BlockAreaTop({Column, Row}) is like BlockAreaFront except that the value returned is the cross-sectional area of an element or cell as seen from the top of the grid or mesh (fig. 23). The function has two optional arguments: Column and Row. If these arguments are provided, they specify the element or cell for which the area should be calculated. If they are not provided, the function uses the column, and row of the element or cell for which the formula is being calculated. If any of the arguments has an invalid value, the function returns zero.
For SUTRA and MODFLOW 6 DISV models, Row should always be 1 and Column represents the cell or element number.
Figure 23. For grids, BlockAreaTop returns the product of b times c.
