with MIKE 11

Detailed information on the MIKE 11 Water Quality modules are found in the MIKE 11 documentation.

The coupling between MIKE 11 and the rest of MIKE SHE’s hydrologic pro­cesses is relatively automatic. You must set up a MIKE 11 WQ model inde­pendent of MIKE SHE and specify this .sim11 file in the Rivers and Lakes dialogue. This .sim11 file must only have the same network geometry as the WM .sim11 file. It does not have to be the same .sim11 file.

The MIKE 11 WQ model can also include MIKE ECO Lab, which will allow you simulate eutrophication, etc. in the surface water.

There are a few caveats/limitations that you need to be aware of:

·         Species names must be identical in MIKE SHE and MIKE 11. If they are not identical, then the solutes will be transferred to the river as an infinite sink, but will not be transported in MIKE 11.

·         The overland WQ must be included if you want to simulate water quality coupled to MIKE 11.

·         Recycling of WM results is not supported in MIKE 11. This means that if you want to simulate the coupling between MIKE 11 and the rest of MIKE SHE, your WQ simulation must be continuous.
