1. Control Structure Types
MIKE 11
Underflow Gate (Sluice Gates)
Overflow Gates (Inflatable Dams and Movable Weirs)
Radial Gates (Dam Spillways)
Discharge Control (Pumps)

4. Control Rules
MIKE 11
Control of a structure is implemented with a control Strategy
A strategy consists of a:
A control definition
A control rule
Logical statements that define the conditions for implementing the strategy.
The settings or Target Point for the structure as a function of the Control Point.

6. Control & Target Points
MIKE 11
A Control Point is the variable used to determine the target function.
Examples include:
Flood levels
Reservoir Inflows
Time of year
A Target Point is the variable you are trying to set.
Examples include:
Gate Level
Reservoir Water Level
Water level (H)
Water level difference (dH)
Discharge (Q)
Discharge difference(dQ)
Sum of discharges
Velocities (V)
Volumes
Concentrations
Calendar
Time-series
