Hope Canal
The East Demerara Water Conservancy-Northern Relief Channel, better known locally as the Hope Canal, is one of Guyana's largest drainage projects. Construction was from 2011 to November 9, 2013, at a cost of around GYD$3.6 billion. Hope Canal was designed in response to the 2005 flooding, when a breach in the embankment resulted in floods to almost the entire East Coast of Demerara causing significant damage to agricultural and residential areas. It serves as a medium to release excess water from the EDWC directly to the Atlantic Ocean via an 8-door sluice, during periods of extended rainfall in order to prevent overtopping of conservancy embankment. The project was criticized for costing well over estimates and two years of delays. Structures There are four major components of the Hope Canal Project: Canal The channel has a length of 10.3 km and entirely straight with a bed width of 30m and a top width of 40m. The embankments are at least 8m higher than the surrounding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Demerara Water Conservancy
The East Demerara Water Conservancy (EDWC) is one of Guyana's major water storage and flood control facilities. Over 500,000 residents inhabit the basin that lies below and between the sea wall and the EDWC Dam in a 48 km band from Georgetown to Mahaica. Located in Demerara-Mahaica, the EDWC serves to irrigate thousands of hectares of rice and other crops within this area by storing rain water for dry periods and it also provides one of the primary source (about 60%) of drinking water for the capital city of Georgetown. The irrigation network also has a number of drainage relief structures to protect the EDWC Dam from over-topping and collapse during the rainy periods including the Hope Canal, which connects the EDWC to the Atlantic Ocean. The Guyana Sugar Corporation is completely reliant on water from the EDWC. Location The EDWC is located 15 miles south of the most densely populated section of the Guyana Coast. It is bounded to the North by a man-made 45 mile earthen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guyana
Guyana, officially the Co-operative Republic of Guyana, is a country on the northern coast of South America, part of the historic British West Indies. entry "Guyana" Georgetown, Guyana, Georgetown is the capital of Guyana and is also the country's largest city.

2005 Georgetown Flood
The 2005 Georgetown flood (also referred to as the Great Flood) was a major flood in and around Georgetown, the capital of Guyana. It started during heavy rains in 2004, and came to a head in January, when sustained heavy rains and high tides over-topped the deteriorating water conservancy. Approximately 290,000 people (39% of Guyana's population) were affected and the economic impact was estimated to be about US$465 million, or 59% of Guyana's GDP. Background Guyana's population resides mostly along the Atlantic coast, in a coastal strip below mean sea level. The population centers along the coast is locked between the Atlantic Ocean (north) and a series of storage reservoirs (conservancies) to the south. Flood waters are drained via a complex drainage system either by pumping, or at low tide; when the sea level is low enough to allow for gravity-based release through a number of sluices. Guyana has two rainfall seasons, triggered by the north–south movement of the Intertro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demerara
Demerara (; , ) is a historical region in the Guianas, on the north coast of South America, now part of the country of Guyana. It was a colony of the Dutch West India Company between 1745 and 1792 and a colony of the Dutch state from 1792 until 1815. It was merged with Essequibo (colony), Essequibo in 1812 by the British who took control. It formally became a British colony in 1815 until Demerara-Essequibo was merged with Berbice to form the colony of British Guiana in 1831. In 1838, it became a county of British Guiana until 1958. In 1966, British Guiana gained independence as Guyana (1966–1970), Guyana and in 1970 it became a republic as the Co-operative Republic of Guyana. It was located around the lower course of the Demerara River, and its main settlement was Georgetown, Guyana, Georgetown. The name "Demerara" comes from a variant of the Arawak word or , which means "river of the :wikt:letterwood, letter wood" (wood of ''Brosimum guianense'' tree). Demerara sugar is so ...

Geotextile
Geotextiles are versatile permeable fabrics that, when used in conjunction with soil, can effectively perform multiple functions, including separation, filtration, reinforcement, protection, and drainage. Typically crafted from polypropylene or polyester, geotextile fabrics are available in two primary forms: woven, which resembles traditional mail bag sacking, and nonwoven, which resembles felt. Geotextile composites have been introduced and products such as geogrids and meshes have been developed. Geotextiles are durable and are able to soften a fall. Overall, these materials are referred to as geosynthetics and each configuration—geonets, geosynthetic clay liners, geogrids, geotextile tubes, and others—can yield benefits in geotechnical engineering, geotechnical and environmental engineering design. History Geotextiles were originally intended to be a substitute for granular soil filters. Geotextiles can also be referred to as ''filter fabrics''. In the 1950s, R.J. Barr ...

Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...

Water Supply And Sanitation In Guyana
Guyana, meaning "land of many waters", is rich in water resources. Most of the population is concentrated in the coastal plain, much of which is below sea level and is protected by a series of sea walls. A series of shallow reservoirs inland of the coastal plain, called "water conservancies", store surface water primarily for irrigation needs.US Army Corps of EngineersWater Resources Assessment of Guyana, 1998/ref> Key issues in the Water supply, water and sanitation sector in Guyana are poor service quality, a low level of cost recovery and low levels of access. Access Overview The Joint Monitoring Program (JMP) for water and sanitation of WHO/UNICEF data defines a basic water source as "Drinking water from an improved source, provided collection time is not more than 30 minutes for a round trip including queuing". JMP figures define basic sanitation as facilities that are designed to hygienically separate excreta from human contact and are not shared among other househo ...

Agriculture In Guyana
Agriculture in Guyana is dominated by sugar and rice production. Although once the chief industry, it has been overshadowed by mining. Land use Historically, agriculture was the chief economic activity in Guyana despite the coastal plain which comprised only about 5 percent of the country's land area being suitable for Horticulture, cultivation of crops, 2% Arable land, arable land. Much of this fertile area lay more than one meter below the high-tide level of the sea and had to be protected by a system of Dike (construction), dikes and dams which were built by the Dutch using slave labour. In the 1980s, there were reports that the 200-year-old system of dikes in Guyana was in a serious state of disrepair. Production Sugar and rice are the most important primary agricultural products, as they had been since the nineteenth century. Sugar was produced primarily for export whereas most rice was consumed domestically. Today in Guyana sugar production generates the most revenue in th ...
