In these examples an upstream large reservoir is considered, whose water level Hreservoir is constantly 3 m throughout the test. At the end of the last pool there is a control structure with an orifice offtake and a pump station. The flow through the orifice depends on the level over the orifice and the disturbance is introduced by the pump station. This is the downstream boundary condition. This example starts from an initial steady state (Tables 4 and 5) with a specific demand delivery constant at the end of the pool (5 m3/s through the orifice offtake), and the disturbance is not introduced initially.
