*Five percent of the average annual yield can be estimated:
*<strong>Y<sub>0.05</sub>= A × C<sub>vol, A</sub> × R<sub>a</sub> × e × 0.05</strong>
*Y<sub>0.05</sub> = Five percent of the average annual yield (L)
*A = The catchment area (m<sup>2</sup>)
*C<sub>vol, A</sub> = The annual runoff coefficient for the catchment
*R<sub>a</sub> = The average annual rainfall depth (mm)
*e = The efficiency of the pre-storage filter
