US 11,898,317 B2 · Surface water management system including weir wall and detention pond

Abstract

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.
