Dry dam - Wikipedia
WEBA dry dam is a dam constructed for the purpose of flood control. Dry dams typically contain no gates or turbines, and are intended to allow the channel to flow freely during normal conditions.
Flood Mitigation: Dry Dams - Alberta WaterPortal
WEBFeb 24, 2014 · What is a dry dam? Dry dams are catchment areas that have been designed to hold excess water in times of flooding and allow water to move freely in normal conditions. This is a short term flood mitigation solution that stores water for approximately 24 to 48 hours before slowly releasing the water to prevent downstream flooding.
Build and maintain retention and detention basins
WEBThese detention basins, often referred to as “dry dams,” require engineering analyses to determine the appropriate size for the drainage area and specific construction techniques needed to avoid failure.

WEBJun 15, 2023 · Passing by the dry-bed reservoir causes some people to think the dam is broken. Although the reservoir does not maintain a permanent water pool, the dam functions as designed to retain excess...
Dam - Wikipedia
WEBA dry dam, also known as a flood retarding structure, is designed to control flooding. It normally holds back no water and allows the channel to flow freely, except during periods of intense flow that would otherwise cause flooding downstream.
Isn't "dry dam" an oxymoron? - Moore Engineering, Inc.
WEBDec 3, 2015 · A dry dam only holds water during flood events. After the flood waters recede, the storage area drains completely dry again. This is opposed to a “wet” dam, where at least some water is permanently stored in …
Flood Control Capability of Dry Dams Constructed in Series
WEBMultiple small dry dams (which lack a slide gate in the spillway) are constructed in series rather than a single large dam in order to prevent flood disasters and to preserve the natural environment. Dry dams for flood control have recently been reviewed, planned, and built at some sites in Japan.
