The aim of the present work was to evaluate the possibilities of using sub-basin data for calibration of the Soil and Water Assessment Tool (SWAT) model in a small ungauged basin (46 ha) and its response. This small basin was located in the viticultural Anoia-Penedès region (north-east Spain), which suffers severe soil erosion. The data sources were: daily weather data from an observatory locat...

This is a review paper on the effects of aluminum sulfate (alum) on ammonia volatilization and P runoff from poultry litter. Initially, laboratory studies were conducted that showed P solubility could be reduced in poultry litter with Al, Ca, and Fe amendments, indicating that these amendments may reduce P runoff. These results were confirmed in small plot studies in which alum applications to ...

Rainfall simulations allow for controlled comparisons of runoff and erosion among ecosystems and land cover conditions. Runoff and erosion can increase greatly following fire, yet there are few rainfall simulation studies for post-fire plots, particularly after severe fire in semiarid forest. We conducted rainfall simulations shortly after a severe fire (Cerro Grande) in ponderosa pine forest n...

It is an important branch of erosion research to control soil on eroded gullies and slopes by using vegetation filter strip. Several simulated rainfall experiments were carried out in tanks filled with loess sandy loam taken from a typical gully area less coverage Yanghe hilly basin Xuanhua District, Zhangjiakou City, Hebei Province. The water conservation effects two different setting modes co...

The present study was conducted to test the efficiency and applicability of EROSION-3D (Jürgen Schmidt, Berlin, Germany) model in lower Shivaliks Northwest India. Two similar micro-watersheds terms soil characteristics land use were selected for calibration validation model. calibrated using data from seven rainstorms micro-watershed A validated 11 B. After calibration, overall statistical para...

Soil Conservation Service (SCS) and overland flow models have been used for runoff modeling over major land mass of India. Remote sensing derived daily rainfall data (Climate Prediction Centre), high temporal NDVI data (SPOT VGT), DEM (GTOPO30) and soil texture maps were used as input for the runoff modeling. SCS model setup was done in GIS (Arc GIS) environment. In general the reported and mod...
