Cross Sectional Diagram of a Two Stage Drainage Ditch . A drainage ditch is a depression in the land created to channel water.Drainage ditches are typically formed around low-lying areas, roadsides or fields proximate to a water body or created to channel water from a more distant water source for the purpose of plant irrigation.
The map to the right shows a flood map for the City of York, including the floodplain for a 1 in 100-year flood (dark blue), the predicted floodplain for a 1 in 1000 year flood (light blue) and low-lying areas in need of flood defence (purple). The most sustainable way of reducing risk is to prevent further development in flood-prone areas and ...
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] Reconnecting rivers to their floodplains promotes carbon storage in soil and regulates processes within soil. [8]
A floodplain or flood plain or bottomlands [1] is an area of land adjacent to a river. Floodplains stretch from the banks of a river channel to the base of the enclosing valley, and experience flooding during periods of high discharge. [2] The soils usually consist of clays, silts, sands, and gravels deposited during floods. [3]
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). Since the original ...
The Great Flood of 1913 severely affected Columbus, Ohio. The area most affected was Franklinton, also known as the Bottoms, for its low elevation near the Scioto River. Among many infrastructure projects, a 7.2-mile floodwall was built from 1993 to 2004 to protect most of Franklinton from flooding.
Fluvial terraces are elongated terraces that flank the sides of floodplains and fluvial valleys all over the world. They consist of a relatively level strip of land, called a "tread", separated from either an adjacent floodplain, other fluvial terraces, or uplands by distinctly steeper strips of land called "risers".
[1] [2] Floods on the Mississippi, Ohio, and other rivers in the Northeast led to the Flood Control Act of 1917, which was the first act aimed exclusively at controlling floods. The Great Mississippi Flood of 1927 led to substantial flood control funding.
