Olmos Dam
Olmos Dam is a detention dam located in San Antonio, Texas."Dams and Reservoirs in Texas: Historical and Descriptive Information, December 31, 1966," Cleo LaFoy Dowell, Seth Darnaby Breeding, ''Texas Water Development Board'', 1967. p.36 It was built in the 1920s, following the disastrous September 1921 San Antonio floods. Work began on the dam on January 19, 1925, completed in 1926, and in 1929 a ''cut-off channel'', to allow excess water to bypass the Great Bend in downtown, was completed. Projects, which together have been providing flood control. In the 1970s, improvements were made by the City of San Antonio and the San Antonio River Authority. In March 1979, an improvement was made to strengthen and anchor the dam, as well as modifying gate operations, in order to provide an emergency spillway. There are six gates within the dam, two of which are open at all times to a height of . They are rotated once a week. Each gate is controlled via an actuator that is situated inside t ...

Detention Dam
A detention dam is a dam built to catch surface runoff and stream water flow to regulate the water flow in areas below the dam. Detention dams are commonly used to reduce the damage caused by flooding or to manage the flow rate through a channel. Detention dams can also be constructed to replenish groundwater and trap sediment. Detention dams are one of three classifications of dams: storage dams, diversion dams, and detention dams. Storage dams store water for extended times for irrigation, livestock, municipal water supply, recreation, and hydroelectric power generation. Diversion dams raise the water level to redirect the water to a designated location. The diverted water typically supplies irrigation systems or reservoirs. Purposes People build detention dams for purposes that include: flood control, Discharge (hydrology), flow rate restriction, subsurface water replenishment, and sediment trapping. Detention dams are common in flood prone areas for flood control. A detention dam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

September 1921 San Antonio Floods
In early September 1921, the remnants of a Category 1 hurricane brought damaging floods to areas of Mexico and the U.S. state of Texas, particularly in the San Antonio region. On September 4, a tropical cyclone developed in the southwestern Gulf of Mexico near the Bay of Campeche. Moving slowly in a general westward direction, the disturbance reached hurricane intensity on September 7 prior to making landfall south of Tampico, Mexico the following day. The storm weakened over land, and lost cyclonic characteristics later that day. However, a nearby high-pressure area forced the remnants of the system northward into Texas. Due to an orographic lifting effect, the remnants were able to produce torrential and record rainfall over the state. Precipitation peaked over Central Texas, where the highest rainfall amount measured was 40 in (1,016 mm) near Thrall, Texas; this was the fourth-highest tropical cyclone-related rainfall total in Texas since rec ...

San Antonio River Authority
In 1917, the voters of Texas, recognizing the necessity of developing and conserving the State's water resources and inspired by devastating floods of 1913 and 1914, passed a Constitutional amendment allowing the Legislature to create special purpose political subdivisions of the State to serve regional areas, generally coincidental with river basins and to be generally known as river authorities. The San Antonio River Authority (SARA), created in 1937, is one of many such active river authorities in the State of Texas. Its jurisdiction covers 3,658 square miles—all of Bexar, Wilson, Karnes and Goliad Counties. A 12-member Board of Directors governs SARA. Six directors are elected from Bexar County and two are elected from each of the three other counties with each elected member serving six years. Policies established by the Board are executed by the management organization under the direction of a General Manager appointed by the Board. SARA has the statutory authority to imp ...

Actuator
An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a "mover". An actuator requires a control device (controlled by control signal) and a source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic, or hydraulic fluid pressure, or even human power. Its main energy source may be an electric current, hydraulic pressure, or pneumatic pressure. The Control device is usually a valve. When it receives a control signal, an actuator responds by converting the source's energy into mechanical motion. In the ''electric'', ''hydraulic'', and ''pneumatic'' sense, it is a form of automation or automatic control. History The history of the pneumatic actuation system and the hydraulic actuation system dates to around the time of World War II (1938). It was first created by Xhiter Anckeleman who used his knowledge of engines and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Native Americans In The United States
Native Americans, also known as American Indians, First Americans, Indigenous Americans, and other terms, are the Indigenous peoples of the mainland United States ( Indigenous peoples of Hawaii, Alaska and territories of the United States are generally known by other terms). There are 574 federally recognized tribes living within the US, about half of which are associated with Indian reservations. As defined by the United States Census, "Native Americans" are Indigenous tribes that are originally from the contiguous United States, along with Alaska Natives. Indigenous peoples of the United States who are not listed as American Indian or Alaska Native include Native Hawaiians, Samoan Americans, and the Chamorro people. The US Census groups these peoples as " Native Hawaiian and other Pacific Islanders". European colonization of the Americas, which began in 1492, resulted in a precipitous decline in Native American population because of new diseases, wars, ethni ...

Buildings And Structures Completed In 1927
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
