Tampa Bypass Canal The Tampa Bypass Canal and Palm River are a 14 mi flood bypass operated by the Southwest Florida Water Management District. The canal includes several concrete flood control structures and was constructed during the 1960s and 1970s. Its purpose is to redirect flood waters from large amounts of rainfall from the Hillsborough River to Tampa Bay to prevent floodwaters reaching homes and businesses. Despite its original purpose it is now used as a drinking water source for the City of Tampa. During construction of the canal the Floridan aquifer was accidentally breached.

Containment dome A containment dome is a component of the system designed to contain the underwater blowout of an oil well such as occurred with the Macondo Well blowout from the Deepwater Horizon oil spill. This portion of the system is designed as a vacuum to suck up the products being expelled from a blowout and deliver those products to the containment system housed on the vessel moored above the blowout. Superior Energy Services is constructing this device to be used by Shell Oil Company on the barge "Arctic Challenger" as their "fourth line of defense" against a blowout in the Arctic drilling regions in the Chukchi Sea and Beaufort Sea.

Construction barrel Construction barrels (officially known as "drums" in the United States) are traffic control devices used to channel motor vehicle traffic through construction sites or to warn motorists of construction activity near the roadway. They are used primarily in the United States, but are occasionally used in Canada and Mexico. They are an alternative to traffic cones which are smaller and easily hit by vehicles. Drums tend to command more respect from drivers than cones as they are larger, more visible, and give the appearance of being formidable obstacles.

Valley of the Drums The Valley of the Drums is a 23-acre (9.3 hectare) toxic waste site in northern Bullitt County, Kentucky, near Louisville, named after the waste-containing drums strewn across the area. It is known as one of the primary motivations for the passage of the Comprehensive Environmental Response, Compensation, and Liability Act, or Superfund Act of 1980. While the widely publicized Love Canal disaster is often credited as the reason the Superfund law was passed, Love Canal activist Lois Gibbs has said that Love Canal looked like a suburban community, while "Valley of the Drums became the visualization of the problem."

Guayape River The Guayape River" ("Río Guayape in Spanish) is a major river that drains much of the Department of Olancho and central Honduras. The largest tributary to the Guayape is the Río Jalán, which joins it at El Plomo, not far from the town of Juticalpa. From there the river passes many small towns, including El Esquilinchuche. The largest bridge over the Guayape is the Puente del Burro, a modern cement structure that replaced the huge steel suspension bridge that had stood for decades after being built by the US Army Corps of Engineers, and was destroyed by Hurricane Mitch in 1998. Far downriver from the bridge, the Guayape joins with the Guayambre River, from then on the waterway is known as the Río Patuca.

Crevasse splay A crevasse splay is a sedimentary fluvial deposit which forms when a stream breaks its natural or artificial levees and deposits sediment on a floodplain. A breach that forms a crevasse splay deposits sediments in similar pattern to an alluvial fan deposit. Once the levee has been breached the water flows out of its channel. As the water spreads onto the flood plain sediments will start to fall out of suspension as the water loses energy. The resulting deposition can create graded deposits similar to those found in Bouma sequences. In some cases crevasse splays can cause a river to abandon its old river channel, a process known as avulsion. Breaches that form a crevasse splay deposits occur most commonly on the outside banks of meanders where the water has the highest energy. Crevasse splay deposits can range in size. Larger deposits can be 6 m thick at the levee and spread 2 km wide, while smaller deposits may only be 1 cm thick.

Alva B. Adams Tunnel The Alva B. Adams Tunnel is the principal component of the largest transmountain water project in Colorado, the Colorado-Big Thompson Project (C-BT). The tunnel transfers water from the western slope of the Colorado River drainage to the eastern Front Range of Colorado. The tunnel is 13.1 mi long and has a concrete lined diameter of 9.75 ft . The tunnel drops 109 ft in elevation along its length and runs in a straight line under the Continental Divide from west to east passing under Rocky Mountain National Park. At its deepest point, the tunnel is about 3,800 ft below the surface of the mountain peaks. Construction began on 15 June 1940, but was suspended as a result of World War II priorities, from the end of 1942 to August 1943. The tunnel was holed through on 31 March 1944, an event that was broadcast throughout the United States by NBC Radio. The tunnel was posthumously named for its chief advocate, US Senator Alva B. Adams.

Castillo de Bellver oil spill The MT "Castillo de Bellver" oil spill began on 6 August 1983, when the Spanish tanker caught fire off Saldanha Bay, approximately 70 miles northwest of Cape Town, South Africa. It was carrying 250,000 tonnes (300,000 cubic metres) of light crude oil, and was traveling through an environmentally sensitive area known for its seabird rookeries and important commercial fishing grounds. The burning vessel was abandoned and broke apart after drifting offshore. The stern capsized and sunk and the bow was sunk using explosives. A total of 145,000-170,000 tonnes (176,000-210,000 cubic metres) of oil entered the sea. Onshore impacts were considered negligible as the slick traveled seaward. The only visible impact was the oiling of 1,500 gannets that were on a nearby island.

Leaky condo crisis The leaky condo crisis, also known as the leaky condo syndrome and rotten condo crisis, is an ongoing construction, financial, and legal crisis in Canada. It primarily involves multi-unit condominium (or "strata") buildings damaged by rainwater infiltration in the Lower Mainland and Vancouver Island regions of coastal British Columbia (B.C.). In B.C. alone an estimated $4 billion in damage has occurred to over 900 buildings and 31,000 individual housing units built between the late 1980s and early 2000s, establishing it as the most extensive and most costly reconstruction of housing stock in Canadian history.

2005 levee failures in Greater New Orleans On August 29, 2005, there were over 50 failures of the levees and flood walls protecting New Orleans, Louisiana, and its suburbs following passage of Hurricane Katrina and landfall in Mississippi. The levee and flood wall failures caused flooding in 80% of New Orleans and all of St. Bernard Parish. Tens of billions of gallons of water spilled into vast areas of New Orleans, flooding over 100,000 homes and businesses. Responsibility for the design and construction of the levee system belongs to the United States Army Corps of Engineers; the responsibility of maintenance belongs to the local levee boards. The Corps hands components of the system over to the local levee boards upon completion. When Katrina struck in 2005, the project was between 60–90% complete. Four major investigations were conducted by civil engineers and other experts in an attempt to identify the underlying reasons for the failure of the federal flood protection system. All concur that the primary cause of the flooding was inadequate design and construction by the Corps of Engineers.

Panama Canal Zone The Panama Canal Zone (Spanish: "Zona del Canal de Panamá" ) was an unincorporated territory of the United States from 1903 to 1979, centered on the Panama Canal and surrounded by the Republic of Panama. The zone consisted of the canal and an area generally extending 5 mi on each side of the centerline, excluding Panama City and Colón, which otherwise would have been partly within the limits of the Zone. Its border spanned three of Panama's provinces. When reservoirs were created to assure a steady supply of water for the locks, those lakes were included within the Zone.

Camlock (electrical) A camlock is an interchangeable electrical connector often used in temporary electrical power production and distribution. The most common form is the "16" series, rated at 400 amperes with 105 °C terminations. Also in common use is the "15" series ("mini-cam"), rated at 150 amperes. A larger version is made denoted as the "17" series with ratings up to 760 A. A ball nose version and a longer nose standard version exist-the latter is the most common. Another version is the "Posi-lok" which has controlled interconnection sequencing to a panel and a shrouded connector body.The early version original connector was hot-vulcanized to the cable body;later versions use dimensional pressure to exclude foreign material from the connector pin area;the tail of the connector insulator body is trimmable to fit the cable outer diameter.
