Kokee Ditch
The Kōkee Ditch is an irrigation canal on the island of Kauai. In 1923, construction began on the Kōkee Ditch system to open the mauka hills to sugar cane production. By 1926, the Kōkee Ditch was completed, diverting water from Mohihi Stream and the headwaters of the Waimea River in the Alakai Swamp at an altitude of about 3400 feet. About one-fourth of the Kōkee Ditch supply irrigated the highland sugar cane fields below Puu Ōpae reservoir A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam.

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow Crop, crops, Landscape plant, landscape plants, and Lawn, lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irri ...

Canal
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many ...

Kauai
Kauai, () anglicized as Kauai ( ), is geologically the second-oldest of the main Hawaiian Islands (after Niʻihau). With an area of 562.3 square miles (1,456.4 km2), it is the fourth-largest of these islands and the 21st largest island in the United States. Nicknamed the Garden Isle, Kauai lies 73 miles (117 km) across the Kauai Channel, northwest of Oahu. This island is the site of Waimea Canyon State Park and the Na Pali Coast State Park. The United States Census Bureau defines Kauai as census tracts 401 through 409 of Kauai County, Hawaii, which comprises all of the county except the islands of Kaʻula, Lehua and Niihau. The 2020 United States census population of the island was 73,298. The most populous town is Kapaa. Etymology and language Hawaiian narrative locates the name's origin in the legend of Hawaiiloa, the Polynesian navigator credited with discovery of the Hawaiian Islands.

Sugar Cane
Sugarcane or sugar cane is a species of (often hybrid) tall, perennial grass (in the genus ''Saccharum'', tribe Andropogoneae) that is used for sugar production. The plants are 2–6 m (6–20 ft) tall with stout, jointed, fibrous stalks that are rich in sucrose, which accumulates in the stalk internodes. Sugarcanes belong to the grass family, Poaceae, an economically important flowering plant family that includes maize, wheat, rice, and sorghum, and many forage crops. It is native to the warm temperate and tropical regions of India, Southeast Asia, and New Guinea. The plant is also grown for biofuel production, especially in Brazil, as the canes can be used directly to produce ethyl alcohol (ethanol). Grown in tropical and subtropical regions, sugarcane is the world's largest crop by production quantity, totaling 1.9 billion tonnes in 2020, with Brazil accounting for 40% of the world total. Sugarcane accounts for 79% of sugar produced globally (most of the rest is ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waimea River (Kauai)
The Waimea River is the largest and the longest river on the island of Kauai in the U.S. state of Hawaii. At in length,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed April 28, 2011 it is the 3rd longest rivers in the Hawaiian Islands, draining one sixth of the total area of the island. It rises in a wet plateau of the island's central highlands, in the Alaka'i Swamp, the largest high-elevation swamp in the world. It flows south, passing through the spectacular Waimea Canyon, known as the " Grand Canyon of the Pacific." The valleys of the Waimea River and its tributary, the Makaweli River, were once heavily populated. It enters the Pacific Ocean at Waimea, near the 1778 landing place of Captain Cook James Cook (7 November 1728 Old Style date: 27 October – 14 February 1779) was a British explorer, navigator, cartographer, and captain in the British Royal Navy, famous for his three voyages between 1768 a ...

Alakai Wilderness Area
''HST-2'', formerly named USNS ''Puerto Rico'' and ''Alakai'', is a vessel owned by the United States Navy Military Sealift Command. She was originally Hawaii Superferry's first high-speed ferry. The vessel was later chartered by Bay Ferries Limited to operate a ferry service between Maine and Yarmouth, Nova Scotia. The design of the is similar to the two high-speed ferries operated by Hawaii Superferry, both built by Austal USA. Vessel ''HST-2'' was built as ''Alakai'', which means "sea path" in the Hawaiian language. The vessel is a long high-speed roll-on/roll-off (Ro/Ro) passenger and vehicle ferry. She used to operate a daily service operated by Hawaii Superferry at a speed of between the islands of Oahu and Maui. ''HST-2'' has a capacity of 866 passengers and up to 282 subcompact cars. Alternately, its vehicle decks can be reconfigured in five minutes to carry up to 20 large trucks and 90 cars. Like her sister ship (formerly ''Huakai''), the vessel features environm ...

Reservoir (water)
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...
