Installation for combating flooding associated with spates of a waterway, including a mobile barrage, an acceleration station designed to pump water through or under the mobile barrage, from upstream of the mobile barrage to downstream when this barrage is in the active configuration, so as to increase the gradient of the stream upstream of the barrage and increase the flow rate.

In order to meet the objective of providing a device (10) and a method for a sediment transfer in waters (80, 81, 90) that works efficiently, a device (10) comprising at least one suction line (12) and at least one receiving means (16) for receiving sediment (70), and furthermore, having at least one pressure line (14) for transferring the received sediment (70) is proposed. Following the at least one receiving means (16), at least one pump device (18) and at least one measuring device (20) for determining a sediment concentration of the received sediment (70) are arranged. The device (10) further comprises a control unit (22) having a first interface (25) for inputting target values (24) and a second interface (26) for the at least one measuring device (20), and determines a sediment concentration in the at least one suction line (12) and/or in the at least one pressure line (14). Depending on the sediment concentration, a power of the pumping device (18) is adjustable.

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 method for protecting the ecology of a coastal mudflat and a system used in the method. The method includes the following steps: plan and design a pond project according to the specific conditions of the target coastal mudflat to be protected; dig a trench and build a dike in the surface of the target coastal mudflat and enclose the dike to form at least one pond, wherein the trench in the pond is adjacent to the surface of the mudflat to form the pond with a large water surface, a shallow water layer and a seasonal open waterfront; and cultivate an aquatic product in the trench, with or without an emergent aquatic plant planted in the surface of the mudflat.

A system for reducing contaminants in body of water is shown and described. The system has a first land mass located within a body of water. A sediment trap, located on the floor of the body of water, is configured to collect sediment. Enclosed within the first land mass is a tussock mass area, surrounding a central area, and configured for collecting sediment and building a second land mass. The central area of the system is configured for removing contaminants from sediment. Sediment is moved from the sediment trap to the central area by a first ingress conduit and a pumping system. Filtered water migrates from the central area to outside the first land mass via an egress conduit; contaminated sediment is sequestered in the central area enclosed by the tussock mass area.

A detention pond for the passive temporary storage of detained water during a potential flooding event near a river, stream or bayou where the depth and therefore the volume of the detention pond is not set by the elevation of the normally flowing water in said river, stream or bayou adjacent detention pond but rather the drain line connects to the river, stream or bayou downstream of the detention pond where the elevation is at a lower level, allowing the detention pond to be dug deeper and therefore of proportionately greater volume.
