The early release from wetlands and shallow ponds could provide extra water storage during heavy rainfall, thus mitigating floods. In this paper, a remotely operated integrated siphon system intended to release water from wetlands/shallow ponds ahead of (a few hours or a few days before) a heavy rainfall that is forecasted to produce flooding is proposed. Siphons work under the pull of gravity and are limited to pond berm heights below about 6 m. An array (e.g. hundreds) of the proposed siphon system can be controlled remotely by an operator or by a Decision Support System. A self-operating and remotely controlled siphon system could open the doors for managing wetlands and shallow ponds for multiple purposes, including flood control and improvement of aquatic habitat. Laboratory tests using 4 and 15 cm-diameter siphons were performed in this study. The results showed that the integrated control system is technically feasible and economically viable.
