Exchange inflows reduced

Warning: Exchange inflows from Overland to MOUSE reduced by Overland house-keeping in order to avoid instabilities

No. of time steps:    27000 of 27000

Total a priori inflows:    1332286 m3

Total reduced inflows:     920643.0 m3 (69.10%)

MIKE SHE calculates tine in/out flows after an overland time step and feeds them to MIKE URBAN for one or more MIKE URBAN time steps. The calcula­tions of these flows are not included in the implicit overland flow solver. Thus, the “Total a priori flows” are the rough inflows calculated using Equation (32.1). However, to prevent water balance errors, MIKE SHE checks the vol­ume of water available in the grid cell. If the volume is insufficient, then the inflow is reduced to the available amount. The final value of inflows is the “Total reduced inflows”. Note though that the total NET inflow to MIKE URBAN will be less than this value if the flow goes from MIKE URBAN to MIKE SHE in other grid cells or other time steps.

Ideally, the Total reduced inflow should be 100%, but in practice this is rarely achieved.
