Exporting Model Output Alternatives

[Anonymous]

I am looking for options/ideas for methods to analyze and plot data outside of HEC-RAS. I am going to be working on a large model and I would like to have some code setup in program R so I can import HEC-RAS model runs, quickly make plots of desired reaches with specific flow profiles, and also make direct quantitative comparisons between different model runs.

Can someone point me in the right direction of how I can quickly export HEC-RAS model results data to tabular format with going through the GUI in the main output windows? Ideally, I would like to run the model and have an output that is a table of each XS and all possible output variables as a comma delimited text file. Any advice would be appreciated.

Are you running steady flow or unsteady flow? Unsteady flow writes out the output hydrographs to DSS and you could write a program to read DSS directly using a C or Fortran program.

The other option is to use the “RAS controller” option. I haven’t tried this, but I”ve read discussions on it from time to time. For instance:
http://hec-ras-help.1091112.n5.nabble.com/HEC-RAS-in-Batch-Mode-td3.html

The Beta 5 version of RAS has output using HDF5. This might provide an easier method of getting output.
