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 ...
Flood control, flood protection, flood defence and flood alleviation are all terms that mean "the detention and/or diversion of water during flood events for the purpose of reducing discharge or downstream inundation". [8] Flood control is part of environmental engineering.
The word "flood" comes from the Old English flōd, a word common to Germanic languages (compare German Flut, Dutch vloed from the same root as is seen in flow, float; also compare with Latin fluctus, flumen), meaning "a flowing of water, tide, an overflowing of land by water, a deluge, Noah's Flood; mass of water, river, sea, wave".
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

County flood control was first founded in an effort to control the wild waters of the Arroyo Seco and Charles Lummis founded the Arroyo Seco Foundation in 1905 for the purpose of preserving recreational use and habitat, residents in Los Angeles and Pasadena contributed generously to efforts to buy up open space in the ...
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
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.
The bond has about 1.5 time the money for wildfire and forest resilience needs, for example, than flood control. “The (climate change) problem is so big, people don’t know where to start half ...
