This project concerns the computations required to determine the drawdown for the retention/detention of ponds. Drawdown refers to the volume of water in a pond that decreases as the water flows out. The falling head equation has many applications and can be used to calculate the drawdown of a pond through various shaped openings. https://www.ealisboa.com/best-offer-Duraflex-Circuit-Widebody-Fender-Flares-Fiberglass-Infiniti-G35-Coupe-Non-Sport-super-save/
