HEC-RAS 6.3

IssueDescriptionStatus 1 2 3 4
Reference Lines - 1D Only crash

Reference lines are not allowed in a 1D only model. A runtime crash will ensue for models that have 1D elements only and Reference Lines.

IN PROGRESS

2D Bridge Curves Being Recomputed for Each Simulation

The rating curves for 2D bridges are unnecessarily being recomputed upon each simulation run. 

RESOLVED

Can't Complete Geometry When Number of Pump Stations Exceed Number of Structures of Any Type

If there are more pump stations in the model domain than total structures (inline, lateral, SA/2D, bridges) geometry property tables will not be able to complete, preventing a model compute. Workaround: Add dummy internal SA/2D structures until total number of structure equals or exceeds the number of pump stations. 

RESOLVED

Observed Data for Reference Points Not Plotting

Reference Points with Observed Data are not plotting in the hydrograph plot. (Version 6.2 is correctly plotting observed data.)

RESOLVED

Observed Data for Reference Lines Not Plotting

Reference Lines with Observed Data are not plotting in the hydrograph plot. (Version 6.2 is correctly plotting observed data.)

RESOLVED

Observed Data for Cross Sections Not Plotting

Cross Sections with Observed Data are not plotting in the hydrograph plot.

RESOLVED

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.

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.
