HEC-RAS 7.0.1
Bridge Plot - 1D Velocity Distribution
1D Velocity Distribution Plot for Unsteady Flow models is not displaying the correct number of slices for Bridge plots. One velocity for the channel and each overbank is shown. The plot was corrected for Cross Sections in version 7.0.1.
When a dataset contains a sluice gate in a Pipe Network and a gate on an SA/2D Connection or Lateral Structure a Fortran access violation can occur, preventing the model from running. Workaround: Change the ordering of the gate boundary conditions in the .u## file so that the Pipe Network gate entries come before the other gate entries as described here: Reorder Gates in Unsteady Flow File
IN PROGRESS
Unable to Import WPC - QPF data in GRIB2 format
The National Weather Service's Weather Prediction Center provides 2 national gridded precipitation products in GRIB2 format: Quantitative Precipitation Estimates (QPE) and Quantitative Precipitation Forecasts (QPF). Currently, RAS is unable to import the QPF dataset due to its compression type. Workaround: Use HEC-MetVue or HEC-Vortex to convert the QPF data to DSS before use in RAS.
FUTURE VERSION
Unable to Create Terrains from GeoTIFFs Exported from CAD Application
HEC-RAS geospatial libraries cannot determine the projection data stored in GeoTIFFs exported from a common CAD application. This results in a failure when importing the geotiff to a RAS terrain. Workaround: Reproject the terrain to a desired projection in a GIS application before importing. Alternatively, import the terrain in RAS before defining a projection in Mapper, then set the appropriate projection (spatialreference.org) following import.
FUTURE VERSION
GDAL Conflict when Opening RAS Mapper
"Error initializing the GDAL path variables. Please check HEC-RAS installation"error message is displayed when attempting to open RAS Mapper.
1RESOLVED - issue is fixed and will be available in the next release. 2IN PROGRESS - issue is currently being worked on. 3IMPROVED - the next version includes an incremental improvement but not a total fix. 4FUTURE VERSION - this requires a structural change or major development. The team will add it to a future version if funding permits.
