HEC-RAS 7.0.2

 Issues 

Description

Status

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.

FUTURE VERSION

SI Conversion Issue for DL Breach Variables (E and Tc)

There is a conversion error in the SI mode of DL Breach.  The interface does not send the correct Erodibility or Critical Shear correctly to the DLBreach engine.  SI models that use these variables will erode too fast (by a lot).  Workaround: If you enter erodibility and critical shear in US Customary units () in an SI model, it should compute correctly. 

RESOLVED


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.
