Erosion Risk Assessment using an Empirical Model of Pacific South West Inter Agency Committee Method for Zargeh Watershed, Iran
MPSIAC Erosion Sediment Yield Iran
2015/1/6
Watershed degradation due to soil erosion and sedimentation is one of the major environmental problems in Iran. In addressing the issue, a study on the validity of an empirical model of Pacific South ...
Support Soil Conservation Practices by Identifying Critical Erosion Areas within an American Watershed Using the GIS-AGNPS Model
T value water quality modeling
2015/1/5
Eroded soil from overland is one of the major nonpoint pollution sources in many watersheds. The subsequent sediment not only reduces conveyance capacity of streams and usable storage volume of reserv...
Comparisons of local infiltration-excess, overland flow and associated erosion behaviour with river behaviour at the catchment scale
overland flow erosion catchment scale
2015/1/4
Modeling overland flow and erosional behaviour is a very important scientific task today to prevent environmental impacts from human activities as well as physical disasters such as floods and deserti...

FOREST MANAGEMENT PLANNING FOR SOIL CONSERVATION USING SATELLITE IMAGES, GIS MAPPING, AND SOIL EROSION MODELING
Soil conservation planning watersheds physical reconnaissance surveys
2009/10/12
Soil conservation planning in inaccessible mountainous watersheds is a very tedious and expensive job. Generally, in India most soil conservation programs are carried out with physical reconnaissance ...
THE EFFECT OF DIGITAL ELEVATION MODEL SCALE FACTOR ON SOIL EROSION STUDIES：CASE STUDY IN CAMERON HIGHLANDS, MALAYSIA
digital elevation model SOIL EROSION SCALE FACTOR
2009/10/12
The digital elevation model (DEM) is usually used to express a topographic surface in three dimensions and to imitate essential natural geography. The DEM is a model of the elevation surface, which is...
