HEC-RAS 7.0.1 released

Major Issues

Issue

Description

Geometry pre-process error message "Cannot recompute 2D Property Tables - No Terrain is associated with this geometry".

When terrain files are not within the project folder, or in a subfolder of the project folder, users who run the geometry pre-processor will see this error message.  

Point Meteorology Broken Without Rasterization Parameters

Rasterization parameters in the Unsteady Flow Editor are needed in order for Wind and other point meteorology methods to pass the geometry preprocessor.  Also note that at least in metric datasets, Air Pressure point meteorology doesn't work at the moment. 

Cross Sections Using Mapping Output Report Incorrect Times in Hydrograph Plot

For cross sections using Mapping output (Hydr Or Map = Map), the plotted/reported times are incorrect because the data is labeled with Stage & Flow output times instead of Mapping output times.”.  

Maximum Water Surface Error Not Working Correctly

Summary result maps such as Maximum Water Surface Error may not work correctly if the model contains more than one 2D flow area.  

RASMapper Crashing on Startup

If there exists a snapshot with a summary result map, such as Maximum Water Surface Error, RASMapper may crash on startup.  

Hydrograph Plot - Metric datasets

For metric datasets, the output for the new Coordinated Plot and the Stage and Flow Hydrograph plot is not correct.  The Rating Curve is also incorrect.  The Stage in the Profile Plot is correct.

Unsteady Flow Hydrograph Plot - Multiplier

When using the Multiplier function on a boundary condition flow hydrograph, the Plot defaults to the extent of the base data.  

Cross Section Plot - 1D Velocity Distribution

1D Velocity Distribution Plot for Unsteady Flow models is not displaying the correct number of slices.  One velocity for the channel and each overbank is shown.

Run Multiple Plans

Index out or array crash if user adds additional Plans and attempts to run the plans a 2nd time.  

2D Property Tables Generation

2D hydraulic tables are unnecessarily built for mesh cells when there are edits to other geometry items such as modifying a hydraulic structure. 

2D Bridge Plots - Abutments

Bridge abutments not plotting in the new Coordinated Plot or Hydrograph Plot. 

Pipe System Name Duplication

The hydrograph plot will crash when attempting to launch with a result that has pipe networks names that only differ in case.   

Land Cover - Export 

Layer is not exported properly. Values are single precision - not integer. 

Final Manning's n Layer - Export

Layer is not exported properly. Values are rounded. 

2D Bridge Scour

An interface bug disabled 2D Bridge Scour in RAS 7.0.  This has been fixed and the new Bridge Scour updates will be available in 7.0.1.  The documentation has also been updated to reflect several updates and the new version (5.5) of the FHWA toolbox.

Plot Crashes - Calibration Regions

Models with multiple Calibration Regions that do not have corresponding 2D Flow Areas in the model will crash the new Coordinate Plot and Hydrograph Plot.  

Terrain Modifications - Export

New raster may have bottom portion (minimum Y-extent) of Terrain Modification missing - most notable for piers with triangular nose. 

Sediment Rating Curve Calculator

Version 7.0 had a bug that disabled the sediment rating curve calculator.  This has been fixed in version 7.0.1.

Minor Issues

Issue Description
 Fixed air pressure units bug that prevented simulation from running
Fixed a crash with the hydrograph plot when attempting to launch with a result that has pipe networks names that only differ in case
