Flood Damages Reduced New Feature - Agricultural Damages Reduced
The ability to compute agricultural flood damages reduced has been added to HEC-FIA 3.4.
This option is only available for simulations that use the Holdout - RAS HDF Inundation Configuration.
To calculate agricultural flood damages reduced, check the compute agriculture box in the Agriculture Tab in the Alternative Menu.
To improve compute time, ensure that the agriculture grid is clipped to the project extents.
When creating the Agriculture Grid within HEC-FIA, only import crops that are needed to calculate flood damages reduced. (For example importing land cover such as NLCD-Mixed Forest may severely slow down computation times).
Additional Tabs have been added to the Flood Damage Reduction Aggregated Report as seen below.
Agriculture Damage Tab
Selecting "Damage Category" in the View By dropdown menu will tabulate by Crop Type.
Acreage Reduced Tab has been added, and can also be sorted by geographic boundary or Crop Type (Damage Category).
A Total Damages Tab has also been added. This sums the Damages Reduced between the Structure and Agriculture Damages Tabs. Note that attempting to sort the Total Tab by Damage Category or Occupancy Type will result in a blank table.
Improvements to launching RAS Mapper from FIA
Opening RAS Mapper from the Simulation Menu will automatically add the result shapefiles as map layers for the HDF compute. Additional shapefiles for Agriculture Flood Damages reduced are also added. These include an overall results shapefile (AgFloodDamageReduced) and then four shapefiles representing the four scenarios:
Regulated (Reg_AgResults)
Regulated Without Levee (RegWOL_AgResults)
Unregulated (Unreg_AgResults)
Unregulated Without Levee (UnregWOL_AgResults).
Similar shapefiles are created for the structure flood damages reduced computation.
Sped up computation by only calculating Arrival and Duration when the Agriculture compute box is selected
Agriculture computations now compute the area of a grid cell based on the crop image. No longer assume a fixed acreage per cell
When launching RAS Mapper from the Simulation Menu for an Agriculture FDR compute, Agriculture FDR shapefiles are added automatically.
Beta Software User's Agreement Added
Retired Global Data. Access to the global data editor from the right click on project name menu has been removed. Urban and Agriculture Price Index can be edited through the Emergency Planning Zone Editor.
Bug addressed in the RAS HDF Inundation Configuration that resulted in incorrect depth sampling.
Added improved messaging when FIA cannot determine the projection of the included terrain. Warning message displayed and the terrain projection is set to X-Y coordinates.
Cleaned up and organized FIA install directory.
beta.6
FDR Agriculture Report now includes Acreage
FDR Report includes Total Tab that sums Structure and Agriculture Flood Damages Reduced
If a simulation has not been computed (Agriculture, Structure) the Aggregated Summary table will display with zero rows instead of zero values. This was found confusing to users who thought that FIA successfully computed but with zero damages.
When launching RAS Mapper from the Simulation Menu for a FDR compute, The default maps (Max Depth, Max WSE, and Velocity) are automatically added to the Menu Tree for the four RAS simulations. Previously each map had to be added manually each time RAS Mapper was opened
Configuration file updated - default memory allocated to FIA increased to 8GB.
File structure and organization of HEC-FIA installation directory improved
Build upgrades include upgrade to GeoTools 29 and Java 11.
Fixed bug that occurred when re-computing an existing Agriculture FDR simulation. The compute would fail due to a shapefile lock if previous compute was not successful.
HDF and terrain pathnames now relative
Bug addressed that caused Ag HDF compute to create folders and shapefiles in the C directory, regardless of where the project was located.
Addressed bug where the terrain was not correctly included when RAS Mapper was launched from FIA.
Fixed bug that prevented HEC-DssVue from launching from the Tools Menu.
