摘要:
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).

A method of influencing a flow of waste water in the waste water system of a housing development, in particular for reducing peak flows in these waste water systems. Reservoirs in the waste water system are activated in a surface-covering manner in order to delay discharge.
摘要:
For the purpose of effecting a quasi-permanent raising of the normal water level of an impounded reservoir and thereby augmenting its storage capacity except during the passage of major floods, the invention consists of rigidly fixing to the sill of the spillway a water level raising means comprising at least one vertical plate capable of resisting the water loads when spilling moderate heads (for discharging the floods of shorter recurrence intervals) but bending at its lower portion where it is fixed to the sill at a predetermined head not higher than the maximum water level in order to discharge larger floods.

A levee and barrier module for fluid control and containment is provided including an outer module shell and a module-to-module connection system to attach adjacent outer shells. The outer module shell is formed by opposing side walls and two opposing end walls and is configured to enclose or support filler material. The outer module shell defines a top aperture and a bottom aperture. The bottom aperture allows filler material communication with the earth below the module. The top aperture allows filler material to be added to the module, as well as visual observation of, and maintenance of, the amount of contained filler material. A presented application is directed to protecting pipelines and to allowing pipeline integration or association with levees.
摘要:
This device for triggering the destruction of a selected portion (1 or 11) of a hydraulic structure such as an embankment dam, dike, or levee built out of erodible material so as to be destroyable by hydraulic erosion is constituted by at least one massive element (5) which is disposed on the top of the selected portion (1, 11) of the structure and which is held there by gravity, the massive element (5) being dimensioned in size and in weight in such a manner as to be expelled by the water when it reaches a predefined level (N), the vertical dimension of the massive element measured beneath said predefined level (N) being selected in such a manner that the nappe which is released after the massive element has been expelled is of a thickness (z) suitable for causing reliable and rapid destruction of the selected portion (1, 11) of the hydraulic structure.
