The Mississippi River alone experiences an alarming amount of erosion today. The land loss of the Mississippi is simply occurring at a much faster rate than it did before the industrial age, and any rising seas will yield a profound effect on the Mississippi River Delta. The degradation of the Mississippi River Delta results from river dredging for canals, less sediment being deposited, inundation by saltwater and erosion by waves from the Gulf of Mexico. The delta has also been altered by the construction of dams and levees along its course to prevent flooding of communities. Engineers have proposed creating new delta land over the next several decades by engineering river diversions.

The Sacramento–San Joaquin River Delta, or California Delta, is an expansive inland river delta and estuary in Northern California. The Delta is formed at the western edge of the Central Valley by the confluence of the Sacramento and San Joaquin rivers and lies just east of where the rivers enter Suisun Bay. The Delta is recognized for protection by the California Bays and Estuaries Policy.[1] The city of Stockton is located on the San Joaquin River on the eastern edge of the delta. The total area of the Delta, including both land and water, is about 1,100 square miles (2,800 km2).The Delta was formed by the raising of sea level following glaciation, leading to the accumulation of Sacramento and San Joaquin River sediments behind the Carquinez Strait, the sole outlet from the Central Valley to San Pablo and San Francisco Bays and the Pacific Ocean. The narrowness of the Carquinez Strait coupled with tidal action has caused the sediment to pile up, forming expansive islands. Geologically, the Delta has existed for about 10,000 years, since the end of the last Ice Age. In its natural state, the Delta was a large freshwater marsh, consisting of many shallow channels and sloughs surrounding low islands of peat and tule.Since the mid-19th century, most of the region has been gradually claimed for agriculture. Wind erosion and oxidation have led to widespread subsidence on the Central Delta islands; much of the Delta region today sits below sea level, behind levees earning it the nickname "California's Holland".[2][3] Much of the water supply for central and southern California is also derived from here via pumps located at the southern end of the Delta, which deliver water for irrigation in the San Joaquin Valley and municipal water supply for southern California.

A river delta is a landform that forms from deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.

The term delta comes from the upper-case Greek letter delta (Δ), which is shaped like a triangle. Deltas with this triangular or fan shape are called arcuate (arc-like) deltas. The Nile River forms an arcuate delta as it empties into the Mediterranean Sea.
There are four main types of deltas classified by the processes that control the build-up of silt: wave-dominated, tide-dominated, Gilbert deltas, and estuarine deltas. In a wave-dominated delta, the movement of waves controls a delta's size and shape.

Restoring deltas takes considerable amounts of time and money. Even with coastal restoration attempts, deltas around the world may not be able to withstand such rapid change and population growth. Nevertheless, scientists are working hard to find ways to protect river deltas while keeping their surrounding populations sustainable. New methods are being used to predict how river deltas change shape by measuring ratios of river flow rate, sediment fluctuation and ocean wave influence. When engineers know these kinds of data, they can understand the effects of manmade structures such as dams and levees on river deltas. The future of river delta regions depends on more research and funding to keep these important areas healthy and productive for the future.

River deltas do not cover much actual land area. However, they tend to host many resources that both people and animals rely on; some river delta areas host millions of people. River deltas provide food, ports and transportation for many countries.

River deltas are some of the most biologically productive places in the world. The soil tends to be rich, and plants flourish there. River deltas support fish nurseries, fisheries, crustaceans, forests and crops such as tea and rice. Ecosystems like wetlands and mangrove forests depend on a stable river delta. Animals like birds, insects and sometimes even large predators rely on the ecosystem of a delta.

River deltas are one of nature’s cleanup crews. The deltas work to absorb storm and flood runoff as well as to clean water traveling through them.

Changes in the environment and climate can alter river deltas. When channels are dug into rivers, or wetlands are developed, greater amounts of erosion occur. This means more sediment will wash out to sea much faster, rather than slowly filling in the delta land. Increased sea level and stronger hurricanes also threaten the sensitive delta areas. More water can inundate further inland when deltas begin to sink.

Some river deltas experience overdevelopment by people or restriction by water management such as dams. This causes ecosystems to undergo drastic change in relatively short periods of time. For example, the Colorado River was dammed in the 20th century, preventing it from flowing into the Sea of Cortez in Mexico. Many species that once lived in the Colorado River Delta suffered from complete disappearance of their original habitat. In the case of the Nile River Delta, overmanagement combined with Mediterranean waves have led to rapid erosion of the delta that cannot be quickly restored.

The Mississippi River Delta is probably the most famous river delta in the United States. It is a bird-foot delta. The Mississippi River Delta hosts millions of people while also supporting a unique ecosystem. This delta is comprised of wetlands, barrier islands and estuaries that provide homes for many kinds of plants and animals.

Also in the United States, the Sacramento-San Joaquin River is an example of an inverted delta.

The Fraser River in Vancouver, Canada, the Rhine-Meuse-Scheldt Delta in the Netherlands and Pearl River Delta in China all coincide with large populations of people. The Yellow River in northern China is an example of an estuarine delta, and the Tiber River is an example of a cuspate delta located in Italy.

Far northern Lena Delta in Russia and the Yukon and Mackenzie Deltas in Canada are especially susceptible to increasing temperatures in the Arctic.

The Amazon and Columbia Rivers do not form true deltas because they meet strong waves at their mouths, preventing the settlement of alluvium needed.

In Botswana, the Okavango Delta represents an inland delta that flows into the Kalahari Desert.

A river delta is a landform at the mouth of a river.

River deltas can come in different types, depending on the amount of sediment they carries with it and the type of water they empty into. Shape also determines delta type.

One type of river delta is the wave-dominated delta, which is affected by strong waves. An example of this is the Nile River, which is strongly influenced by the Mediterranean Sea. Waves from the Mediterranean are stronger than the river’s force, which pushes sediment in such a way that the coast is smooth. The Nile River delta can also be classified as an arcuate delta, which is a triangular-shaped delta.

If a river delta is greatly affected by tides, that is called a tide-dominated delta. River deltas found in freshwater lakes are called Gilbert deltas.

When rivers do not fully empty into the ocean and form estuaries instead, those wetland environments are considered estuarine deltas.

A cuspate delta is a tooth-shaped delta.

Bird-foot deltas are deltas that have smaller portions of a river broken apart, called distributaries. They are so named because they resemble a bird foot. Bird-foot deltas get their shape from the force of the river being greater than that of ocean waves, so that alluvium deposits more quickly.

Inverted deltas occur when only one river reaches a sea or bay, but upstream several distributary rivers exist.

Inland deltas are far less common, and occur when a river empties onto dry land.

# data[].attributes.body
Deltas are located at river mouths. They usually exist at the mouth of a river entering an ocean. However, deltas can also be found where rivers meet a lake. While less common, sometimes deltas occur inland. Deltas can be found all over the world. However, not every river forms a delta. Fast-moving rivers do not tend to form deltas.

Deltas can be found at the mouths of rivers that carry large amounts of sediment. This sediment is called alluvium. Typically the river will slow down at this point. The delta takes the shape of a triangle or fan where the alluvium enters the ocean or lake. This fan is also called a deltaic lobe. The part of the delta that is underwater is called subaqueous, whereas the part above water is called subaerial.

Deltas are wetlands that form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river. Although very uncommon, deltas can also empty into land.  A river moves more slowly as it nears its mouth, or end. This causes sediment, solid material carried downstream by currents, to fall to the river bottom. The slowing velocity of the river and the build-up of sediment allows the river to break from its single channel as it nears its mouth. Under the right conditions, a river forms a deltaic lobe. A mature deltaic lobe includes a distributary network—a series of smaller, shallower channels, called distributaries, that branch off from the mainstream of the river.

The mouth of a river is where it meets an ocean, a lake or another river. If a river carries a great deal of silt, gravel, clay and sediment as it travels, and this settles out at its mouth, that area of land is called a delta. The word “delta” comes from the Greek letter, which looks like a triangle. As such, a river delta typically makes up a triangle-shaped piece of land.

Where is the Delta?

The California Delta is located east of the San Francisco Bay Area at the confluence of the Sacramento and San Joaquin rivers. Check out the interactive Google Map to learn more about the islands and water facilities in the Delta. We plan to continue to add new sites, photos and links to the map. Let us know if there is anything we should include.

Why does the Delta matter to every Californian?

Anyone in California who remotely follows water news or current events has no doubt heard about the Delta, and the multitude of problems and issues facing this vital region. These issues, if left unresolved, can have huge ramifications for the entire state, but it can be hard to understand just how this relatively small area in Northern California could be of such concern to those of us living in Southern California, or elsewhere in the state. Many Californians, including some who live in the region, don't even know where or what the Delta is, or why they should really care.

What could the Delta possibly have to do with me?

Well, a lot, actually. Everyone in California depends upon the Delta for something, be it drinking water, fresh produce or livestock, goods shipped over the highways and railways that transverse it, or gas and electricity that is carried in pipes and transmission lines. Wildlife also depends on the Delta, as it provides a crucial habitat for wildlife, and an important stop for migratory birds.

A river delta is formed at the mouth of a river where the river deposits the sediment load carried by it and drains into a slower moving or static body of water. This usually occurs when the river joins a sea, estuary, ocean, lake, reservoir or in rare cases a slower moving river. The deltas of rivers are usually highly fertile areas and thus some of the most densely populated settlements of humans are based on such deltas. Some example of major deltas of the world is the Nile River delta and the Ganges River delta.
