LWI R7 Bayou Sara-Thompson (Bayou Baton Rouge) HEC-RAS Model

The Bayou Sara-Thompson (Bayou Baton Rouge) HEC-RAS model is a 1D/2D hydraulic model of the Bayou Baton Rouge watershed within Bayou Sara-Thompson. The model is a combination of 1D cross-sections and 2D unstructured computational mesh. The model was developed in HEC-RAS 6.4.1. The model was forced with inflow hydrographs developed from the HEC-HMS software.

The Bayou Sara-Thomson (Bayou Baton Rouge) numerical model (BSTBBRNM) was developed to support the Louisiana Watershed Initiative (LWI) to develop hydrologic and hydraulic models covering the Bayou Sara-Thompson watershed. The model provides a framework to develop: flood mitigation studies; no adverse impact assessment; consequences and risk assessment; and support evaluation of proposed projects, watershed management strategies and policy development.
