Witrynacomputed orifice size required to achieve the desired drawdown time may be small (less than three inches in diameter). These small openings are vulnerable to clogging … WitrynaTime = incremental drawdown time from Stage n to Stage n-1 dStor = change in storage from Stage n to Stage n-1 Qave = average outflow from Stage n to Stage n-1. As shown in the table below, it would take 3.49 hours for this particular pond to drawdown from Stage 0.35 feet. Hydrology Studio computes time to empty until the flow, Qave, …
