GSSHA sediment discharge modeling

Recommended Posts

Dear all,

Anyone who has tried GSSHA for sediment discharge modeling? I specified all the required parameters but I always get the following error:

Error: Attempting to allocate array of size 0

Error allocating memory for variable ch_wash_vol

Hope someone can help me. Im using GSSHA version 3.0a through WMS 8.0

Best regards,

Ariel

Hi Ariel,

There are a few resources that might be of some help to you. First, there is a GSSHA "Wiki" site that contains all the latest documentation for the GSSHA model. This is located at: http://gsshawiki.com. This site has a download of the latest development version of GSSHA, version 4.0a. Second, you can try sending an e-mail to the GSSHA developers at ERDC with your problem, but no response is guaranteed. Here is the GSSHA website with contact information at ERDC: http://chl.erdc.usace.army.mil/gssha. Finally, if you contact Aquaveo's tech support team, we might be able to look at your model and see if we can track down the problem. Visit our web site at http://www.aquaveo.com for more information about how to get tech support.

Regards,

Chris

Hi Chris,

Thanks for you reply.

I recently got a reply from Chuck Downer. he sent me a cmt file. The cmt file produced by WMS 8.1 lack some parameters for soil erosion, TC_COEFF and TC_INDEX i think. I edited my cmt file and now GSSHA sediment is working.

Also, even if I select sediment flux and sediment deposition to be two of the grid outputs, WMS wont give extension filenames for these. Even if I manually specified, the saved prj file does not contain any card for these desired outputs. When I open the saved GSSHA prj file, the check box for the sediments becomes unchecked.

I contacted Aquaveo's tech support weeks before but got a reply that technical support is no longer available for GSSHA.

Best regards,

Ariel
