit (GP), there is little evidence in the research ...

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...

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 ...

The black soil region of Northeast China has suffered from severe soil erosion by water. Hillslope and gully erosion are the main erosion types. The objective of this research was to integrate the assessment of hillslope and gully erosion and explore spatial coupling relations between them in the Mushi River sub-catchment using geographical conditions monitoring (GCM) including remote sensing (...
