Centinela Creek
Ballona Creek (pronunciation: “Bah-yo-nuh” or “Buy-yo-nah” ) is an channelized stream in southwestern Los Angeles County, California, United States, that was once a “year-round river lined with sycamores and willows.” Ballona Creek and neighboring Ballona Wetlands remain a prime bird-watching spot for waterfowl, shorebirds, warblers, and birds of prey. The urban watercourse begins in the Mid-City neighborhood of Los Angeles, flows through Culver City and Del Rey, and passes the Ballona Wetlands Ecological Preserve, the sailboat harbor Marina del Rey, and the small beachside community of Playa del Rey before draining into Santa Monica Bay. The Ballona Creek drainage basin carries water from the Santa Monica Mountains on the north, from the Baldwin Hills to the south, and as far as the Harbor Freeway (I-110) to the east. In 1982, film critic Richard von Busack, a native of Culver City, described his hometown as a “grim industrial suburb…bisected by Ballon ...

Baldwin Hills (mountain Range)
__NOTOC__ The Baldwin Hills are a low mountain range surrounded by and rising above the Los Angeles Basin plain in central Los Angeles County, California. The Pacific Ocean is to the west, the Santa Monica Mountains to the north, Downtown Los Angeles to the northeast, and the Palos Verdes Hills to the south - with all easily viewed from the Baldwin Hills. Geography The headwaters of the urban river known as Ballona Creek are in the Santa Monica Mountains, such as above Beverly Hills and flows along the north base of Baldwin Hills through an active geological watergap, on the way to the Pacific Ocean in Santa Monica Bay. La Cienega Boulevard goes through a pass in the ridge of the Baldwin Hills between Inglewood and Culver City, and northeast of Los Angeles International Airport. La Cienega Boulevard is a parkway road passing alongside open space of large private corporate lands with oil wells of the Inglewood Oil Field in the southern Baldwin Hills.

Stone Canyon Reservoir
Stone Canyon Reservoir and Upper Stone Canyon Reservoir are adjoining reservoirs in the Westside region of Los Angeles, California. Situated in the Santa Monica Mountains at above sea level, the reservoirs lie in the Bel Air neighborhood, south of Mulholland Drive and west of North Beverly Glen Boulevard. The main reservoir is the Stone Canyon Reservoir with the much smaller, cone-shaped Upper Stone Canyon Reservoir adjoining it to the north. The two reservoirs supply the Westside water subsystem, including service to around 400,000 people in Pacific Palisades, the Santa Monica Mountains, and West Los Angeles. History The reservoirs are owned by the Los Angeles Department of Water and Power. The main reservoir, which is the lower reservoir and the larger of the two, is situated south of the upper reservoir. It was designed and built in 1924 by the Los Angeles Department of Water and Power's water branch, the Bureau of Water Works and Supply (BWWS).23rd Annual Report of the ...

Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravity, gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the #Phase and amplitude, phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see ''#Timing, Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal cycle, diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cubic Meters Per Second
A cubic metre per second (m3s−1, m3/s, cumecs or cubic meter per second in American English) is the unit of volumetric flow rate in the International System of Units (SI) equal to that of a stere or cube with sides of in length exchanged or moving each second. It is popularly used for water flow, especially in rivers and streams, and fractions for HVAC values measuring air flow. The term cumec is also used, as shorthand for "Cubic metres per second", with the plural form ''cumecs'' also common in speech. It is commonly used between workers in the measurement of water flow through natural streams and civil works, but rarely used in writing. Data in units of cumec are used along the y-axis or vertical axis of a flow hydrograph, which describes the time variation of discharge of a river (the mean velocity multiplied by cross-sectional area). A moderately sized river discharges in the order of 100 cumecs. Conversions References See also * Standard litre per minute * Convers ...

Mediterranean Climate
A Mediterranean climate (also called a dry summer temperate climate ''Cs'') is a temperate climate sub-type, generally characterized by warm, dry summers and mild, fairly wet winters; these weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location. This climate type's name is in reference to the coastal regions of the Mediterranean Sea within the Mediterranean Basin, where this climate type is most prevalent. The "original" Mediterranean zone is a massive area, its western region beginning with the Iberian Peninsula in southwestern Europe and coastal regions of northern Morocco, extending eastwards across southern Europe, the Balkans, and coastal Northern Africa, before reaching a dead-end at the Levant region's coastline. Mediterranean climate zones are typically located along the western coasts of landmasses, between roughly 30 and 45 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate
Climate is the long-term weather pattern in an area, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude/longitude, terrain, altitude, land use and nearby water bodies and their currents. Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme was the Köppen climate classification. The Thornthwaite system, in use since 1948, incorporates evapotranspiration along with temperature ...

Storm Drain
A storm drain, storm sewer (United Kingdom, United States, U.S. and Canada), surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to Drainage, drain excess rain and ground water from impervious surfaces such as paved streets, car parks, parking lots, footpaths, sidewalks, and roofs. Storm drains vary in design from small residential dry wells to large municipal systems. Drains receive water from street gutters on most motorways, freeways and other busy roads, as well as towns in areas with heavy rainfall that leads to flooding, and coastal towns with regular storms. Even gutters from houses and buildings can connect to the storm drain. Many storm drainage systems are gravity sewers that drain untreated storm water into rivers or streams—so it is unacceptable to pour hazardous substances into the drains. Storm drains sometimes cannot manage the quantity of rain that falls in heavy rains or storms. Inundated drai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benedict Canyon

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...
