Carraízo Dam
Carraízo Dam is a concrete gravity dam located in the municipality of Trujillo Alto, Puerto Rico within the flow of the Río Grande de Loíza. Its construction was completed in 1953. Carraízo Dam impounds Loíza Lake which serves as Puerto Rico's main water reservoir. Background and construction At the end of the 1940s, the Puerto Rico Aqueducts and Sewers Authority (PRASA) proposed the construction of a dam at the Río Grande de Loíza in the Barrio Carraízo of Trujillo Alto with the intention of providing both water and electricity to the San Juan Metropolitan Area. Construction of the dam began in 1950 and finished in 1954. As part of the construction, the dam included three hydroelectric turbines with a total capacity of 3 Megawatts for the provision of electricity. However, during the 1960s and 1970s, the turbines were shut down because their operation and maintenance wasn't considered cost-effective versus the cost of buying energy at the time. In 1989 Hurricane Hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Río Grande De Loíza
The Rio Grande de Loíza (English: ''Great River of Loíza'', ''Grande de Loíza'', or just ''Loíza River'') is a river in the island of Puerto Rico. It is the largest river in Puerto Rico by discharge volume. It is situated on the north coast of the island. It flows from south to north and drains into the Atlantic Ocean, a few miles east of San Juan. ''Rio Grande de Loíza'' runs for approximately . It has its origin in the municipality of San Lorenzo at an altitude of approximately above sea level. It runs through the municipalities of San Lorenzo, Caguas, Gurabo, Trujillo Alto, Carolina, Canóvanas and Loíza, forming the Loíza Lake along its route, making it the second longest river on the island, behind Río de la Plata. Geography The Rio Grande de Loíza basin is the largest in Puerto Rico with an area of 289.9 square miles. The source of the river is located in the Espino barrio of San Lorenzo, Puerto Rico on the eastern slopes of the Sierra de Cayey mountain ran ...

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

Dams In Puerto Rico
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Floodgate
Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or storm surge system. Since most of these devices operate by controlling the water surface elevation being stored or routed, they are also known as crest gates. In the case of flood bypass systems, floodgates sometimes are also used to lower the water levels in a main river or canal channels by allowing more water to flow into a flood bypass or detention basin when the main river or canal is approaching a flood stage. Types Valves Valves used in floodgate applications have a variety of design requirements and are usually located at the base of dams. Often, the most important requirement (besides regulating flow) is energy dissipation. Since water is very he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FEMA - PR DR4339 1405 - Community Flooded
The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security (DHS), initially created under President Jimmy Carter by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive order (United States), Executive Orders on April 1, 1979. The agency's primary purpose is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and U.S. state, state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the President of the United States, President that FEMA and the Federal government of the United States, federal government respond to the disaster. The only exception to the state's gubernatorial declaration requirement occurs when an emergency or disaster takes place on federal property or to a federal asset—for example, the 1995 Oklahoma City bombing, bombing of the Alfred ...

Hurricane Hugo
Hurricane Hugo was a powerful Cape Verde tropical cyclone that inflicted widespread damage across the northeastern Caribbean and the Southeastern United States in September 1989. Across its track, Hugo affected approximately 2 million people. Its direct effects killed 67 people and inflicted $11 billion (equivalent to $ billion in ) in damage. The damage wrought by the storm was more costly than any Atlantic hurricane preceding it. At its peak strength east of the Lesser Antilles, Hugo was classified as a Category 5 hurricane—the highest rating on the Saffir–Simpson scale. Over the course of five days, Hugo made landfalls on Guadeloupe, Saint Croix, Puerto Rico, and South Carolina, bringing major hurricane conditions to these and surrounding areas. Lesser effects were felt along the periphery of the hurricane's path in the Lesser Antilles and across the Eastern United States into Eastern Canada. The scale of Hugo's impacts led to the retirement of the name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, 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 energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, 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.
