In your model you can have up to a total of 256 sources and sinks. The sources and sinks are then numbered in succession and you specify (or edit) each of them by giving the corresponding number.
For a source you specify:
· The source location is specified as a constant in time and space.
· The source direction of the flow is specified as a constant in time and space.
· The source discharge and flow speed can be specified as a constant in time and space or as a time series. The discharge is given in m3/s and the flow speed in m/s.
For the above specifications, the only requirement is that the source data be specified for the complete simulation period.
For a sink you specify:
· The location (in grid coordinates). The location is a constant in time and space.
· Either a constant intake (in m3/s) or the name of a data file as described for a source but with only one item, the intake discharge.
