El Cajón Dam (Mexico)
The El Cajón Dam is a hydroelectric dam on the Río Grande de Santiago in the Mexican state of Nayarit. Construction began in 2003 and was completed in June 2007. It cost US$800 million to build. It is long and is high. The reservoir holds approximately of water, and the generators are capable of producing of electricity. The dam is operated by the Comisión Federal de Electricidad, a state-owned Mexican electric company. Throughout the construction of the El Cajón Dam, the following is estimated: * Rock fill with concrete face dam * A cost of 800 million dollars * An economic benefit of 2 billion pesos (160 million dollars) * The creation of approximately 10,000 direct and indirect jobs * The improvement of access roads that will benefit up to 20,000 inhabitants belonging to 40 communities * An annual mean power generation of 1,228 GWh, approximately 1.5 times the annual consumption of Nayarit * An installed capacity of * An approximate annual savings of two million bar ...

Río Grande De Santiago
The Río Grande de Santiago, or Santiago River, is a river in western Mexico. It flows westwards from Lake Chapala via Ocotlán through the states of Jalisco and Nayarit to empty into the Pacific Ocean. It is one of the longest rivers in Mexico, measuring up long. Geography The river begins at Lake Chapala, running through Ocotlán and continuing roughly north-west through the Sierra Madre Occidental range, receiving the Verde, Juchipila, Bolaños, Huaynamota, Mololoa, and other tributaries. The Río Grande de Santiago then descends over 1700 meters as it heads towards the sea. Downstream from Lake Chapala, the river and its major tributaries have carved deep narrow canyons, or ''barrancas'', which can be 600 meters lower than the surrounding plateau. The lower elevation and year-round moisture in the canyon bottoms sustain forests, which include many coastal tropical species not found on the plateaus. The Barranca de Oblatos or Barranca de Huentitán is a scenic and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indirect Jobs
Investments into an industry or project can produce temporary and long-term employment. The resulting jobs are typically categorized as being one of three types. A direct job is employment created to fulfill the demand for a product or service. An indirect job is a job that exists to produce the goods and services needed by the workers with direct jobs. Indirect employment includes the things need direct on the job as well as jobs produced because of the worker's needs (e.g., uniforms). Employment created by the additional personal spending (e.g., eating at a restaurant) by both direct and indirect workers is classified as an induced job. Projects may produce temporary and long-term jobs. Construction and installation jobs may be temporary. Operations and maintenance jobs tend to be long term. Examples Efficiency of job production Investments in some projects or industries are more efficient at producing direct and indirect jobs. For example, investing US$1,000,000 in the ...

Dams On The Río Grande De Santiago
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoir A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of wa ...s created by dams not only suppress floods but also provide water for activities such as irrigation, drinking water, human consumption, Industrial water, 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 Dike (construction), dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
