An integrated system comprising a barrier, such as a weir with movable gates, controllably blocks water flow in a natural or concrete lined channel. Without substantially impeding flow in normal conditions, the barrier is configured to back up flood waters to spill into an upstream prepared detention basin. Water is thus kept from downstream areas until subsequently drained through a controlled spill. Multiple units installed in a watershed can store significant amounts of flood water, e.g., during a hurricane, protecting life and property downstream.

The electromechanically-operated gates can be operated locally or from a remote control center. Gauges and sensors positioned near the weir and/or throughout the watershed can provide data used to control one or more barriers in the watershed, and the data may be used to train a machine learning model to control the system.

The present invention relates to a high water spillway (5) for barrages and similar structures, comprising a spill threshold (6), the crest of which is located at a first predetermined level (RN) lower than a second predetermined level (RM) corresponding to a maximum level or to the highest water level (PHE) for which the barrage (1) is designed, the difference between said first and second levels (RN and RM) corresponding to a maximum predetermined flow of an exceptional high water, and a fusegate (10) plugging the spillway (5), said gate (10) comprising at least one rigid and solid gate element (11), which is placed on the crest (8) and is held in place thereon by gravity, said gate element being imbalanced when the water reaches a third predetermined level (N) higher than the top of the gate element (11), but at most equal to the second predetermined level (RM). According to the invention, said spillway further comprises an aeration system that comprises at least one duct (20) capable of routing air towards the bottom of the jet discharged by the crest of said gate (11).
