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 ...

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 earth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guyana
Guyana ( or ), officially the Cooperative Republic of Guyana, is a country on the northern mainland of South America. Guyana is an indigenous word which means "Land of Many Waters". The capital city is Georgetown. Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Venezuela to the west, and Suriname to the east. With , Guyana is the third-smallest sovereign state by area in mainland South America after Uruguay and Suriname, and is the second-least populous sovereign state in South America after Suriname; it is also one of the least densely populated countries on Earth. It has a wide variety of natural habitats and very high biodiversity. The region known as "the Guianas" consists of the large shield landmass north of the Amazon River and east of the Orinoco River known as the "land of many waters". Nine indigenous tribes reside in Guyana: the Wai Wai, Macushi, Patamona, Lokono, Kalina, Wapishana, Pemon, Akawaio and Warao. Histo ...

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 Intertr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demerara
Demerara ( nl, Demerary, ) 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 in 1812 by the British who took control. It formally became a British colony in 1815 till Demerara-Essequibo was merged with Berbice to form the colony of British Guiana in 1831. In 1838, it became a county of British Guiana till 1958. In 1966, British Guiana gained independence as 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. The name "Demerara" comes from a variant of the Arawak word "Immenary" or "Dumaruni", which means "river of the letter wood" (wood of ''Brosimum guianense'' tree). Demerara sugar is so named because originally, it came from sugarcan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geotextile
Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in two basic forms: woven (resembling mail bag sacking) and nonwoven (resembling 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 and environmental engineering design. History Geotextiles were originally intended to be a substitute for granular soil filters. The original, and still sometimes used, term for geotextiles is ''filter fabrics''. Work originally began in the 1950s with R.J. Barrett using geotextiles behind precast concrete seawalls, under precast c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

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 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 households. Percenta ...

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 cultivation of crops, 2% 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 dikes and dams which were built by the Dutch using slave labor. 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 the primary industry, at around 15% of the total a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
