Tujunga Wash
Tujunga Wash is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 16, 2011 stream in Los Angeles County, California. It is a tributary of the Los Angeles River, providing about a fifth of its flow, and drains about . It is called a wash because it is usually dry, especially the lower reaches, only carrying significant flows during and after storms, which usually only occur between November and April. The name of the wash derives from a Tongva village name. About The name ''Tujunga'' or ''Tuxunga'' means "old woman's place" in both Fernandeño and Tongva, where ''Tuxu'' means "old woman". The term is thought to relate to an ethnohistoric narrative, known as Khra'wiyawi, collected by Carobeth Laird from Juan and Juana Menendez at the Leonis Adobe in 1916. In the narrative, the wife of Khra'wiyawi (the chief of the region) is stricken with grief over the untimely loss of her daughter. In her sadness, she retreats to the ...

Coast Line (UP)
The Coast Line is a railroad line between Burbank, California and the San Francisco Bay Area, roughly along the Pacific Coast. It is the shortest rail route between Los Angeles and the Bay Area. History Predecessors The San Francisco and San Jose Railroad built the first segment of the line from San Francisco to San Jose between 1860 and 1864. The founders of the SF&SJ incorporated as the Southern Pacific Railroad, which was authorized by Congress in 1866 to connect the line from San Jose south to Needles, where it would meet the Atlantic & Pacific Railroad. However, SP had built to Tres Pinos by 1873 and abandoned efforts to continue the line to Coalinga, instead choosing a route from Lathrop. By 1871, SP had completed a line south from San Jose through Gilroy and Pajaro, arriving at Salinas in 1872 and Soledad in 1873. SP halted southward work at Soledad for thirteen years and started building north from Los Angeles in 1873, completing a line to Burbank. In 1886, SP ha ...

Union Pacific
The Union Pacific Railroad , legally Union Pacific Railroad Company and often called simply Union Pacific, is a freight-hauling railroad that operates 8,300 locomotives over routes in 23 U.S. states west of Chicago and New Orleans. Union Pacific is the second largest railroad in the United States after BNSF, with which it shares a duopoly on transcontinental freight rail lines in the Western, Midwestern and Southern United States. Founded in 1862, the original Union Pacific Rail Road was part of the first transcontinental railroad project, later known as the Overland Route. Over the next century, UP absorbed the Missouri Pacific Railroad, the Chicago and North Western Transportation Company, the Western Pacific Railroad, the Missouri–Kansas–Texas Railroad and the Chicago, Rock Island and Pacific Railroad. In 1996, the Union Pacific merged with Southern Pacific Transportation Company, itself a giant system that was absorbed by the Denver and Rio Grande Western Railroad. ...

California State Route 170
Year 170 ( CLXX) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Clarus and Cornelius (or, less frequently, year 923 ''Ab urbe condita''). The denomination 170 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * The Suebian tribes of the Marcomanni cross the Danube and invade Northern Italy.

Interstate 5 In California
Interstate 5 (I-5) is a major north–south route of the Interstate Highway System in the United States, stretching from the Mexican border at the San Ysidro crossing to the Canadian border near Blaine, Washington. The segment of I-5 in California runs across the length of the state from San Ysidro to the Oregon state line south of the Medford- Ashland metropolitan area. It is the longest interstate in California, and accounts for more than half of I-5's total length. It is the more important and most-used of the two major north–south routes on the Pacific Coast, the other being U.S. Route 101 (US 101), which is primarily coastal. I-5 links the major California cities of San Diego, Santa Ana, Los Angeles, Stockton, Sacramento, and Redding. The San Francisco Bay Area is about west of the highway. I-5 is known colloquially as "the 5" to Southern California residents and "5" to Northern California residents due to varieties in California English. I-5 als ...

Laurel Canyon Boulevard
Laurel Canyon Boulevard is a major street in the city of Los Angeles. It starts off at Polk Street in Sylmar in the northern San Fernando Valley near the junction of the San Diego ( Interstate 405) and the Golden State (I-5)) freeways. Laurel Canyon Boulevard bypasses the city of San Fernando to the west, running parallel to I-5 in the vicinity of Pacoima and Arleta. The portion through Sun Valley passes through rock quarries and a great deal of open space. From the intersection with Webb Avenue, Laurel Canyon Boulevard heads due south, cutting through North Hollywood, closely following the Hollywood Freeway ( SR 170). Laurel Canyon Boulevard passes through the Valley Village neighborhood, one mile (1.6 km) west of the Hollywood Split (the intersection of the Hollywood (U.S. 101/ SR 170) and Ventura (U.S. 101/ SR 134) freeways). This would have been the start of the proposed Laurel Canyon Freeway, which would have provided a direct freeway connection from the southeastern ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Processes Water is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). Recharge may be impeded somewhat by human activities including paving, development, or logging. These activities can result in loss of topsoil resulting in reduced water infiltration, enhanced surface runoff and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Control
Flood control methods are used to reduce or prevent the detrimental effects of flood waters."Flood Control", MSN Encarta, 2008 (see below: Further reading). Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Though building hard infrastructure to prevent flooding, such as flood walls, can be effective at managing flooding, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. For flooding on coasts, coastal management practices have to not only handle changes water flow, but also natural processes like tides. Flood control and relief is a particularly important part of climate change adaptation and climate resilience, both sea level rise and changes in the weather (climate cha ...
