Plain Of The Cul-de-Sac
Plain of the Cul-de-Sac (french: Plaine du Cul-de-Sac, also known as the Cul-de-Sac Plain, or the Cul-de-Sac Depression) is a fertile lowland on the island of Hispaniola. It extends from southeastern Haiti into the southwestern Dominican Republic, where it is known as the ''Hoya de Enriquillo''. Geography Covering an area of 28 000 km² around with a length of 32 km long and 25 km wide, the Plain of the Cul-de-Sac is bounded to the north and south by high mountains and to the west by the Gulf of Gonâve on edges of which is the Haitian capital of Port-au-Prince and to the Plaine de l'Arcahaie that extends to the west. The Plain of the Cul-de-Sac extends eastward into the Dominican Republic. This valley was once an arm of the sea and upon withdrawal of the latter during the uprising Oligocene Miocene, salt water was trapped in the lowest points of depression resulting in two grand lakes; the Etang Saumâtre (also called "Lake Azuéi") in Haiti and Lake Enriquillo i ...

Lowland
Upland and lowland are conditional descriptions of a plain based on elevation above sea level. In studies of the ecology of freshwater rivers, habitats are classified as upland or lowland. Definitions Upland and lowland are portions of plain that are conditionally categorized by their elevation above the sea level. Lowlands are usually no higher than , while uplands are somewhere around to . On unusual occasions, certain lowlands such as the Caspian Depression lie below sea level. Upland habitats are cold, clear and rocky whose rivers are fast-flowing in mountainous areas; lowland habitats are warm with slow-flowing rivers found in relatively flat lowland areas, with water that is frequently colored by sediment and organic matter. These classifications overlap with the geological definitions of "upland" and "lowland". In geology an "upland" is generally considered to be land that is at a higher elevation than the alluvial plain or stream terrace, which are considered ...

Trou Caïman
Trou Caïman (literally " Caiman's Hole" in French), sometimes called Eau Gallée by locals, is a saltwater lake in Haiti known for its excellent birdwatching opportunities. Description The lake is 9 km (5.6 mi) long, 3 km (1.9 mi) wide, and approximately 16 km² (6.2 mi²) in area. It is located northeast of Croix-des-Bouquets in the Ouest department in the Plaine du Cul-de-Sac rift valley nearby much larger saline lakes, chiefly Lake Azuéi in Haiti east of which is Lake Enriquillo in the Dominican Republic. The predominant headwater of the lake is at low level east within the neater suburbs of Port-au-Prince, the country's capital. The lake is semi-endorheic An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes ... as seasonally it overflows into a str ...

Landforms Of Haiti
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canal Boucanbrou
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.

Rivière Blanche (Ouest)
Rivière Blanche is a river in Haiti in the Ouest department. Downstream, one arm is channeled towards the Étang Saumâtre, another joined the Canal Boucanbrou and the Trou Caïman. Geography Rivière Blanche has its source around the Pic la Selle, which rises to 2,680 meters above sea level, overlooking the mountains of peak. This river forms several arms when it arrives in the Plain of the Cul-de-Sac. In the past, the Rivière Blanche flowed into lakes whose arms are channeled either to the northeast of the Étang Saumâtre, or to the northwest of the Trou Caïman. The former name for this was called the ''Rivière du Boucan Brou'', however today, these arms are channeled under the name Boucanbrou or the Canal Boucambrou. During the rainy season, the Rivière Blanche becomes impetuous and overflows its banks, especially because the Canal Boucanbrou is not curetted and clear of the mud that reduces the flow of water. It floods partly in the Plaine of the Cul-de-Sac in the east ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Indigofera Tinctoria
''Indigofera tinctoria'', also called true indigo, is a species of plant from the bean family that was one of the original sources of indigo dye. Description True indigo is a shrub one to two meters high. It may be an annual plant, annual, biennial plant, biennial, or perennial, depending on the climate in which it is grown. It has light green pinnate leaves and sheafs of pink or violet flowers. The rotenoids deguelin, dehydrodeguelin, rotenol, rotenone, tephrosin and sumatrol can be found in ''I. tinctoria''. Distribution and habitat It has been naturalized to tropical and temperate Asia, as well as parts of Africa, but its native habitat is unknown since it has been in cultivation worldwide for many centuries. Agricultural use The plant is a legume, so it is rotated into fields to improve the soil in the same way that other legume crops such as alfalfa and beans are. The plant is also widely grown as a soil-improving groundcover. Dye Dye is obtained from the proces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Enriquillo
Lake Enriquillo ( es, Lago Enriquillo) is a hypersaline lake in the Dominican Republic located in the southwestern region of the country. Its waters are shared between the provinces of Bahoruco and Independencia, the latter of which borders Haiti. Lake Enriquillo is the largest lake in both the Dominican Republic and Hispaniola, as well as the entire Caribbean. It is also the lowest point for an island country. Hydrology Lake Enriquillo covers an area of 145 mi2 (375 km2), and is the lowest point for an island country, falling below sea level. Its drainage basin includes 10 minor river systems. The rivers that rise in the Neiba Mountains to the north (lower center and lower right of the image) are perennial. Those rivers that rise in the Baoruco Mountains to the south are intermittent. Lake Enriquillo has no outlet. The lake's water level varies because of a combination of storm-driven precipitation events and the region's high evaporation rate. Salinity in the lake ...

Hispaniola
Hispaniola (, also ; es, La Española; Latin and french: Hispaniola; ht, Ispayola; tnq, Ayiti or Quisqueya) is an island in the Caribbean that is part of the Greater Antilles. Hispaniola is the most populous island in the West Indies, and the region's second largest in area, after the island of Cuba. The island is divided into two separate nations: the Spanish-speaking Dominican Republic (48,445 km2, 18,705 sq mi) to the east and the French/ Haitian Creole-speaking Haiti (27,750 km2, 10,710 sq mi) to the west. The only other divided island in the Caribbean is Saint Martin, which is shared between France ( Saint Martin) and the Netherlands (Sint Maarten). Hispaniola is the site of one of the first European settlements in the Americas, La Navidad (1492–1493), as well as the first proper town, La Isabela (1493–1500), and the first permanent settlement, the current capital of the Dominican Republic, Santo Domingo (est. 1498). These settlements were founded succe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.
