LWI R7 Lake Maurepas St. John the Baptist SWMP PoC

The Lake Maurepas St. John the Baptist SWMP PoC HEC-RAS model is a 2D hydraulic model within the Lake Maurepas Watershed. The model is a 2D unstructured computational mesh developed in HEC-RAS 6.4.1 and forced with inflow hydrographs developed from the HEC-HMS software. This model provides results for the AEPs based on the Atlas14 Everywhere approach.

The purpose of this PoC model is to evaluate potential mitigation solutions to address identified flood risk within Region 7, and to demonstrate a potential use case of the LWI models to be used for assessment of flood risk reduction solutions. This model specifically focuses on various mitigation projects within St. John the Baptist Parish for their Stormwater Master Plan update..
