Remote Flow Control

Remote flow controls are logical relationships between a Reservoir and one or more flow control points downstream from the Reservoir, possibly with many intermediate inflows and offtakes.

To connect a Reservoir to a remote flow control point, click the ‘Add connec­tion’ button under the Reservoirs ribbon in Map view. Connect the Reservoir to the desired downstream point (anywhere on downstream Branches, but not Water users). A regular River node is automatically inserted on the desired flow control point and adds the Remote flow control to the Reservoir properties. A Reservoir can have multiple Remote flow connections.

Under the Remote flow control tab minimum or maximum remote flow requirements can be specified.

To add a minimum or maximum flow requirement to a remote flow connec­tion, enable ‘min. flow requirement or max. flow requirement’, click on

the  button and click Browse... to include an existing flow requirement time series or click Create a new file… to open the ‘Create a new file’ dialog.

During simulation, MIKE HYDRO will try to adjust the reservoir releases to meet the remote flow requirements after considering all inflows, extractions and flow delays due to routing. If the adjusted minimum reservoir release (to meet the remote flow requirements) is higher than a specified minimum release requirement for the reservoir, the adjusted reservoir release deter­mines the actual minimum reservoir release. Similarly, if the adjusted maxi­mum reservoir release (to meet the remote flow requirements) is lower than a specified maximum release requirement for the reservoir, the adjusted reser­voir release determines the actual maximum reservoir release.
