v3.3 Release Notes
Final Release:
Initial Beta Release:
Flood Damages Reduced New Features
New Holdout - RAS HDF Inundation Configuration
A new inundation configuration was created to provide more flexibility in the computation of flood damages reduced. This new compute is intended for use in watersheds with large leveed areas, or leveed areas with complex hydraulics where the current without levee damage estimations in HEC-FIA are not appropriate. Instead of accepting only 2 hydraulic inputs, regulated and unregulated, this configuration accepts 2 additional hydraulic inputs for the regulated without levee and the unregulated without conditions. This allows a user to compute the without levee hydraulics in HEC-RAS, instead of relying on the without levee estimation in HEC-FIA.
In order to reduce compute time and storage needs, this inundation configuration accepts native HDF5 HEC-RAS outputs for the four scenarios. Hovering over the input titles (Regulated HDF, Regulated Without Levee HDF, etc) provides the user with additional information to help select the associated .hdf file.

RAS Mapper Beta Feature
A new beta feature is available for testing that allows a user to launch an abbreviated version of HEC-RAS Mapper from within HEC-FIA. The feature will allow users to more easily perform quality control on their HEC-FIA results by comparing against HEC-RAS inundations. HEC-FIA will gather all the inputs from the inundation configuration event, and the HEC-FIA results to display them in HEC-RAS Mapper.
This feature is included by default in v3.3. This feature is accessed through right-clicking the computed simulation of a Holdout - RAS HDF Inundation Configuration and selecting the Beta labeled menu item. If desired to remove the new feature, edit the HEC-FIA.config file, and set the 'vmparam -Dras.launch.mapper.beta=false'.
For HEC-FIA results to display in the RAS Mapper launched from within HEC-FIA, the HEC-RAS inundations must be from HEC-RAS 6.1 or newer.
