Department Of Water And Power
The Los Angeles Department of Water and Power (LADWP) is the largest municipal utility in the United States with 8,100 megawatts of electric generating capacity (2021-2022) and delivering an average of 435 million gallons of water per day to more than four million residents and local businesses in the City of Los Angeles. It was founded in 1902 to supply water to residents and businesses in the Los Angeles and surrounding communities. In 1917, it began to deliver electricity to portions of the city. It has been involved in a number of controversies and media portrayals over the years, including the 1928 St. Francis Dam failure and the books ''Water and Power'' and '' Cadillac Desert''. History Private operators By the middle of the 19th century, Los Angeles's rapid population growth magnified problems with the city's water distribution system. At that time, a system of open, often polluted ditches, was reasonably effective at supplying water for agricultural production bu ...

Ventura, California
Ventura, officially named San Buenaventura (Spanish for "Saint Bonaventure"), is a city on the Southern Coast of California and the county seat of Ventura County. The population was 110,763 at the 2020 census. Ventura is a popular tourist destination, owing to its historic landmarks, beaches, and resorts.

Following the American Conquest of California, San Buenaventura eventually incorporated as a city in 1866. The 1920s brought a major oil boom, which along with the post–World War II economic expansion, significantly developed and expanded Ventura.

Dam Break
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. Da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1994 Northridge Earthquake
The 1994 Northridge earthquake was a moment 6.7 (), blind thrust earthquake that occurred on January 17, 1994, at 4:30:55 a.m. PST in the San Fernando Valley region of the City of Los Angeles. The quake had a duration of approximately 10–20 seconds, and its peak ground acceleration of 1.82 ''g'' was the highest ever instrumentally recorded in an urban area in North America. Shaking was felt as far away as San Diego, Turlock, Las Vegas, Richfield, Phoenix and Ensenada. The peak ground velocity at the Rinaldi Receiving Station was , the fastest ever recorded. Two 6.0 aftershocks followed, the first about one minute after the initial event and the second approximately 11 hours later, the strongest of several thousand aftershocks in all. The death toll was 57, with more than 9,000 injured. In addition, property damage was estimated to be $13–50 billion (equivalent to $24–93 billion in 2021), making it one of the costliest natural disasters in U.S. history. Epi ...

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 ...

Los Angeles Aqueduct
The Los Angeles Aqueduct system, comprising the Los Angeles Aqueduct (Owens Valley aqueduct) and the Second Los Angeles Aqueduct, is a water conveyance system, built and operated by the Los Angeles Department of Water and Power. The Owens Valley aqueduct was designed and built by the city's water department, at the time named The Bureau of Los Angeles Aqueduct, under the supervision of the department's Chief Engineer William Mulholland. The system delivers water from the Owens River in the Eastern Sierra Nevada Mountains to Los Angeles, California. The aqueduct's construction was controversial from the start, as water diversions to Los Angeles eliminated the Owens Valley as a viable farming community. Clauses in the city's charter originally stated that the city could not sell or provide surplus water to any area outside the city, forcing adjacent communities to annex themselves into Los Angeles. The aqueduct's infrastructure also included the completion of the St. Francis Dam i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Francisquito Canyon
San Francisquito Canyon is a canyon created through erosion of the Sierra Pelona Mountains by the San Francisquito Creek, in Los Angeles County, Southern California. Geography The canyon cuts through the Sierra Pelona Mountains, which are central part of the Transverse Ranges system of California. At the San Francisquito Canyon head is the San Francisquito Pass, which the early routes between Los Angeles and the San Joaquin Valley crossed. The canyon grows wider as it approaches the Santa Clarita Valley. The middle and upper portions of this canyon fall within the Angeles National Forest. History Mining San Francisquito Canyon was the site of placer mining for gold by Spanish missionaries from the San Fernando and San Buenaventura Missions, and later by Mexican Californios. Their activity stopped in 1848, when the gold discovery at Sutter's Mill started the California Gold Rush. Placer mining later occurred in the canyon into at least the late 19th century.

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.
