Kanawha Falls
Kanawha Falls is a waterfall on the Kanawha River in West Virginia that has been a barrier to fish movement for more than 1 million years. The waterfall is formed by a diagonal sandstone ledge across the river about downstream from the confluence of the New and Gauley rivers. It is high. A low concrete overflow dam built in 1920 along the crest of the falls directs part of the flow to an electric generating plant on the western (right) bank of the river at the community of Glen Ferris. The plant was rehabilitated beginning in 2010 and fully returned to operation in 2012. The community of Gauley Bridge is upstream from Glen Ferris along U.S. Route 60. On the eastern (left) bank, a community named Kanawha Falls is about downstream. Kanawha Falls is the upstream limit of several fish species that broadly inhabit the Ohio River watershed. Above the waterfall, the watershed has fewer fish species overall, a relatively high number of species found nowhere else in the world, ...

Mississippi River System
The Mississippi River System, also referred to as the Western Rivers, is a mostly riverine network of the United States which includes the Mississippi River and connecting waterways. The Mississippi River is the largest drainage basin in the United States. In the United States, the Mississippi drains about fifty-nine percent of the country's rivers. From the perspective of natural geography and hydrology, the system consists of the Mississippi River itself and its numerous natural tributaries and distributaries. The major tributaries are the Arkansas, Illinois, Missouri, Ohio and Red rivers. Given their flow volumes, major Ohio River tributaries like the Allegheny, Tennessee, and Wabash rivers are considered important tributaries to the Mississippi system. Before the Mississippi River reaches the Gulf of Mexico, it runs into its distributary, the Atchafalaya River. From the perspective of modern commercial navigation, the system includes the above as well as navigable inland wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
100-year Flood
A 100-year flood is a flood event that has a 1 in 100 chance (1% probability) of being equaled or exceeded in any given year. The 100-year flood is also referred to as the 1% flood, since its annual exceedance probability is 1%.Holmes, R.R., Jr., and Dinicola, K. (2010) ''100-Year flood–it's all about chance 'U.S. Geological Survey General Information Product 106/ref> For coastal or lake flooding, the 100-year flood is generally expressed as a flood elevation or depth, and may include wave effects. For river systems, the 100-year flood is generally expressed as a flowrate. Based on the expected 100-year flood flow rate, the flood water level can be mapped as an area of inundation. The resulting floodplain map is referred to as the 100-year floodplain. Estimates of the 100-year flood flowrate and other streamflow statistics for any stream in the United States are available.Ries, K.G., and others (2008) ''StreamStats: A water resources web application 'U.S. Geological Survey, Fac ...

Summersville Lake
Summersville Lake is a reservoir located in the US state of West Virginia. The lake is formed by a rock-fill dam (Summersville Dam) on the Gauley River, south of Summersville in Nicholas County. It is the largest lake in West Virginia, with of water and over of shoreline at the summer pool water level. Its maximum depth is 327 feet. Dam The lake was constructed between 1960 and 1966 by the United States Army Corps of Engineers in order to control flooding in an watershed along the Gauley River and the Kanawha River. At tall, long, and containing of dirt and rock, the dam itself is the second-largest rock-fill dam in the Eastern United States. President Lyndon B. Johnson dedicated both the dam and a new Summersville Post Office on September 3, 1966. Hydroelectric project In 2001, a two-year project was completed to harness the dam outflow for hydroelectric power generation. The power plant has a capacity to generate 80-\ megawatts of electricity at peak flow. Recreati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluestone Lake
Bluestone Lake is a flood control reservoir located on the New River near Hinton, West Virginia. At its normal pool level, Bluestone Dam impounds a stretch of the New and its tributary, the Bluestone River. Normally approximately in size, the lake can grow to over long at flood control pool. At higher water levels, the lake extends into Giles County, Virginia. Bluestone Dam The lake is formed by Bluestone Dam, a concrete gravity dam located just upstream of the confluence of the New and Greenbrier Rivers. The dam is high and long. The dam was authorized by Presidential Executive Order in 1935 and approved by the U.S. Congress in the Flood Control Acts of 1936 and 1938. Construction of the project was begun in early 1941, suspended in 1944 because of World War II. Work resumed in 1946, and completed for operational purposes in 1949. In recent years, it was discovered that Bluestone Dam would be unable to pass the Probable Maximum Flood possible at the site, which ...

Claytor Lake
Claytor Lake in Pulaski County, Virginia, is a , reservoir on the New River, created for an Appalachian Power Company hydroelectric project. It is named for W. Graham Claytor, Sr. (1886–1971) of Roanoke, Virginia, a vice president of Appalachian Power who had supervised the construction of the Claytor Dam, which created the lake. Three miles of Claytor Lake's shoreline is bordered by Virginia's Claytor Lake State Park. History In 1910, the New River Power Company began acquiring land on the New River south of Radford, Virginia for the impoundment for several hydroelectric dam projects. By 1925, these projects had been combined, and control of the project passed to Appalachian Power Company. The construction of Development No. 6, later called the Claytor Dam, began in 1937 and was completed in 1939. By the Spring of 1940, the New River was fully impounded, and Claytor Lake was formed. Claytor Dam is a concrete gravity dam, impounding an estimated storage capacity of 22 ... [...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 ...

Streamflow
Streamflow, or channel runoff, is the flow of water in streams and other channels, and is a major element of the water cycle. It is one component of the movement of water from the land to waterbodies, the other component being surface runoff. Water flowing in channels comes from surface runoff from adjacent hillslopes, from groundwater flow out of the ground, and from water discharged from pipes. The discharge of water flowing in a channel is measured using stream gauges or can be estimated by the Manning equation. The record of flow over time is called a hydrograph. Flooding occurs when the volume of water exceeds the capacity of the channel. Role in the water cycle Streams play a critical role in the hydrologic cycle that is essential for all life on Earth. A diversity of biological species, from unicellular organisms to vertebrates, depend on flowing-water systems for their habitat and food resources. Rivers are major aquatic landscapes for all manners of plants and animals. Ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New River Gorge National Park And Preserve
The New River Gorge National Park and Preserve is a unit of the United States National Park Service (NPS) designed to protect and maintain the New River Gorge in southern West Virginia in the Appalachian Mountains. Established in 1978 as a national river and redesignated in 2020, the park and preserve stretches for from just downstream of Hinton to Hawks Nest State Park near Ansted. The park is rich in cultural and natural history, and offers an abundance of scenic and recreational opportunities. New River Gorge is home to some of the country's best whitewater rafting, mainly from the Cunard put-in to the Fayette Station take-out, and is also one of the most popular climbing areas on the East Coast. The New River itself originates in North Carolina, flowing north through Virginia into the West Virginia mountains to the Kanawha River which continues to the Ohio River.

Rafting
Rafting and whitewater rafting are recreational outdoor activities which use an inflatable raft to navigate a river or other body of water. This is often done on whitewater or different degrees of rough water. Dealing with risk is often a part of the experience. This activity as an adventure sport has become popular since the 1950s, if not earlier, evolving from individuals paddling to rafts with double-bladed paddles or oars to multi-person rafts propelled by single-bladed paddles and steered by a person at the stern, or by the use of oars. Rafting on certain sections of rivers is considered an extreme sport and can be fatal, while other sections are not so extreme or difficult. Rafting is also a competitive sport practiced around the world which culminates in a world rafting championship event between the participating nations. The International Rafting Federation, often referred to as the IRF, is the worldwide body which oversees all aspects of the sport. Equipme ...

Barge
Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges. History of the barge Etymology "Barge" is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek ''baris'' "Egyptian boat", from Coptic ''bari'' "small boat", hieroglyphic Egyptian D58-G29-M17-M17-D21-P1 and similar ''b ...

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which Erosion, erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.
