Links: May be linked to the Pumped Flow slot of a Pumped Storage object.
Inflow
Type: Multi Slot
Units: FLOW
Description: inflow into the reservoir from upstream
Information:
I/O: Optional; if not input by the user, it is set through either mass balance computations or the propagation of values across the link.
Links: May be linked to one or more outflow slots of upstream objects.
Max Iterations
Type: Table
Units: NOUNITS
Description: maximum number of allowable iterations for iterative loops in the solution algorithms
Information: Used in conjunction with Convergence Percentage as a stopping criterion for iterative calculations.
I/O: Optional; defaults to 100 if not input.
Links: Not linkable
Max Release
Type: Table
Units: LENGTH vs. FLOW
Description: reservoir pool elevation vs. maximum release through controlled outlet-conduit of a reservoir (excluding spill)
Information:
I/O: Required input
Links: Not linkable
Outflow
Type: Series Slot
Units: FLOW
Description: outflow from reservoir
Information: The Outflow from a Storage Reservoir is equal to the sum of the Release and the Spill.
I/O: Optional; if not input by the user, it is set through either the mass balance computations or the propagation of values across the link.
Links: May be linked to the inflow slot of a downstream object.
Pool Elevation
Type: Series Slot
Units: LENGTH
Description: elevation of the water surface in the reservoir
Information: There must be an initial value for either Storage or Pool Elevation given by the user for the first timestep.
I/O: Optional; if not input by the user, it is solved by the mass balance computations. It may take a TARGET flag indicated by the user for target operation solution.
Links: May be linked to Tailwater Elevation or Tailwater Base Value of an upstream object or to Elevation 1 or Elevation 2 of a Canal object.
Release
Type: Series Slot
Units: FLOW
Description: Flow through the outlet-conduit of a storage reservoir (excluding spill)
Information:
I/O: Optional; solved for if not input.
Links: Usually not linked
Return Flow
Type: Multi Slot
Units: FLOW
Description: Flow returning from a diverting object
Information:
I/O: Optional; defaults to zero if not linked or input.
Links: May be linked to one or more Return Flow slots on Water User objects or the Total Return Flow slot on the Agg Diversion Site objects.
Spill
Type: Series Slot
Units: FLOW
Description: Sum of the regulated and unregulated spills and bypass
Information:
I/O: Optional; may be input or solved for by RiverWare (see spill calculation methods).
Links: Usually not linked
Storage
Type: Series Slot
Units: VOLUME
Description: volume of water stored in the reservoir
Information: This slot may be flagged as a TARGET storage value by the user. If flagged as a TARGET, a target operation solution is used.
I/O: Optional; if not input by the user, it is set through mass balance computations.
Links: Usually not linked
Total Inflows
Type: Series
Units: Flow
Description: Summary slot displaying the flows into and out of the reservoir excluding the flows through the outlet works
Information: Total Inflows is calculated. Any component that is not in use or is not valid defaults to zero.
I/O: Output only
Links: Not linkable
Inflow Sum
Type: Series
Units: Flow
Description: Sum of the total flows entering the reservoir at each timestep
Information: Inflow Sum is calculated.
I/O: Output only
Links: Not linkable
Note: Either the initial (Beginning of Run) value for Pool Elevation or Storage must be input by the user.
