South San Ramon Creek
South San Ramon Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 15, 2011 southward-flowing stream in Alameda County and southern Contra Costa County, in the East Bay region of northern California. The creek is a tributary to Arroyo de la Laguna, flowing in the western Livermore Valley through Dublin and Pleasanton. Geography South San Ramon Creek drains the land area generally lying above the Bishop Subbasin of the Livermore Valley Groundwater Basin. The Bishop Subbasin comprises of valley lands in the far northwestern portion of Livermore Valley Ground Water Basin. The Bishop Subbasin lies entirely within Contra Costa County, is drained by, and is a portion of that area locally designated as San Ramon Valley. The subbasin is bounded on the east and west by rolling hills composed of sediments of the Tassajara Formation. The creek is being actively protected as of 2007, by the city of San Ramon a ...

Bishop Subbasin
The Bishop Subbasin is an aquifer that resides between two subsurface structures of the Tassajara Formation in the northern extremity of the Amador Valley, California. This aquifer is a sub-unit of the Livermore-Amador Groundwater Basin. The Bishop Subbasin is associated with the locale of San Ramon, California in Contra Costa County. The Bishop Subbasin along with the Mocho Subbasin is one of the aquifers in the Livermore Valley that has been studied the most heavily for benefits of injection of reclaimed reverse osmosis waters.

Tributaries Of Alameda Creek
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...

Rivers Of Contra Costa County, California
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

Iron Horse Regional Trail
The Iron Horse Regional Trail is a rail trail for pedestrians, horse riders and bicycles in the East Bay Area in California. This trail is located in inland central Alameda and Contra Costa counties, mostly following a Southern Pacific Railroad right of way established in 1891 and abandoned in 1977. The two counties purchased the right of way at that time, intending to use it as a transportation corridor; the Iron Horse Trail was first established in 1986. In 2003, BART proposed to also use the right-of-way for a DMU line from Walnut Creek station to Tracy via Pleasanton. The trail passes through the cities of Pleasanton, Dublin, San Ramon, Danville, Alamo, Walnut Creek, Pleasant Hill and Concord. When completed, the trail will span from Livermore in central Alameda County to Suisun Bay at the northern edge of Contra Costa County, a distance of over connecting two counties and nine communities. The trail also directly connects to both the Dublin/Pleasanton and Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riparian Zone
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important natural b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Ramon Valley
The San Ramon Valley is a valley and region in Contra Costa County and Alameda County, in the East Bay region of the San Francisco Bay Area in northern California. Geography The valley is between the Oakland Hills on the west, and the Diablo Range on the east. The valley's population is around 130,000 people. The cities of San Ramon and Danville, as well as the southern edge of Walnut Creek are located in the valley, as are the census-designated places (CDPs) of Alamo, Blackhawk, Camino Tassajara and Diablo. Interstate 680 serves as the primary transportation route for the area. The Iron Horse Regional Trail also runs the length of the valley.

Livermore Valley
The Livermore Valley, historically known as the Valle de San José (Valley of San José), is a valley in Alameda County, California, located in the East Bay region. The city of Livermore is located in the valley. Geography The valley is bounded by the Diablo Range on the north, east, and south; and is linked to the west with the Amador Valley. Watercourses draining the Livermore Valley include Arroyo Mocho, Arroyo Valle, Arroyo Seco, and Arroyo Las Positas. Wine Country The southern side of Livermore is wine country. Wineries in the area include Wente Vineyards and Concannon Vineyards. Laboratories In the east of Livermore is the Lawrence Livermore Laboratory. Element 116 on the periodic table, Livermorium, is named after this laboratory. Sandia Laboratory is also located in eastern Livermore. Due to these laboratories, much of eastern Livermore is off-limits to the general public. History Livermore Valley was named after Robert Livermore, an immigrant American ranch ...
