LWI Region 5 Mermentau Headwaters - Bayou Jonas at Interstate 10 near Egan HEC-RAS Model: Historic Event scaled to 10-Year Design Storm
This simulation represents the 10-year design storm event for the KCDA Bayou Jonas at Interstate 10 near Egan (MH_MdlC_07_UG). The event is based on the August 2016 historical tropical storm scaled to the 10-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 0.50 scale factor for KCDA MH_MdlC_07_UG.
