Webthat the ‘effective’ hydraulic model is unavailable, an alternative hydraulic model must be calibrated to reproduce the FIS profiles within 0.5 feet. Hydraulic models used in the analysis must be on FEMA’s accepted models list. A “no-rise” analysis must show no impact on the 100-year flood elevations at the new cross-sections and WebFEMA now encourages the use of the software package known as HEC-RAS for new flood studies. The conversion of effective studies from HEC-2 into HEC-RAS is also encouraged. However, it should be noted that FEMA does accept models developed using other software packages.
