→To calculate the required storage reservoir footprint area where the depth is fixed or constrained (1D drainage)
In many locations there may be a limited depth of soil available above the seasonally high water table or top of bedrock elevation into which stormwater may be infiltrated. In such cases the required storage needs to be distributed more widely across the landscape. <br>

Where the storage reservoir depth is fixed or constrained the footprint area of the water storage reservoir, A<sub>r</sub> can be calculated:
Where the storage reservoir depth is fixed or constrained the footprint area of the water storage reservoir, A<sub>r</sub> can be calculated:
<math>A_{r}=\frac{i \times D \times Ai}{n\times d_{r}+f'D}</math>
<math>A_{r}=\frac{i \times D \times Ai}{(n\times d_{r})+f'D}</math>
