LWI Region 5 Mermentau Headwaters - Atlas 14 Everywhere HEC-RAS Model: 200-Year Design Storm
This simulation represents the 200-year design storm event for the Mermentau Headwaters Atlas 14 Everywhere (MH_A14E) model. 200-year 24-hour NOAA Atlas 14 rainfall depths and an assumed balanced hyetograph (nested) applied over the entire model domain to simulate pluvial flooding.
