| Description: | Reference volume of water in the storage |
Water Storage Reference Volume is used to estimate storage level as a function of storage volume when the cross section area of the storage may not be constant. Along with Reference Level, the user inputs tranches of coordinate points that will be used to fit the polynomial equation:
Storage Level = p3*Storage_Volume3 + p2*Storage_Volume2 + p1*Storage_Volume + p0
