LWI Region 5 Mermentau Headwaters - Atlas 14 Everywhere HEC-RAS Model: 10-Year Design Storm

This simulation represents the 10-year design storm event for the Mermentau Headwaters Atlas 14 Everywhere (MH_A14E) model. 10-year 24-hour NOAA Atlas 14 rainfall depths and an assumed balanced hyetograph (nested) applied over the entire model domain to simulate pluvial flooding.
