LWI Region 5 Mermentau Headwaters - Bayou des Cannes at Eunice HEC-HMS Model: Historic Event scaled to 25-Year Design Storm

This watershed simulation models a 25-year design storm for the KCDA Bayou des Cannes at Eunice (MH_BDC3_35_G). The August 2016 historical tropical storm scaled by a factor of 0.85 to represent the 25-year 48-hour design storm precipitation volume was used as the meteorological input to the HMS model. Results of this simulation are applied as inputs to the LWI Region 5 Mermentau Headwaters HEC-RAS Model 25-year design storm simulation over MH_BDC3_35_G. Basin: B_CalibratedBase - Tc, None. Meteorology: DC35G_25YR_AUG2016_SF0.85V2, None. None. HMS 4.12
