"I have over 15 years of experience in water resources engineering and I am the Engineering Team Lead at Stantec. I am responsible for quality assurance of engineering deliverables for our clients. I have extensive experience in working on FEMA floodplain mapping studies for nearly every FEMA Region in the US, including performing hydrologic and hydraulic engineering analyses, carrying out technical QA/QC, and training engineering and GIS staff. We have found that GeoHECRAS greatly improves our efficiency in completing HECRAS model studies. In my position as supervisor of our engineering team, I can see the challenges first hand that our staff has had in efficiently creating accurate flood studies using traditional tools with HEC-RAS. With our fixed budget on flood projects, we needed to improve our efficiency in completing these projects and GeoHECRAS has helped a lot in that regard. The post-processing that is built into GeoHECRAS has greatly improved the speed in which we can process the output from HEC-RAS. The semi-automated method in computing the FEMA floodway has really reduced the time required to complete a floodway analysis. We estimate that we save at least half the previous time required in performing post-processing, especially in doing floodway analyses. The graphical editing environment that GeoHECRAS provides makes it very easy and enjoyable to quickly define and make changes to a HEC-RAS model. For example, updating the cross section geometry is really nice because you can graphically edit the cross section in conjunction with the terrain data. Most engineers I know tend to not like change. However, if they do HEC-RAS modeling, I would strongly recommend that they look into using GeoHECRAS for speeding up their engineering workflow. I think that they will be really surprised at how much an improvement in efficiency and accuracy that this software provides."
