Reach
In RPL Optimization, a constraint is always created to ensure mass balance. This constraint takes the following form with actual values or expressions comprising the variables shown, being dependent on the configuration of the reach object:
(5.34) 0 =
Inflows - Outflow + Return Flow - Diversion
Inflows may include Inflow, Local Inflow, time lagging effects, and GainLoss consideration.
Return Flow and Diversion may be excluded, if model configuration does not require usage of the terms.
General Slots
Inflow
Type: Agg Series
Units: Flow
Description: flow at entrance to the object
Information:
Defined by: Explicit Optimization variable in the mass balance constraint
Outflow
Type: Agg Series
Units: Flow
Description: flow at exit from the object
Information:
Defined by: Explicit Optimization variable in the mass balance constraint
