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 zone between river environments and maritime environments. They are subject both to marine influences—such as tides, waves, and the influx of saline water—and to riverine influences—such as flows of fresh water and sediment. The inflows of sea water and fresh water provide 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 began to rise about 10. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns, the banks of many estuaries are amongst the most heavily populated areas of the world, with about 60% of the worlds population living along estuaries and the coast. The word estuary is derived from the Latin word aestuarium meaning tidal inlet of the sea, there have been many definitions proposed to describe an estuary. However, this definition excludes a number of water bodies such as coastal lagoons. This broad definition also includes fjords, lagoons, river mouths, an estuary is a dynamic ecosystem having a connection to the open sea through which the sea water enters with the rhythm of the tides. The sea water entering the estuary is diluted by the water flowing from rivers. The pattern of dilution varies between different estuaries and depends on the volume of water, the tidal range. Drowned river valleys are known as coastal plain estuaries. In places where the sea level is rising relative to the land, sea water progressively penetrates into river valleys and this is the most common type of estuary in temperate climates. Well-studied estuaries include the Severn Estuary in the United Kingdom and the Ems Dollard along the Dutch-German border, the width-to-depth ratio of these estuaries is typically large, appearing wedge-shaped in the inner part and broadening and deepening seaward. Water depths rarely exceed 30 m, examples of this type of estuary in the U. S. are the Hudson River, Chesapeake Bay, and Delaware Bay along the Mid-Atlantic coast, and Galveston Bay and Tampa Bay along the Gulf Coast. They are relatively common in tropical and subtropical locations and these estuaries are semi-isolated from ocean waters by barrier beaches. Formation of barrier beaches partially encloses the estuary, with only narrow inlets allowing contact with the ocean waters, bar-built estuaries typically develop on gently sloping plains located along tectonically stable edges of continents and marginal sea coasts. They are extensive along the Atlantic and Gulf coasts of the U. S. in areas with active coastal deposition of sediments, barrier beaches form in shallow water and are generally parallel to the shoreline, resulting in long, narrow estuaries

San Francisco Bay
–
San Francisco Bay is a shallow estuary in the U. S. state of California. It is surrounded by a region known as the San Francisco Bay Area, dominated by the large cities San Francisco, Oakland. San Francisco Bay drains water from approximately 40 percent of California and it then connects to the Pacific Ocean via the Golden Gate strait. However, this group of interconnected bays is often called the San Francisco Bay. The bay was designated a Ramsar Wetland of International Importance on February 2,2013, the bay covers somewhere between 400 and 1,600 square miles, depending on which sub-bays, estuaries, wetlands, and so on are included in the measurement. The main part of the bay measures 3 to 12 miles wide east-to-west and it is the largest Pacific estuary in the Americas. Later, wetlands and inlets were filled in, reducing the Bays size since the mid-19th century by as much as one third. Recently, large areas of wetlands have been restored, further confusing the issue of the Bays size, despite its value as a waterway and harbor, many thousands of acres of marshy wetlands at the edges of the bay were, for many years, considered wasted space. As a result, soil excavated for building projects or dredged from channels was often dumped onto the wetlands, from the mid-19th century through the late 20th century, more than a third of the original bay was filled and often built on. The idea was, and remains, controversial, there are five large islands in San Francisco Bay. Alameda, the largest island, was created when a shipping lane was cut in 1901 and it is now predominantly a bedroom community. Angel Island was known as Ellis Island West because it served as the point for immigrants from East Asia. It is now a park accessible by ferry. Mountainous Yerba Buena Island is pierced by a tunnel linking the east and west spans of the San Francisco–Oakland Bay Bridge, attached to the north is the artificial and flat Treasure Island, site of the 1939 Golden Gate International Exposition. From the Second World War until the 1990s, both served as military bases and are now being redeveloped. Isolated in the center of the Bay is Alcatraz, the site of the federal penitentiary. The federal prison on Alcatraz Island no longer functions, but the complex is a popular tourist site, despite its name, Mare Island in the northern part of the bay is a peninsula rather than an island. During the last ice age, the now filled by the bay was a large linear valley with small hills

East Bay (San Francisco Bay Area)
–
The eastern region of the San Francisco Bay Area, commonly referred to as the East Bay, includes cities along the eastern shores of the San Francisco Bay and San Pablo Bay. The region has grown to include inland communities in Alameda and Contra Costa Counties, with a population of roughly 2.5 million in 2010, it is the most populous subregion in the Bay Area. Oakland is the largest city in the East Bay and the third largest in the Bay Area, the city serves as a major transportation hub for the U. S. West Coast, and its port is the largest in Northern California, increased population has led to the growth of such large edge cities as Berkeley, Hayward, Concord and Fremont. The Transcontinental Railroad was completed in 1869 with its terminus at the newly constructed Oakland Long Wharf. Today the Port of Oakland is the Bay Areas largest port, in 1868, the University of California was formed from the private College of California and a new campus was built in what would become Berkeley. The 1906 San Francisco earthquake saw a number of refugees flee to the relatively undamaged East Bay. As the East Bay grew, the push to connect it with a permanent link than ferry service resulted in the completion of the San Francisco–Oakland Bay Bridge in 1936. The Bay Area saw further growth in the decades following World War II, the 1937 completion of the Caldecott Tunnel through the Berkeley Hills fueled growth further east, where there was undeveloped land. Cities in the Diablo Valley, including Concord and Walnut Creek, the addition of the BART commuter rail system in 1972 further encouraged development in increasingly far-flung regions of the East Bay. Today, the valleys east of the Berkeley Hills contain large affluent suburban communities such as Walnut Creek, San Ramon, the East Bay is not a formally defined region, aside from its being described as a region inclusive of Alameda and Contra Costa counties. As development moves generally eastward, new areas are described as being part of the East Bay, beyond the borders of Alameda County, the large population of Tracy is connected as a bedroom community housing commuters traveling to or through the East Bay. Except for some hills and ridges which exist as parklands or undeveloped land, and some farmland in eastern Contra Costa and Alameda Counties, the East Bay is highly urbanized. The East Bay shoreline is a corridor with several cities exceeding 100,000 residents, including Oakland, Hayward, Fremont, Richmond. In the inland valleys on the east side of the Berkeley Hills, the land is developed, particularly on the eastern fringe of Contra Costa county. In the inland valleys, the density is less and the cities smaller. The only cities exceeding 100,000 residents in the valleys are Antioch. The free East Bay Monthly has been published since 1970, in the early years of the evolution of USA Today, during the early 1980s, they operated regional newspapers, with the regions paper entitled East Bay Today

North Bay (San Francisco Bay Area)
–
The North Bay is a subregion of the San Francisco Bay Area, in California, United States. The largest city is Santa Rosa, which is the fifth-largest city in the Bay Area and it is the location of the Napa and Sonoma wine regions, and is by far the least populous and least urbanized part of the Bay Area. It consists of Marin, Napa, Solano, and Sonoma counties, several ferry routes operate between the North Bay and San Francisco, from terminals located in Sausalito, Tiburon, Larkspur, Vallejo and Angel Island. Commuter rail service from Fairfield to Sacramento and Oakland is provided by Amtrak on its Capitol Corridor line, plans for the development of the Sonoma-Marin Area Rail Transit, a fourteen station commuter rail line from Larkspur to Cloverdale, were approved by voters in November 2008. The area is said to have populated by Pomo Native Americans before European intervention. The Russians first settled the area at Fort Ross as a fur-trading post, the Bear Flag Revolt took place in the town of Sonoma, which is also the location of the last of the California Missions. The North Bay remained isolated and rural well into the 20th Century, the opening of the Golden Gate Bridge in the 1930s transformed Marin County from a dairy farming region into an upscale suburban area. Until the 1990s, the growth was at a gradual pace, with significant restrictions on development being imposed in Marin. The largest city in the North Bay is Santa Rosa, other major cities include, Vallejo San Rafael Fairfield Napa Novato Petaluma Rohnert Park North Coast AVA North Coast San Pablo Bay National Wildlife Refuge

The San Francisco Bay Area is a populous region surrounding the San Francisco and San Pablo estuaries in Northern California. The region encompasses the cities and metropolitan areas of San Jose, San Francisco. The Bay Areas nine counties are Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. The combined statistical area of the region is the second-largest in California, the fifth-largest in the United States, the Bay Area has the second-most Fortune 500 Companies in the United States, and is known for its natural beauty, liberal politics, entrepreneurship, and diversity. The eastern side of the bay, consisting of Alameda and Contra Costa counties, is known locally as the East Bay, the inner East Bay is more densely populated, with generally older buildings, and a more ethnically diverse population. The word Lamorinda was coined by combining the names of the cities it includes, Lafayette, Moraga, walnut Creek is situated east of Lamorinda and north of the San Ramon Valley and, together with Concord, Martinez, and Pleasant Hill comprises Central Contra Costa County. The cities of Antioch, Pittsburg, Brentwood, Oakley and the areas surrounding them comprise East Contra Costa County. The Tri-Valley consists of the Amador, the Livermore, and the San Ramon Valleys, dublin and Pleasanton comprise the Amador Valley, Livermore lies in the Livermore Valley, and the San Ramon Valley consists of Alamo, Danville, Diablo and its namesake, San Ramon. The outer East Bay is connected to the inner East Bay by BART, Interstate 580 to the south, and State Routes State Route 4 to the north, the outer East Bays infrastructure was mostly built up after World War II. This area remains largely white demographically, although the Hispanic and Filipino populations have grown significantly over the past 2–3 decades, the region north of the Golden Gate Bridge is known locally as the North Bay. This area encompasses Marin County, Sonoma County, Napa County, the city of Fairfield, being part of Solano County, is often considered the easternmost city of the North Bay. With few exceptions, this region is affluent, Marin County is ranked as the wealthiest in the state. The North Bay is relatively rural compared to the remainder of the Bay Area, with areas of undeveloped open space, farmland. Santa Rosa in Sonoma County is the North Bays largest city, with a population of 167,815 and a Metropolitan Statistical Area population of 466,891, making it the fifth-largest city in the Bay Area. The North Bay is the section of the Bay Area that is not currently served by a commuter rail service. The area from San Francisco to the Silicon Valley, geographically part of the San Francisco Peninsula, is known locally as The Peninsula, many of these families are of foreign background and have significantly contributed to the diversity of the area. Whereas the term peninsula technically refers to the entire geographical San Franciscan Peninsula, in local terms, San Francisco is surrounded by water on three sides, the north, east, and west. The city squeezes roughly 870,000 people in under 47 square miles, on any given day, there can be as many as 1 million people in the city because of the commuting population and tourism

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

Marshall. Sacramento grew quickly thanks to the protection of Sutters Fort, which was established by Sutter in 1839, the city was named after the Sacramento River, which forms its western border. The river was named by Spanish cavalry officer Gabriel Moraga for the Santísimo Sacramento, California State University, Sacramento, is the largest university in the city and one of 23 campuses in the California State University system. University of the Pacific is a university with one of its three campuses in Sacramento. In addition, the University of California, Davis, located in nearby Davis, operates its UC Davis Medical Center, nisenan and Plains Miwok Native Americans had lived in the area for perhaps thousands of years. Unlike the settlers who would eventually make Sacramento their home, these Native Americans left little evidence of their existence. Traditionally, their diet was dominated by acorns taken from the oak trees in the region, and by fruits, bulbs, seeds. In 1808, the Spanish explorer Gabriel Moraga discovered and named the Sacramento Valley, a Spanish writer with the Moraga expedition wrote, Canopies of oaks and cottonwoods, many festooned with grapevines, overhung both sides of the blue current. Birds chattered in the trees and big fish darted through the pellucid depths, the air was like champagne, and drank deep of it, drank in the beauty around them. The valley and the river were then christened after the Most Holy Sacrament of the Body and Blood of Christ, John Sutter first arrived on August 13,1839 at the divergence of the American and Sacramento Rivers with a Mexican land grant of 50,000 acres. The next year, he and his party established Sutters Fort, representing Mexico, Sutter called his colony New Helvetia, a Swiss inspired name, and was the political authority and dispenser of justice in the new settlement. Soon, the colony began to grow as more and more pioneers headed west, within just a few short years, John Sutter had become a grand success, owning a ten-acre orchard and a herd of thirteen thousand cattle. Fort Sutter became a stop for the increasing number of immigrants coming through the valley. In 1847, Sutter hired James Marshall to build a sawmill so that he could continue to expand his empire, Sutter received 2,000 fruit trees in 1847, which started the agriculture industry in the Sacramento Valley. In 1848, when gold was discovered by James W. Marshall at Sutters Mill in Coloma and he hired topographical engineer William H
