Prado Dam
Prado Dam is an Embankment dam, earth-fill dry dam across the Santa Ana River at the Chino Hills near Corona, California in Riverside County, California, Riverside County with the resulting impounded water creating Prado Flood Control Basin reservoir. The U.S. Army Corps of Engineers built the dam in Lower Santa Ana River Canyon. Its primary purpose is flood control and it is the downstream element of the Santa Ana River's flood control system, which is a natural constriction about upstream from the ocean. The area upstream from the dam contains of the drainage basin, watershed's . The dam's construction was authorized in 1936 and the flood of 1938 demonstrated its necessity. Construction was completed in 1941. Prado Flood Control Basin also provides water storage for groundwater recharge operations. Failure threat On January 14, 2005, after days of heavy rain, water began seeping through an earthen extension. Authorities released water in order to relieve pressure and sent a fl ...

Santa Ana River
The Santa Ana River is the largest river entirely within Southern California in the United States. It rises in the San Bernardino Mountains and flows for most of its length through San Bernardino County, California, San Bernardino and Riverside County, California, Riverside counties, before cutting through the northern Santa Ana Mountains via Santa Ana Canyon and flowing southwest through urban Orange County, California, Orange County to drain into the Pacific Ocean. The Santa Ana River is long,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 16, 2011 and its drainage basin is in size. The Santa Ana drainage basin has a diversity of terrain, ranging from high peaks of inland mountains in the north and east, to the hot, dry interior and semidesert basins of the Inland Empire, to the flat coastal plain of Orange County. Although it includes areas of alpine climate, alpine and highland forest, the majority of the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Failure Threat
Failure is the social concept of not meeting a desirable or intended objective, and is usually viewed as the opposite of success. The criteria for failure depends on context, and may be relative to a particular observer or belief system. One person might consider a failure what another person considers a success, particularly in cases of direct competition or a zero-sum game. Similarly, the degree of success or failure in a situation may be differently viewed by distinct observers or participants, such that a situation that one considers to be a failure, another might consider to be a success, a qualified success or a neutral situation. It may also be difficult or impossible to ascertain whether a situation meets criteria for failure or success due to ambiguous or ill-defined definition of those criteria. Finding useful and effective criteria or heuristics to judge the success or failure of a situation may itself be a significant task. Sociology Cultural historian Scott San ...

Groundwater Recharge
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and/or reclaimed water is routed to the subsurface. The most common methods to estimate recharge rates are: chloride mass balance (CMB); soil physics methods; environmental and isotopic tracers; groundwater-level fluctuation methods; water balance (WB) methods (including groundwater models (GMs)); and the estimation of baseflow (BF) to rivers.

Buildings And Structures In Riverside County, California
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, 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 separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building practi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historic American Engineering Record In California
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to develop a ...

Historic American Engineering Record
Heritage Documentation Programs (HDP) is a division of the U.S. National Park Service (NPS). It administers three programs established to document historic places in the United States: Historic American Buildings Survey (HABS), Historic American Engineering Record (HAER), and Historic American Landscapes Survey (HALS). Its records include measured drawings, archival photographs, and written reports, all archived in the Library of Congress' Prints and Photographs Division. History Historic American Buildings Survey In 1933, the Historic American Buildings Survey was established following a proposal by Charles E. Peterson, a young landscape architect in the National Park Service. Peterson proposed that the survey would be "Almost a complete resume of the builder's art." Though it was founded as a temporary, "ten-weeks" constructive make-work program for architects, draftsmen, and photographers left jobless by the Great Depression, the Historic American Buildings Survey has endure ...

List Of Largest Reservoirs Of California
This is a list of the largest reservoirs, or man-made lakes, in the U.S. state of California. All fifty-three reservoirs that contain over of water at maximum capacity are listed. This includes those formed by raising the level of natural lakes, such as at Lake Tahoe. Most large reservoirs in California are owned by the federal Bureau of Reclamation and to a lesser extent the Army Corps of Engineers, many serving the Central Valley Project or State Water Project. Smaller ones are often run by county water agencies or irrigation and flood control districts. The state has more than one thousand major reservoirs, of which the largest two hundred have a combined capacity of over . Most large reservoirs in California are located in the central and northern portions of the state, especially along the large and flood-prone rivers of the Central Valley. Eleven reservoirs have a storage capacity greater than or equal to ; all of these except one are in or on drainages that feed into th ...
