|colspan = 2|The Curves table is designed to accommodate ponds of roughly conical dimensions. Rainwater cistern are usually cuboid or cylindrical in shape, so that the area (m<sup>2</sup>) will remain the same throughout the depth. The top and bottom dimensions can be placed within the first two rows of the table.
