SCIENCE AND TECHNOLOGY TRANSFER FOR THE WIND EROSION PREDICTION SYSTEM (WEPS)

Wind erosion prediction

United States Department of Agriculture (USDA) Research, Education & Economics Information System (REEIS)

Titre : SCIENCE AND TECHNOLOGY TRANSFER FOR THE WIND EROSION PREDICTION SYSTEM (WEPS)

Identification : 3012-61660-007-12S

Pays : Etats Unis

Durée : May 1, 2015 à Jan 31, 2016

Domaine : Rangelands and grasslands, general ; Soil ; Climate

Partenaire : COLORADO STATE UNIVERSITY FORT COLLINS

Objectif
1) Perform necessary sampling, data analysis and reporting of results for defining organic soil attributes from NRCS soil survey to be used as input into WEPS. 2) Review and update WEPS Science model technical documentation, update the WEPS User Manual and training exercises to align with current WEPS interface, databases, science model and reporting tools. 3) Develop, test and program as necessary to include sub-region functionality in WEPS science model, interface, and reporting for NRCS use in conservation planning.

Descriptif
1) Complete the temporal change study based on completed organic and muck soil sampling and sample results to analyze and report the results. Continue a rainfall simulation study on organic soils to document soil crusting and erodibility properties, review hydrology literature for simulating organic soils in WEPS. 2) Update the technical research documentation and training materials for the current NRCS release of WEPS. Update the WEPS user manual and training exercises to accurately reflect the current science and management of wind erosion. 3) Evaluate program, and test sub-region approach for modeling multiple soils, barriers, crop management systems for improved simulation of within-field variability.
