Indian River Bay
Indian River Bay is a body of water in Sussex County, Delaware. It is part of Delaware's inland bay system, along with Little Assawoman Bay and Rehoboth Bay. Fed by the Indian River at its western end, the bay is connected to the Atlantic Ocean to the east via the Indian River Inlet. A natural waterway that shifted up and down a two-mile (3.2 km) stretch of the coast until 1928, the inlet was kept in its current location by dredging between 1928 and 1937, and in 1938 was fixed in place by the construction of jetties. The Charles W. Cullen Bridge, commonly known as the Indian River Inlet Bridge, spans the inlet. Indian River Bay is unique among Delaware's inland bays in that it is a drowned river valley, whereas Delaware's other bays are estuaries built on sand bars.Delaware Inland Bays Compreh ...

Indian River Inlet Bridge
The Indian River Inlet Bridge (officially the Charles W. Cullen Bridge) is a cable-stayed bridge located in Sussex County, Delaware, in the United States. It carries four lanes of Delaware Route 1 (DE 1) over the Indian River Inlet between the Indian River Bay and the Atlantic Ocean. The bridge also carries Delaware Bicycle Route 1 (Bike Route 1) across the inlet. The bridge is within Delaware Seashore State Park between Dewey Beach and Bethany Beach. The Indian River Inlet Bridge is maintained by the Delaware Department of Transportation (DelDOT). The bridge is long and wide, with a span of and overhead clearance of . Prior to the current bridge, four other bridges have spanned the Indian River Inlet, opened in 1934, 1940, 1952, and 1965, the latter widened by an additional span added in 1976. All were known informally as the Indian River Inlet Bridge, and all but the first officially were named the Charles W. Cullen Bridge. The 1965 bridge, a steel girder bridge, was ...

Assawoman Canal
The Assawoman Canal is a canal in Sussex County, Delaware. The canal links the Indian River Bay to the north with the Little Assawoman Bay to the south. It is bordered by Bethany Beach and South Bethany to the east and Ocean View to the west. Because of it, Fenwick Island is detached from the Delaware mainland. First proposed in 1884, the Assawoman Canal was constructed by the U.S. Army Corps of Engineers in 1891 for the purpose of moving goods by boat without having to travel into the Atlantic Ocean. The canal was initially dug by hand in the 1890s by immigrant labor. The canal was not dredged from the 1950s until 2006. By the early 2000s, it was no longer deep enough to handle the boat traffic that once passed through it when it was part of the Intracoastal Waterway The Intracoastal Waterway (ICW) is a inland waterway along the Atlantic and Gulf of Mexico coasts of the United States, running from Massachusetts southward along the Atlantic Seaboard and around the south ...

Urban Runoff
Urban runoff is surface runoff of rainwater, landscape irrigation, and car washing created by urbanization. Impervious surfaces (roads, parking lots and sidewalks) are constructed during land development. During rain , storms and other precipitation events, these surfaces (built from materials such as asphalt and concrete), along with rooftops, carry polluted stormwater to storm drains, instead of allowing the water to percolate through soil. This causes lowering of the water table (because groundwater recharge is lessened) and flooding since the amount of water that remains on the surface is greater.Water Environment Federation Alexandria, VA; an American Society of Civil Engineers Reston, VA [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holts Landing State Park
Holts Landing State Park is a Delaware state park northwest of Bethany Beach, Sussex County, Delaware, USA. Prior to becoming a state park the land of Holts Landing State Park was the Holt family farm. The Holts sold the land to the state of Delaware in 1957 and Holts Landing State Park was opened to the public in 1965. The park is on the southern shore of Indian River Bay. Holts Landing State Park is open for year-round recreation and features the only pier on the east coast of Delaware that has been purpose-built for crabbing, the recreational harvesting of blue crabs. History Holts Landing State Park, on Indian River Bay, has long been a center of crabbing, fishing, hunting, and farming dating back to the Pre-Columbian history of what is now southeastern Delaware. Native peoples took advantage of the abundant seafood that was harvested in the shallow waters of the inland bays. They also hunted wildlife in the surrounding marshes and forests.

Delaware Seashore State Park
Delaware Seashore State Park is located near Dewey Beach, in Delaware, United States. It is bounded on the east by the Atlantic Ocean and on the west by Rehoboth Bay and Indian River Bay. The park covers . It is a major attraction for millions of visitors who come to the Delaware Beaches for water-related activities. Delaware Seashore State Park was created in 1965. History The land in Delaware Seashore State Park saw frequent natural changes in the location of the inlet between the inland bays and the Atlantic Ocean. As a result, it was difficult to travel across this stretch of land. In 1939, two jetties were built to stabilize the Indian River Inlet at its present location. Indian River State Park was created by the State Park Commission in 1965, with the name becoming Delaware Seashore State Park in 1967. In 1966, the strip of land between the Little Assawoman Bay to the west and the Atlantic Ocean to the east between South Bethany and Fenwick Island became a separate sout ...

Sand Bar
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar or quite different from how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, this term refers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...

Drowned River Valley
A ria (; gl, ría) is a coastal inlet formed by the partial submergence of an unglaciated river valley. It is a drowned river valley that remains open to the sea. Definitions Typically rias have a dendritic, treelike outline although they can be straight and without significant branches. This pattern is inherited from the dendritic drainage pattern of the flooded river valley. The drowning of river valleys along a stretch of coast and formation of rias results in an extremely irregular and indented coastline. Often, there are naturally occurring islands, which are summits of partly submerged, pre-existing hill peaks. (Islands may also be artificial, such as those constructed for the Chesapeake Bay Bridge-Tunnel.) A ria coast is a coastline having several parallel rias separated by prominent ridges, extending a distance inland.Goudie, A. (2004) ''Encyclopedia of Geomorphology.'' Routledge.

Jetty
A jetty is a structure that projects from land out into water. A jetty may serve as a breakwater, as a walkway, or both; or, in pairs, as a means of constricting a channel. The term derives from the French word ', "thrown", signifying something thrown out. For regulating rivers Another form of jetties, wing dams are extended out, opposite one another, ''from each bank of a river'', at intervals, to contract a wide channel, and by concentration of the current to produce a deepening. At the outlet of tideless rivers Jetties have been constructed on each side of the outlet river of some of the rivers flowing into the Baltic, with the objective of prolonging the scour of the river and protecting the channel from being shoaled by the littoral drift along the shore. Another application of parallel jetties is in lowering the bar in front of one of the mouths of a deltaic river flowing into a tide — a virtual prolongation of its less sea, by extending the scour of the rive ...

Sussex County, Delaware
Sussex County is located in the southern part of the U.S. state of Delaware, on the Delmarva Peninsula. As of the 2020 census, the population was 237,378. The county seat is Georgetown. The first European settlement in the state of Delaware was founded by the Dutch in 1631 near the present-day town of Lewes on the Atlantic Coast. However, Sussex County was not organized until 1683 under English colonial rule. Sussex County is included in the Salisbury, MD-DE Metropolitan Statistical Area which encompasses much of central Delmarva. History Beginnings Archaeologists estimate that the first inhabitants of Sussex County, the southernmost county in Delaware, arrived between 10,000 and 14,000 years ago. Various indigenous cultures occupied the area, especially along the river and the coast, often having seasonal fishing villages. Historic Native Americans in Sussex County were members of Algonquian-speaking tribes, as were most coastal peoples along the Atlantic Coast. By the ...

Dredging
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.
