These sizing equations are suggested for use in calculating the capacity of swales which have a larger proportion of surface flow. i.e. grass swales, rather than [[bioswales]]. <br>

In many cases the length of swale required will exceed the available space, so that an underground [[infiltration trenches|infiltration trench]] or a [[Dry ponds| dry pond]] will be a preferred solution.
