Because of its numerical limitations, MIKE 11 cannot model the supercritical
flow downstream of the weir.
For the low-flow case, the downstream water level is over-estimated by
a factor of 8 .This high tailwater, impacts on the flow conditions on the
weir, causing a significant error in the upstream water level.
The incorrect tailwater has less impact for the high-flow case. There is
still significant error in the predictions across the weir, but the upstream
water level is almost correct.

overland flow,
infiltration into soils,
evapotranspiration from vegetation, and

Integrated:
Fully dynamic exchange of water between all major hydrological components is
included, e.g. surface water, soil water and groundwater
Physically based:
It solves basic equations governing the major flow processes within the study area
Fully distributed:
The spatial and temporal variation of meteorological, hydrological, geological and
hydrogeological data
Modular:
The modular architecture allows user only to focus on the processes, which are
important for the study
