HEC-RAS 6.5

1D Sediment Results Not Reporting Tabular Data

When you run a 1D sediment file, the "Table" is blank (reports "no data to tabulate").  
Workaround: If you right click on the plot, you can select an option called "Tabulate This Chart"
This will launch another window with the tabular data for the variables plotted..

IN PROGRESS

The "Clastic" Non-Newtonian methods (Coulomb and Voellmy) are not working 

We have verified that these clastic methods are not producing significantly different results from the clear-water, Newtonian simulations.  Workaround: Use one of the other methods.  Bingham has been effective in a wide range of situations.

IN PROGRESS

Copy (Ctrl+C) in Attributes Table

When doing a copy in the attributes table in RAS Mapper, additional empty lines may appear when pasting.  Workaround: Paste the data first into another program such as Microsoft Excel, then re-copy from that program and paste into the RAS Mapper attribute table.

RESOLVED

Infiltration Layer not Recognized

When creating a new Infiltration layer, the Infiltration layer is not recognized by the Layer Association dialog. Workaround: Edit the Infiltration.hdf file in HDFView and rename the "LC Type" attribute on the root of the file from "LandCover" to either "InfiltrationDeficitConstantLoss", "InfiltrationSCSCurveNumber", or "InfiltrationGreenAmpt" . Workaround: Create the Infiltration layer in RAS 6.4.1.

RESOLVED

Soils Layer not Recognized

When creating a new Infiltration layer, the Soils layer is not recognized in the Create New Infiltration dialog. Workaround: Edit the Soils.hdf file in HDFView and rename the "LC Type" attribute on the root of the file from "LandCover" to "Soils". Workaround: Create the Soils layer in RAS 6.4.1.

RESOLVED

Slope from Measure Tool Incorrect

The RAS Mapper measure tool is reporting incorrect slope measurement. Workaround: Cut a profile of the terrain, subtract first elevation from last elevation in the table.  Divide by the last station in the table.

RESOLVED

Simplified physical breaching erodes immediately to max depth.

In at least one data set, the simplified physical breaching algorithm widens at the user-specified pace...but erodes vertically to the max extent almost immediately.

IN PROGRESS

DL Breach computes rapid breaching width

There seem to be several issues with the current release of the DLBreach call from HEC-RAS.  We are actively working on these.

IN PROGRESS

Sediment Transport Capacity Calculator

The sediment transport capacity calculator (in the Hydraulic Design editor) computes bad values if some of the cross sections are included in the "Sediment Reach." Workaround: Select all of the cross sections in the Sediment reach.  The tool appears to work if all of the cross sections are selected.

IN PROGRESS

1D elements are not computing infiltration losses when finite volume solution is used

1D elements are not computing infiltration losses when the finite volume method is selected. This will result in the total precipitation entering the 1D system, not excess precipitation. 

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.

View Discussion

1 RESOLVED - issues are fixed and will be available in the next release.
2 IN PROGRESS - issues are currently being worked on.
3 IMPROVED - the next version includes an incremental improvement but not a total fix.
4 FUTURE VERSION - this requires a structural change or major development. The team will add it to a future version if funding permits.
