Samalá River
The Samalá is a river in southwestern Guatemala. Its sources are in the Sierra Madre de Chiapas, Sierra Madre, San Carlos Sija, Valle De Écija range, in the departments of Quetzaltenango (department), Quetzaltenango and Totonicapán (department), Totonicapán. From there it flows down, past the towns San Carlos Sija in the San Carlos Sija, Valle De Écija, Quetzaltenango, San Cristóbal Totonicapán, Quetzaltenango, El Palmar, Quetzaltenango, El Palmar and Zunil, through the coastal plains of Retalhuleu (department), Retalhuleu into the Pacific Ocean. The Samalá river basin covers a territory of and has a population of around 400,000 people. Its proximity to the active Santamaria (volcano), Santa Maria and Santiaguito volcano complex, with its recurring lava and lahars flows, leads to a heightened risk of serious flooding.

Quetzaltenango (department)
Quetzaltenango is a department in the western highlands of Guatemala. The capital is the city of Quetzaltenango, the second largest city in Guatemala.Rouanet et al 1992, p.14. The department is divided up into 24 municipalities. The inhabitants include Spanish-speaking Ladinos and the K'iche' and Mam Maya groups, both with their own Maya language. The department consists of mountainous terrain, with its principal river being the Samalá River. the department is seismically active, suffering from both earthquakes and volcanic activity. Prior to the Spanish conquest the territory included in the modern department formed a part of the K'iche' Kingdom of Q'umarkaj. The kingdom was defeated by the Spanish under Pedro de Alvarado in a number of decisive battles fought near the city of Quetzaltenango, then known as Xelaju. In the 19th century the territory of the modern department was included in the short-lived Central American state of Los Altos. The department was created by decree ...

Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

Power Plant
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built by Wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escuintla
Escuintla () is an industrial city in Guatemala, its land extension is 4384 km², and it is nationally known for its sugar agribusiness. Its capital is a minicipality with the same name. Citizens celebrate from December 6 to 9 with a small fair in honor to The Immaculate Conception. In 2002 the city had a population of 86,678. It is located on the border of the central highlands and the Pacific coastal plain. Etymology Many of the names of the municipalities of Guatemala consist of one of two things: the name of a catholic saint to worship the day the city was founded or a description with Náhuatl roots. These influences are due to the troops in command of Pedro de Alvarado who invaded the region in 1520. These troops were composed of Spanish soldiers and indigenous Tlaxcaltecs. The name Escuintla, comes from the indigenous language nahuatl «Itzcuintlán», which is a word composed of two words: · «Itzcuintli»: means “dog” · «tlan»: means “abunda ...

Guatemala
Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America. It is bordered to the north and west by Mexico; to the northeast by Belize and the Caribbean; to the east by Honduras; to the southeast by El Salvador and to the south by the Pacific Ocean. With an estimated population of around million, Guatemala is the most populous country in Central America and the 11th most populous country in the Americas. It is a representative democracy with its capital and largest city being Nueva Guatemala de la Asunción, also known as Guatemala City, the most populous city in Central America. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica. In the 16th century, most of this area was conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence in 1821 from Spain and Mexico. In 1823, it became part of the Fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to ...

Hydroelectric Power Stations In Guatemala
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.
