Floodplain Mapping of Unsteady Profile

[Travis Williams]

I am working with a project using unsteady flow. I prepared the geometry in RivercadXP and exported it to hec-ras for unsteady analysis. Now I would like to import the "MAX" water surface profile back into Rivercad to use the floodplain mapping module. Is this possible and if so how is it accomplished?

Thanks in advance.

Real simple.

From the Floodplain Mapping Module, select Floodplain | Define Floodplain Data. RiverCAD will then display the Define Floodplain Data dialog listing all of the cross sections in the river reach.

Select the Import button, and read-in a simple ASCII text file that has two columns of data:

- Cross Section ID
- Maximum Water Surface Elevation

No header is required in the file.

Here is a sample (included in the Examples folder, called WABASH.FPM):

29500 7.00
30000 8.08
30500 9.42
31000 10.58
31500 11.53
32000 12.93
32500 13.73

If the file has the extension *.FPM, RiverCAD will automatically recognize it.

We are changing the Define Floodplain Data dialog so that you can simply copy and paste directly and there will no need to create the ASCII file.

If you have any additional questions or need any further information, please contact me again.
