LWI Region 5 Mermentau Headwaters - Bayou des Cannes near Redland HEC-RAS Model: Historic Event scaled to 500-Year Design Storm

This simulation represents the 500-year design storm event for the KCDA Bayou des Cannes near Redland (MH_BDC3_46_UG). The event is based on the August 2016 historical tropical storm scaled to the 500-year 24-hour design storm precipitation volume. The storm critical duration was determined by modeling the gridded precipitation over the KCDA area and identifying the peak flow leaving the KCDA area for a variety of storm lengths. To match the design storm volume, the August 2016 historical storm was configured with a 1.55 scale factor for KCDA MH_BDC3_46_UG.
