Flood control channels are large and empty basins where surface water can flow through but is not retained (except during flooding), or dry channels that run below the street levels of some larger cities, so that if a flash flood occurs the excess water can drain out along these channels into a river or other bodies of water. Flood channels are ...
Structural flood management (i.e: flood control) is the reduction of the effects of a flood using physical solutions, such as reservoirs, levees, dredging and diversions. Non-structural flood management includes land-use planning , advanced warning systems and flood insurance.
Flood mitigation is a related but separate concept describing a broader set of strategies taken to reduce flood risk and potential impact while improving resilience against flood events. As climate change has led to increased flood risk an intensity, flood management is an important part of climate change adaptation and climate resilience .
The flood control strategies for the Sacramento and San Joaquin River Watersheds devised by the Central Valley Flood Protection Board, meanwhile, is a comparable pittance, at “only” $25 ...
Storm water is typically channeled to a retention basin through a system of street and/or parking lot storm drains, and a network of drain channels or underground pipes.. The basins are designed to allow relatively large flows of water to enter, but discharges to receiving waters are limited by outlet structures that function only during very large storm eve
The Los Angeles River is extensively channelized with concrete embankments.. River engineering is a discipline of civil engineering which studies human intervention in the course, characteristics, or flow of a river with the intention of producing some defined benefit.
Los Angeles County flood control network withstands punishing rains -- for now L.A.'s flood-control system survived epic storm. But it's losing battle with climate change
Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or storm surge system.
