Vertical Unsaturated Recovery Calculator
Estimate the vertical unsaturated recovery volume for a retention cum detention pond.
Using: \(\displaystyle V_{rec} = \frac{K_s \times A_{pond} \times H_{eff} \times t}{L_{unsat}}\)
* Enter the pond parameters along with recovery time. \(K_s\) is in ft/day, area in ft², head in ft, time in days, and unsaturated thickness in ft.
Step 1: Enter Parameters
Example: 2.0 ft/day
Example: 10,000 ft²
Example: 3 ft
Example: 1 day
Example: 5 ft
