Restoring floodplains can help regulate flood events and mitigate flood related damage. [6] Floodplain restoration can also increase biodiversity by creating new or restoring degraded habitat and encourage growth of native species. [7] [8] Methods of wetland restoration in the floodplain, can help better water quality. [9]
The Muskingum Watershed Conservancy District (MWCD) is a political subdivision of the State of Ohio organized in 1933 to develop and implement a plan for flood reduction and water conservation in the Muskingum River watershed, the state's largest wholly contained watershed, covering more than 8,000 square miles (21,000 km 2).
Robinson Creek in Boonville, California, had highly eroded stream banks prior to initiation of a stream restoration project.. Stream restoration or river restoration, also sometimes referred to as river reclamation, is work conducted to improve the environmental health of a river or stream, in support of biodiversity, recreation, flood management and/or landscape development.
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 ...
The peak flood level occurs as a very steep, short spike; a quick spurt of water. Anything that slows the surface runoff (marshes, meanders, vegetation, porous materials, turbulent flow, the river spreading over a floodplain) will slow some of the flow more than other parts, spreading the flow over time and blunting the spike. Even slightly ...
The Hidden Valley floodplain restoration project is adjacent to a restored section of Dos Rios, in the foreground, west of Modesto, Calif., Thursday, Feb. 29, 2024.
A restoration plan began in 1999 with the goals of reestablishing ecological integrity of the river-floodplain system. [20] The project involves dechannelizing major sections of the river, directing water into reconstructed channels, removing water control structures, and changing flow regimes to restore seasonal flooding to the floodplain.
