Research Project: WEPP Web-based Field Watershed Interface Development

Location: National Soil Erosion Research

Project Number: 5020-12130-003-14-I
Project Type: Interagency Reimbursable Agreement

Start Date: Sep 15, 2016
End Date: Sep 30, 2019

Objective:
1) Provide the Cooperator the science and software, via the Cooperator web-based version of WEPP, to predict soil loss, sedimentation, gully erosion prediction, and quantify gully erosion on small watersheds or designated fields using digital elevation models and LiDAR technologies. 2) Provide additional specialized reports from the WEPP input and output files. 3) Develop a management file transfer system between the web-based versions of WEPP and WEPS.

Approach:
This project will build upon ongoing efforts at the ARS to create web-based interfaces for use by Cooperator and their service providers to estimate runoff, soil loss, and sediment delivery from fields and small field-sized watersheds using the USDA Water Erosion Prediction Project (WEPP) model. Specifically in this portion of the work, ARS will: 1) Explore additional automated methods to analyze landscape properties to facilitate the auto creation of flow paths, sheet erosion, rill erosion, gully erosion, sedimentation and program the necessary software to work within the Cooperator WEPP model. 2) Coordinate with ARS WEPS developers to develop a management file transfer between WEPP web-based version and WEPS web-based version (this is assuming management files are saved on a local computer). 3) Provide conservation practice Implementation Requirement reports based on the input into WEPP and the results produced by WEPP. NRCS will address the day-to-day issues and assist in presenting a suitable interface and inputs to accomplish small watershed/field erosion prediction. They will also provide the format and identify the needed content for the conservation practice “Implementation Requirements”.
