Steady-state (constant) river water depth

When running a steady-state simulation that includes SZ-river exchange, a constant water depth may be specified for the river network, which can be used to calculate the head gradient driving the exchange flow.

If a constant river water depth is not specified, then the river water levels are determined in the following order

1.       MIKE SHE hot-start water level, if MIKE SHE hot-start is specified

2.       Initial water levels from MIKE Hydro River, if the MIKE Hydro River cou­pling is used

3.       Water level equal to the river bed if not 1) or 2) - (i.e. dry river - no flow from the river to the aquifer).
