Dickerson Whitewater Course
The Dickerson Whitewater Course, on the Potomac River near Dickerson, Maryland, was built for use by canoe and kayak paddlers training for the 1992 Olympic Games in Spain. It was the first pump-powered artificial whitewater course built in North America, and is still the only one anywhere with heated water. It remains an active training center for whitewater slalom racing, swiftwater rescue training, and other whitewater activities. The facility is owned by the NRG Energy company. Except during special events, access requires membership in the Potomac Whitewater Racing Center, a USA Canoe/Kayak National Training Center. The course was constructed in 1991, inside a pre-existing straight, -long concrete channel, wide. Since 1959, the channel has returned cooling water from the Dickerson Generating Station to the Potomac River, upstream from Washington, D.C. Water is pumped from the river, warmed as much as 35 °F (20 °C) as it cools the power plant's three coal- ...

Segre Olympic Park
Parc Olímpic del Segre is a canoeing and kayaking facility in La Seu d'Urgell, Catalonia, Spain, built in 1990 for use during the 1992 Summer Olympics in Barcelona. The competition whitewater course is 300 m long, with a 6.5 m drop, making a 2.2% slope of 114 ft/mile or 22 m/km. The natural flow of the Segre River is diverted through the course by a diversion dam upstream. In low flow conditions, four 300-kilowatt recirculation pumps can add up to 12 m3/s to the course flow, in order to increase it to the course maximum of 17.5 m3/s. When the course is not being used, or when the natural flow exceeds 17.5 m3/s, the pumps are reversed and run in turbine mode to generate electricity for the town. A 130-metre beginners course is a diversion from the main course. Its drop is 1.5 m for a 1.2% slope of 61 ft/mile or 12 m/km. Streamflow for the beginners course is 3 to 10 m3/s. The park also has a 650-m long feedwater canal which carries water from the river into the ...

Artificial Whitewater Courses
Artificiality (the state of being artificial or manmade) is the state of being the product of intentional human manufacture, rather than occurring naturally through processes not involving or requiring human activity. Connotations Artificiality often carries with it the implication of being false, counterfeit, or deceptive. The philosopher Aristotle wrote in his ''Rhetoric'': However, artificiality does not necessarily have a negative connotation, as it may also reflect the ability of humans to replicate forms or functions arising in nature, as with an artificial heart or artificial intelligence. Political scientist and artificial intelligence expert Herbert A. Simon observes that "some artificial things are imitations of things in nature, and the imitation may use either the same basic materials as those in the natural object or quite different materials.Herbert A. Simon, ''The Sciences of the Artificial'' (1996), p. 4. Simon distinguishes between the artificial and the synthe ...

Creeking
Creeking (sometimes called steep creeking or treetop boating or creekboating) is a branch of canoeing and kayaking that involves descending very steep low-volume whitewater. It is usually performed in specialized canoes and kayaks specifically designed to withstand the extreme whitewater environment in which the activity occurs. In addition, the canoes and kayaks give the paddler improved performance and maneuverability needed to avoid river obstacles. Description Creeking Creeking usually involves the descent of waterfalls and slides, but equally applies to any steep low volume river. Creek characteristics can vary greatly, from very smooth granite like Cherry Creek in California where there are no loose rocks and most features are slides and waterfalls, to boulder gardens such as the Stein River in British Columbia where rapids are formed between rocks with features including sieves (siphons), step drops, holes, and undercuts. Creeking tends to be more dangerous and extreme th ...

David Taylor Model Basin
The David Taylor Model Basin (DTMB) is one of the largest ship model basins—test facilities for the development of ship design—in the world. DTMB is a field activity of the Carderock Division of the Naval Surface Warfare Center. History In 1896, David Watson Taylor designed and supervised construction of the Washington Navy Yard's Experimental Model Basin which was at that time the best facility in the world. That facility was a significant design testing capability before, during, and after World War I. Inadequacies in that facility led the navy to look for a new model capability. The new navy modeling facility – named for David Taylor – was built in 1939 in today's community of Carderock just west of Bethesda, Maryland in Montgomery County. The Carderock facility contains multiple test basins (towing tanks for models) designed for a variety of testing capabilities. DTMB has strongly influenced naval architecture for 70 years. Technical capabilitie ...
