Region 4 Upper Calcasieu 1D HEC-RAS Model - A14E Design Storms

This model represents the Upper Calcasieu watershed (HUC 08080203) within Region 4 of the Louisiana Watershed Initiative (LWI) Statewide Data and Modeling Program. It is a 1D HEC-RAS model that handles the hydraulic components of the simulations. This model was developed in conjunction with the HEC-HMS and 2D HEC-RAS models of the watershed. It uses input flows from the HEC-HMS model and provides flow results to the 2D HEC-RAS model in order to complete simulations. This particular version of the model contains plans for the Atlas 14 Everywhere (A14E) design storm methodology. It includes 7 return periods and 5 durations, resulting in 35 design storm events.

Note: Some common input files referenced by this dataset may be provided through the watershed's Supporting Files dataset that is the linked in the watershed's package.

The purpose of this model is to aid in coordination of funds, data, and resources which will help reduce flood risk through a watershed-based approach within the state of Louisiana.
