Evaluation

The pool elevation argument is looked up in the Pool Elevation column, of the Unregulated Spill Table, of the reservoir object argument, to determine the Unregulated Spill . If the exact elevation is not in the table, the lookup performs a linear interpolation between the two nearest bounding elevations and their corresponding unregulated spills.

Mathematical Expression

Comments

If the object is not a reservoir, or the reservoir does not have an Unregulated Spill Table , the function aborts the run with an error ( UnregulatedSpillCalc , RegPlusUnregSpillCalc , RegPlusBypass PlusUnregSpillCalc , or Bypass, Reg, and Unreg Spill must be selected as the Spill Calculation Category selected Method).
