Research Project: Provide BSTEM Modeling Support to USACE, Sacramento District, for Evaluation of Bank Erosion on the American River

Location: Watershed Physical Processes Research

Project Number: 6060-13000-026-40-I
Project Type: Interagency Reimbursable Agreement

Start Date: Aug 1, 2018
End Date: Sep 30, 2019

Objective:
To provide expertise and support on the development of BSTEM bank erosion simulations for the American River by the U.S. Army Corps of Engineers, Sacramento District (USACE). Specific objectives are: 1. Provide quality control for the BSTEM model simulations performed by USACE. 2. Provide technical expertise when USACE runs into difficulties with the BSTEM model simulations. 3. Refine the BSTEM Dynamic model to allow Monte Carlo simulations for select inputs. Addition funds to pay for: 4. Collect data on soil erosion resistance at 20 locations on the American and Sacramento Rivers. 5. Quantify variability in soil erosion resistance parameters.

Approach:
Members of the USDA, ARS BSTEM development team (Team), will conduct BSTEM Dynamic training to USACE, SD, and provide technical expertise, review, and quality control on BSTEM bank erosion simulations for the American River conducted by USACE. ARS will review documentation of the parent USACE project. The TEAM will develop a Monte Carlo simulation module for BSTEM Dynamic.The TEAM will collect new data and evaluate historic data on soil erosion resistance to quantify its variability for use in the Monte Carlo simulations.
