Channel Process

Bank Stability and Toe Erosion Model (BSTEM)

Science and Analysis has partnered with members of NCSU BAE to develop a process-based framework for predicting bank erosion and sediment transport associated with stream restoration practices.

The goal is to develop a regionalized tool for accurately predicting bank erosion and sediment transport related to pre-and-post stream restoration conditions. 

 

 

 

 

 

 

 

 

 

 

 

The Mini JET (Jet Erosion Test) above is used to measure in-situ critical shear stress and erodibility coefficient; both of which are input parameters to the Bank Stability and Toe Erosion Model (BSTEM). 

Channel Change

DMS, NCSU and the NC Sea Grant are partnering to evaluate the physical adjustment in stream geometry occurring after the end of the five-year monitoring period. 

This data will provide the mitigation community with a better understanding of how channels adjust in the years following restoration. The knowledge acquired from this work will facilitate improved design and monitoring efforts.
