Research Project: Provide Soil Erosion-resistance Data to USACE, Sacramento District, for Evaluation of Bank Erosion on the American and Sacramento Rivers

Location: Watershed Physical Processes Research

Project Number: 6060-13000-026-42-I
Project Type: Interagency Reimbursable Agreement

Start Date: Mar 1, 2019
End Date: Sep 30, 2020

Objective:
To provide expertise and support on soil erosion-resistance data for the development of Bank Stability and Toe Erosion Model (BSTEM) bank erosion simulations for the Sacramento and American Rivers by the U.S. Army Corps of Engineers, Sacramento District (USACE). Specific objectives are: 1. Collect data on soil erosion resistance at select locations on the American and Sacramento Rivers using a variety of testing methodologies. 2. Compare the different techniques (Jet Erosion Test (JET), Borehole Erosion Tests (BETs), Pocket Erodometer Tests (PETs), Erosion Function Apparatus (EFA)) used to quantify soil erosion resistance parameters.

Approach:
Members of the USDA, ARS BSTEM development team (TEAM), will provide technical expertise, review, and quality control on the collection of soil erosion-resistance data for the development of Bank Stability and Toe Erosion Model (BSTEM) bank erosion simulations for the American and Sacramento Rivers conducted by U.S. Army Corps of Engineers (USACE). In collaboration with Texas A&M Transportation Institute, the TEAM will conduct Borehole Erosion Tests (BETs), Pocket Erodometer Tests (PETs), and Erosion Function Apparatus (EFA) tests to measure soil erosion-resistance data. These data will be compared to previously measured Jet Erosion Test data collected by ARS and USACE.
