Stream
–
A stream is a body of water with a current, confined within a bed and banks. Streams are important as conduits in the cycle, instruments in groundwater recharge. The biological habitat in the vicinity of a stream is called a riparian zone. Given the status of the ongoing Holocene extinction, streams play an important corridor role in connecting fragmented habitats, the study of streams and waterways in general is known as surface hydrology and is a core element of environmental geography. Brook A stream smaller than a creek, especially one that is fed by a spring or seep and it is usually small and easily forded. A brook is characterised by its shallowness and its bed being composed primarily of rocks, creek In North America, Australia and New Zealand, a small to medium-sized natural stream. Sometimes navigable by motor craft and may be intermittent, in parts of Maryland, New England, the UK and India, a tidal inlet, typically in a salt marsh or mangrove swamp, or between enclosed and drained former salt marshes or swamps. In these cases, the stream is the stream, the course of the seawater through the creek channel at low. River A large natural stream, which may be a waterway, runnel the linear channel between the parallel ridges or bars on a shoreline beach or river floodplain, or between a bar and the shore. Tributary A contributory stream, or a stream which does not reach the sea, sometimes also called a branch or fork. There are a number of names for a stream. Allt is used in Highland Scotland, beck is used in Yorkshire, Lancashire, Dumfriesshire, Cumbria, Norfolk, and Lincolnshire. Bourne or winterbourne is used in the chalk downland of southern England, brook is used in the Midlands, Lancashire and Cheshire. Burn is used in Scotland and North East England, gill or ghyll is seen in the north of England and other areas influenced by Old Norse. Rivulet is an term encountered in Victorian era publications, stream is used in Southern England. Syke is used in lowland Scotland and Cumbria for a seasonal stream, branch is used to name streams in Maryland and Virginia. Falls is also used to name streams in Maryland, for streams/rivers which have waterfalls on them, little Gunpowder Falls and The Jones Falls are actually rivers named in this manner, unique to Maryland. Kill in New York, Pennsylvania, Delaware, and New Jersey comes from a Dutch language word meaning riverbed or water channel, run in Ohio, Maryland, Michigan, New Jersey, Pennsylvania, Virginia, or West Virginia can be the name of a stream

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

California
–
California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California also has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence. The western portion of Alta California then was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their organization with bands, tribes, villages. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years later English explorer Francis Drake also explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565

Contra Costa County, California
–
Contra Costa County is a county in the state of California in the United States. As of the 2010 census, the population was 1,049,025, the name is Spanish for opposite coast, referring to its position on the other side of the bay from San Francisco. Contra Costa County is included in the San Francisco–Oakland–Hayward, CA Metropolitan Statistical Area and it occupies the northern portion of the East Bay region and is primarily suburban. In the northern part of the county, significant coal and sand deposits were formed in even earlier geologic eras, other areas of the county have ridges exposing ancient but intact seashells, embedded in sandstone layers alternating with limestone. Layers of volcanic ash ejected from geologically recent but now extinct volcanoes, compacted and now tilted by compressive forces, may be seen at the site of some road excavations. This county is an agglomeration of several distinct geologic terranes, as is most of the greater San Francisco Bay Area, younger deposits at middle altitudes include pillow lavas, the product of undersea volcanic eruptions. There is an extensive but little recorded human history pre-European settlement in this area, the earliest definitively established occupation by modern man appears to have occurred six to ten thousand years ago. However, there may have been human presence far earlier, at least as far as non–settling populations are concerned, extensive trading from tribe to tribe transferred exotic materials such as obsidian throughout the region from far distant Californian tribes. Unlike the nomadic Native American of the Great Plains it appears that these tribes did not incorporate warfare into their culture but were generally cooperative. Within these cultures the concept of individual or collective land ownership was nonexistent, early European settlers in the region, however, did not record much about the culture of the natives. Most of what is known comes from preserved contemporaneous and excavated artifacts. Although there were no missions established within this county, Spanish influence here was direct and extensive, in 1821 Mexico gained independence from Spain. Mission lands extended throughout the Bay Area, including portions of Contra Costa County, between 1836 and 1846, during the era when California was a province of independent Mexico, the following 15 land grants were made in Contra Costa County. Rough surveying was based on a map, or diseño, measured by streams, shorelines, and/or horseman who marked it with rope, lands outside rancho grants were designated el sobrante, as in surplus or excess, and considered common lands. The law required the construction of a house within a year, fences were not required and were forbidden where they might interfere with roads or trails. Locally a large family required roughly 2000 head of cattle and two leagues of land to live comfortably. Foreign entrepreneurs came to the area to provide goods that Mexico couldn’t, Rancho Canada de los Vaqueros was granted to Francisco Alviso, Antonio Higuera, and Manuel Miranda. Two ranchos, both called Rancho San Ramon, were granted by the Mexican government in the San Ramon Valley, in 1833, Bartolome Pacheco and Mariano Castro shared the two square league Rancho San Ramon

San Pablo lies on a plain between the northern end of the Berkeley Hills and San Pablo Bay, although the city limits do not extend to the bayshore. The city is traversed by two creeks, Wildcat Creek and San Pablo Creek, both of which originate in the ranges to its southeast. The minor Rheem Creek also runs through the city and it is also traversed along its northeast limits by the Hayward Fault, a major branch of the San Andreas Fault which lies to the west.

The city was incorporated on August 7,1905, under the McLaughlin Administration, Richmond was the largest city in the United States served by a Green Party mayor. As of the 2010 U. S. Census, the population is at 103,710. The largest, Richmond, Virginia, is the namesake of the California city, the Ohlone Indians were the first inhabitants of the Richmond area, settling an estimated 5,000 years ago. The name Richmond appears to predate actual incorporation by more than fifty years, the Atchison, Topeka and Santa Fe Railroad had its terminus at Richmond. The first post office opened in 1900, Richmond was founded and incorporated in 1905, carved out of Rancho San Pablo, from which the nearby town of San Pablo inherited its name. Until the enactment of prohibition in 1919, the city had the largest winery in the world, in the 1920s the Ku Klux Klan was active in the city. In 1930 the Ford Motor Company opened a plant called Richmond Assembly Plant which moved to Milpitas in the 1960s. The old Ford plant has been a National Historic Place since 1988, the city was a small town at that time, until the onset of World War II which brought on a rush of migrants and a boom in the industrial sector. Standard Oil set up here in 1901, including a what is now the Chevron Richmond Refinery and tank farm. There is a pier into San Francisco Bay south of Point Molate for oil tankers, the western terminus of the Santa Fe Railroad was established in Richmond with ferry connections at Ferry Point in the Brickyard Cove area of Point Richmond to San Francisco. Many of these lived in specially constructed houses scattered throughout the San Francisco Bay Area, including Richmond, Berkeley. A specially built rail line, the Shipyard Railway, transported workers to the shipyards, kaisers Richmond shipyards built 747 Victory and Liberty ships for the war effort, more than any other site in the U. S. The city broke many records and even built one Liberty ship in a five days. On average the yards could build a ship in thirty days, the medical system established for the shipyard workers at the Richmond Field Hospital eventually became todays Kaiser Permanente HMO. It remained in operation until 1993 when it was replaced by the modern Richmond Medical Center hospital, Point Richmond was originally the commercial hub of the city, but a new downtown arose in the center of the city. It was populated by many department stores such as Kress, J. C. Penney, Sears, Macys, during the war the population increased dramatically and peaked at around 120,000 by the end of the war. Once the war ended the workers were no longer needed

Tilden Regional Park
–
Tilden Regional Park, also known as Tilden Park or Tilden /ˈtɪldən/, is a 2, 079-acre regional park in the East Bay, part of the San Francisco Bay Area in California. It is between the Berkeley Hills and San Pablo Ridge, the park is managed by the East Bay Regional Park District, created from the first land the District purchased in 1936. Tilden Regional Park was named in honor of Charles Lee Tilden, Tilden Park is largely located within unincorporated areas of Contra Costa County, while parts of the park are within the cities of Oakland and Berkeley. Its steep valleys and dense stands of timber offer a rare wilderness experience so close to the city and its high ridges and peaks give wide views over the San Francisco Bay and inland across other preserved land to Mount Diablo. The eastern limit of the park is approximately at the crest of the San Pablo Ridge, the western boundary nearly follows the crest of the Berkeley Hills. Parts of the land had previously been cleared for agricultural use. In many places, exotic trees such as eucalyptus have been planted, there are also some relatively recently planted stands of giant sequoia. However, current conservation efforts are aimed at restoring native vegetation as much as possible, the East Bay Regional Parks District uses grazing as a means of vegetation reduction, with a herd of goats grazing each summer in Tilden. AC Transit bus line 67 from the Berkeley BART station runs into the park on weekends, the bus line stops at the Tilden Nature Area/Little Farm, Lone Oak Road, Lake Anza/Merry-Go-Round, and the Brazilian Room/Botanic Garden before returning to Berkeley. Prior to being a park, the lands that are now Tilden Park were ancestral lands of Ohlone Indians. Spanish explorers and Mexican ranchos drove the Ohlone off the land as ranching became the dominant activity in Wildcat Canyon, american ranchers of the late 1800s and early 1900s included the Curran family ranch and the Sweet Briar Dairy. The eucalyptus plantations within the park were planted around 1910 by Frank C, havens Eucalyptus, Mahogany, & Land Company. The first parkland was purchased by the East Bay Regional Park District from the East Bay Municipal Utility District on June 4,1936, the 2,162 acres purchased included land for Tilden Park, Lake Temescal and Robert Sibley Volcanic Regional Preserve. Upper Wildcat Canyon was officially named Charles Lee Tilden Regional Park on July 16,1936. At the June 4,1936 board meeting of East Bay Regional Park District, the meeting that authorized the land purchase. In doing so, they met their matching fund obligation in order to qualify for $1 million in relief funds for park development. From 1935 to 1941 a Civilian Conservation Corps camp, Camp Wildcat Canyon was located in what is now the Tilden Nature Area, the CCC crews built much of the parks earlier infrastructure and features including roads, trails, bridges, picnic areas, and golf course. Works Progress Administration crews built the Lake Anza dam and stone buildings including restrooms, the original Lake Anza beach house, the aesthetic of the park today is directly derived from the original work performed by the CCC and WPA

Castro Creek
–
Castro Creek is a creek in Richmond, California in the western part of the city adjacent to the Chevron Oil Refinery. Wildcat Creek drains into it directly and though other Wildcat Marsh tributaries into Castro Cove of San Pablo Bay, the creek drains from the drainage basin of the surrounding area and was once part of the channel that separated the island of Point Richmond with the mainland. The stream is waterway is named after Don Víctor Castro the owner of the area when it was Rancho San Pablo, the Chevron Richmond Refinery dumps wastewater into the creek routinely 500 yards north of the confluence with Wildcat Creek and also in a drainage. Other waste may only be dumped into the creek through a ditch on Castro Street during high intensity rainfall. Castro Creek is a fishing, shell-fishing, and recreation area and its estuarine habitat is essential habitat for several endangered species. The creek is also a spawning and migration center. Castro Cove has become polluted from 85 years of unbridled discharge of waste waters with PAHs.

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation
