SWAT+gwflow error basin.carbon.tes not found / hydrograph module floating overflow forrtl error 72

[Benthe]

Hi everyone,

Since this week I haven’t been able to run my SWAT+GWflow model successfully. The simulation runs for about 2 years and then stops with an error related to the hydrograph module (see error text below).

I’ve tried setting up the model again several times, but the problem persists. When I run the debug version (rev61), it also says that basin_carbon.tes cannot be found. However, I don’t see this file in any of the example projects provided in the tutorials, so I’m not sure if it should exist or not.

Could anyone help me understand what this error means and how to fix it? I’m a bit stuck and would really appreciate any suggestions or guidance.

Thanks in advance!

Benthe:

Please send your current txtinout and I will take a look at this for you. 

If the problem is in the gwflow model, I will forward to the developer for his review and comments.

Thank you,

Nancy
