Floodwall
A flood wall (or floodwall) is a primarily vertical artificial barrier designed to temporarily contain the waters of a river or other waterway which may rise to unusual levels during seasonal or extreme weather events. Flood walls are mainly used on locations where space is scarce, such as cities or where building levees or dikes (dykes) would interfere with other interests, such as existing buildings, historical architecture or commercial use of embankments. Flood walls are nowadays mainly constructed from pre-fabricated concrete elements. Flood walls often have floodgates which are large openings to provide passage except during periods of flooding, when they are closed. As a flood walls mostly consist of relatively short elements compared to dikes, the connections between the elements are critical to prevent the failure of the flood wall. The substantial costs of flood walls can be justified by the value of commercial property thus protected from damage caused by flooding. ...

Portsmouth, Ohio
Portsmouth is a city in and the county seat of Scioto County, Ohio, United States. Located in southern Ohio south of Chillicothe, it lies on the north bank of the Ohio River, across from Kentucky, just east of the mouth of the Scioto River. The population was 20,226 at the 2010 census. Portsmouth also stands as the state's 88th most populated city. History Foundation The area was occupied by Native Americans as early as 100 BC, as indicated by the Portsmouth Earthworks, a ceremonial center built by the Ohio Hopewell culture between 100 and 500 AD. According to early 20th-century historian Charles Augustus Hanna, a Shawnee village was founded at the site of modern-day Portsmouth in late 1758, following the destruction of Lower Shawneetown by floods. European-Americans began to settle in the 1790s after the American Revolutionary War, and the small town of Alexandria was founded. Located at the confluence, Alexandria was flooded numerous times by the Ohio and the Scioto r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Williamson, Kentucky
South Williamson is a census-designated place (CDP) in the Appalachian Mountains of northeastern Pike County, Kentucky, United States, on the border with West Virginia. It is separated from Williamson, West Virginia by the Tug Fork River. The community is located near U.S. Route 119 about east of Pikeville, Kentucky and southwest of Logan, West Virginia. The South Williamson area includes the surrounding Kentucky communities of Goody, Forest Hills, Toler, and Belfry.

Levee
A levee (), dike (American English), dyke (Commonwealth English), embankment, floodbank, or stop bank is a structure that is usually earthen and that often runs parallel to the course of a river in its floodplain or along low-lying coastlines. The purpose of a levee is to keep the course of rivers from changing and to protect against flooding of the area adjoining the river or coast. Levees can be naturally occurring ridge structures that form next to the bank of a river, or be an artificially constructed fill or wall that regulates water levels. Ancient civilizations in the Indus Valley, ancient Egypt, Mesopotamia and China all built levees. Today, levees can be found around the world, and failures of levees due to erosion or other causes can be major disasters. Etymology Speakers of American English (notably in the Midwest and Deep South) use the word ''levee'', from the French word (from the feminine past participle of the French verb , 'to raise'). It originated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parkersburg, West Virginia
Parkersburg is a city in and the county seat of Wood County, West Virginia. Located at the confluence of the Ohio and Little Kanawha rivers, it is the state's fourth-largest city and the largest city in the Parkersburg-Marietta-Vienna metropolitan area. The population was 29,749 at the 2020 census. The city is about south of Marietta, Ohio. The Baltimore and Ohio Railroad reached Parkersburg in 1857, but lacked a crossing over the Ohio River until after the American Civil War. When the B&O completed the Parkersburg Bridge (CSX) 1868–1870 to Belpre, it was the longest railroad bridge in the world. The Bureau of the Public Debt, an agency of the U.S. Treasury Department, was relocated from the Washington, D.C. metropolitan area in the late 20th century and headquartered in Parkersburg. In October 2012, it was merged with the Financial Management Service to form the Bureau of the Fiscal Service. History Settlers at first named the city Newport when they settled it in ...

Floodgate
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. Since most of these devices operate by controlling the water surface elevation being stored or routed, they are also known as crest gates. In the case of flood bypass systems, floodgates sometimes are also used to lower the water levels in a main river or canal channels by allowing more water to flow into a flood bypass or detention basin when the main river or canal is approaching a flood stage. Types Valves Valves used in floodgate applications have a variety of design requirements and are usually located at the base of dams. Often, the most important requirement (besides regulating flow) is energy dissipation. Since water is very he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flood
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting i ...
