custom code can be used to couple MODSIM with some hydrological model

Issue #31 invalid
Former user created an issue

I am just thinking to couple (two way coupling) MODSIM with hydrological model to feed with stream inflow. Do you think that can be possible in custom code editor or I have to use other tools like MATLAB. Do you have any example who did this before

    In this case there would be no purpose to a two-way coupling unless I'm misunderstanding your question. MODSIM would not provide any feedback that a hydrologic model such as VIC, PRMS, etc would use. It would be a one-way coupling where the streamflow (water supply) from the hydrologic model would be input into and regulated by MODSIM or MODSIM would control the water supplied to water users based on priorities. From my subset of knowledge, I don't think there is really any need for such a coupling. It is easy enough to run the hydrologic model separately and input the natural streamflow (water supply) into MODSIM.

    The coupling that is currently being explored in more depth is MODSIM (two-way coupling) with MODFLOW. To attempt to capture how regulation of surface flows interacts with groundwater and then the resultant groundwater response interacting with surface flows.

    But to answer your question globally. Yes, most any sort of MODSIM coupling is possible using custom code to interact with MODSIM's solution. When working with custom code we use Microsoft Visual Studio and C# as MODSIM is entirely written in C# now, the custom code editor is a quick start tool. I don't have any examples of the coupling you're talking about because I don't think people generally see it as a need. We instead run a hydrologic model separately and then input the resultant streamflow into MODSIM as I discussed above.

    Hope that is helpful.

    I want to control the reservoir operations like in this paper

    Sorry, I don't have access to that paper and from the little bit I can see I'm not quite following. They say, "For example, water abstraction for irrigation has a significant impact on the hydrological process." When they say "water abstraction" I think of groundwater pumping, and the hydrologic models I'm familiar with do not capture this. Maybe SWAT does but I'm unfamiliar with that application. One application that does attempt to account for deeper groundwater interactions is GSFLOW.

    Sorry again, I don't have any examples of this type of coupling. But like I mentioned before, most any sort of MODSIM coupling is possible using custom code.

    You might try contacting John Labadie directly (labadie@engr.colostate.edu) to see if he has any further information since he does not track the activity on this website since it mostly relates to the MODSIM source code.

    Closing this issue. There is no enhancement to MODSIM necessary, custom code can be used to interact with MODSIM's solution already.
