GetHuf_Average_Sy(Head, {Layer, Row, Column}) returns the weighted average specific yield of a cell based on all the hydrogeologic units intersected by the cell. However, HUF will not use this value. It uses the specific yield of the hydrogeologic unit that contains the current water table. GetHuf_Average_Sy is used to help display an approximation of how the HUF geometry and parameters ultimately control the specific yield of the cells.

The "Head" used in this function helps determine the thickness of the hydrogeologic unit in convertible layers. If the head is below the top of the unit in a convertible layer, the thickness of the unit is reduced.

GetHuf_Average_Sy can only be used in the formulas for data sets.

GetHuf_Average_Sy is used in the formula for the optional data set HUF_Average_SY.
