You need a hydraulic engineer to obtain the HEC-RAS model of the site...they would have to make a request to FEMA for the model (there is a fee for FEMA to search their library and provide this)...half the time, despite being an AE zone they can't find the model, in which case I will usually look to ...

Check the local jurisdiction's Flood Damage Prevention Ordinance (FDPO). If the jurisdiction is a participant in the National Flood Insurance Program (NFIP), then they are required to adopt the minimum model FDPO, although they may adopt higher standards.

You have pointed out something very important – that is not only limited to the model simulation of navigational channel sedimentation – but also in other areas of water modeling. As far as I know, the Verification & Validation ( V&V , ...

Hey Bill, Just adding to the discussion, my background is primarily 1D/2D hydraulic flood modeling so terms might be used a little differently. We used a similar definitions for a document we worked on in the EWRI Computation Hydraulics Technical Committee, document is still in the works but we had ...
