Water balance with MIKE Hydro River

The water balance tool in MIKE SHE (Using the Water Balance Tool (V1 p. 95)) includes the exchange with MIKE Hydro River, but it does not include the water balance within MIKE Hydro River. In other words, once water enters MIKE Hydro River it is no longer part of the MIKE SHE water balance. Thus, there are numerous water balance items that detail the different exchanges to and from MIKE Hydro River.

Water exchanges within MIKE Hydro River can be evaluated using the MIKE View tool. In some cases, this may require you to include the additional out­put for MIKE Hydro River, which is selected in the Additional Output tab in MIKE Hydro River’s HD editor.

Note: output in MIKE Hydro River is instantaneous, whereas the output in MIKE SHE is generally accumulated within a time step. Therefore, a flow at a rate at a point in MIKE Hydro River (e.g. a weir) will be the instantaneous flow at the end of the time step. In MIKE SHE, however, the flow into a cell will be the average flow over the time step.
