To estimate the depth of water that can be infiltrated into a surface within a given time::  
<math>y=f\times t</math>
After surveying the longitudinal profile of the swale, the number of check dams for the swale can be calculated by using the following equation:
:<math>Number\ of\ dams= \frac{L\left ( S_{i}-S_{e} \right )}{h}</math>
