EROSION PREDICTION INTRODUCTION This section contains information on predicting soil erosion rates in New York State. The Revised Universal Soil-Loss Equation (RUSLE) and the Wind Erosion Equation (WEQ) are used to compute erosion rates. The erosion prediction models are empirical equations derived and tested by Size: KB.

Hydrologic modeling of range-land erosion processes has made significant advances in the past five years with the development of the Water Erosion Prediction Project (WEPP) model. Research to refine hydrological models will continue because of the extensive-ness and variability of rangelands on a .

the prediction of soil loss and sediment delivery. The importance of estimating erosion and sediment delivery has long been recognized to minimize pollution by sediments and the chemicals carried by soil particles. The visual effects of erosion include rills and gullies along with sediment blockages found in culverts or drainage Size: 1MB. When the Water Erosion Prediction Project (WEPP) computer model was used to simulate the effect of terraces, grassed waterways, and buffer strips, the sediment lost with the combination of chisel plowing, terraces, and grassed waterways was still two and a half times greater than with no-till by itself.

CPIDS. () Crop Parameter Knowledge Based System. CPIDS was developed to assist crop database builders and users of RUSLE and WEPP in interpretation of plant characteristics and selection of plant parameters. RUSLE, WEPP and other erosion prediction and natural resource models require detailed input parameters including those describing.
Water Erosion Prediction Project (WEPP) in August to produce new‐generation water erosion prediction technology for use by federal action agencies involved in soil and water conservation and environmental planning and assessment.
Water erosion prediction project book that time, the soil erosion prediction tool in widespread use was the Universal. The erosion rates and sediment delivery are predicted by the Water Erosion Prediction Project (WEPP) model, using input values for forest conditions developed by scientists at the Rocky Mountain Research Station.
The WEPP soil erosion model is being developed by an interagency group of scientists, including the following personnel at the Moscow Forestry Sciences Lab: William J.
Elliot (Project. The Water Erosion and Prediction Project (WEPP) model was developed as a cooperative effort of four organisations with the leading role for the U.S. Department of Agriculture. The main aim was to employ the current knowledge to develop a model as an alternative to USLE. Water Erosion Severe rill and sheet erosion on highly erodible soils in Cass County, Iowa.

The Water Erosion Prediction Project (WEPP) Model is a physically based erosion simulation model built on the fundamentals of hydrology, plant science, hydraulics, and erosion model was developed by an interagency team of scientists to replace the Universal Soil Loss Equation (USLE) and has been widely used in the United States and the world.
The objective of the Water Erosion Prediction Project is to develop new generation prediction technology for use by the USDA-Natural Resources Conservation Service, USDA-Forest Service, USDI-Bureau of Land Management, and others involved in soil and water conservation and.
Introduction. The WEPP erosion model, first released inis a process-based, distributed parameter, continuous simulation, erosion prediction model that computes soil loss along a slope and sediment yield at the end of the hillslope for small watersheds.
The Water Erosion Prediction Project (WEPP) is a physically based model which has frequently been applied in the world for soil erosion and runoff prediction on channel, hillslope, and watershed.
Nearing, MA, and Nicks, AD,Evaluation of the Water Erosion Prediction Project (WEPP) model for hillslopes: in Modelling Soil Erosion by Water (J Boardman and DT Favis-Mortlock, eds.), Springer-Verlag NATO-ASI Series 1–55, Berlin: Google ScholarCited by: There are dozens of erosion prediction models focus on long-term (natural or geological) erosion, as a component of landscape r, many erosion models were developed to quantify the effects of accelerated soil erosion i.e.
soil erosion as influenced by human activity. Most soil erosion models consider only soil erosion by water, however a few aim to predict wind erosion. D.K. McCool, J.D. Williams, in Encyclopedia of Ecology, Soil erosion by water is the wearing away of the earth’s surface by the force of water and gravity, and consists of soil particle dislodgement, entrainment, transport, and deposition.
This sequence of events occurs over a wide range of temporal and spatial scales, from raindrop splash moving particles millimeters in milliseconds. Water erosion prediction project (WEPP) forest applications.
Ogden, UT: U.S. Dept. of Agriculture, Forest Service, Intermountain Research Station,  (OCoLC) The Water Erosion Prediction Project (WEPP) (Laflen et al., ; Flanagan and Nearing, ) model is a continuous simulation, process-based model that allows simulation of small watersheds and hillslope profiles within those watersheds for assessing various soil and water conservation management options for agricultural, rangeland, and forest.
The Daily Erosion Project (DEP) estimates soil erosion and water runoff occurring on hill slopes in Iowa and surrounding states. Estimates are based on hill slope conditions (e.g. topography, crop, precipitation) identified via remote sensing tools like satellites.
WEPP is a project to develop a fundamentally based soil erosion prediction technology. It was initiated inincluded a strong research program to develop specific technology needed for WEPP, and was organized around a team of research scientists and user agency personnel.

The Water Erosion Prediction Project (WEPP) watershed model is a distributed continuous simulation model developed to compute the spatial and temporal distribution of erosion and deposition within small agricultural watersheds.
The model is made up of three major components; hillslope, channel, and Cited by: 2. Water erosion is the wearing away of the soil surface by water from rain, runoff, snowmelt, and irrigation.
Rainwater in the form of runoff is the main driver of water erosion. It refers to the movement of soil organic and inorganic particles along the soil surface with flowing water and deposition of the eroded materials at lower landscape.

However, as the catchment size increases, the complexity of developing and organizing all WEPPCited by: This chapter describes models of soil erosion, with particular focus on soil erosion by water.
Models are used in conservation work for three primary purposes: (a) to help a land owner or manager choose suitable conservation, (b) to make broad‐scale erosion surveys to understand the scope of the problem over a region, and (c) to track changes in erosion over by: Water Erosion Prediction Project (WEPP): WEPP is a process-based, distributed parameter, continuous simulation, erosion prediction model.
It can simulate hill slope erosion processes, as well as simulation of the hydrologic and erosion processes on small watersheds. Pesticide Toxicity Indicators.
