HEC-RAS 6.0 beta 2 is now available!
The beta 2 release of HEC-RAS 6.0 is now available. This fixes the bug with 2D bridges in SI…
This is a common question. It’s often desirable to have a table of timing for peak stages and flows for dam breach models. This allows you to track the arrival of the flood wave at all locations downstream of the dam. However, the typical output plots in HEC-RAS are not very helpful in providing this information. You could look at each cross section’s stage and flow hydrograph, and pick off the time for the peaks, but this can be very tedious and time-consuming. There is a much faster way to get this information using the DSS Viewer in HEC-RAS.
Go to the DSS viewer on the main RAS window.
Once there, filter the records as follows by clicking in the blank cell at the top of each column and selecting what you want to see from the dropdown box:
Part A: Select the Reach you want to look at
Part B: Leave Blank
Part C: Select LOCATION-TIME
Part D: Leave Blank
Part E: Select MAX STAGE or MAX FLOW
Part F: Select the Plan you want to view.
Once you have the record you’re interested in, double click it in the filter table so that it is brought down to the list box at the bottom. Then highlight the record in the list box and click “Plot/Tabulate Selected Pathname(s). You should see a graph that plots out the Simulation Time for Max Flow or Stage for every cross section in the selected reach.
