Charleston Harbor
The Charleston Harbor is an inlet (8 sq mi/20.7 km2) of the Atlantic Ocean at Charleston, South Carolina. The inlet is formed by the junction of Ashley River (South Carolina), Ashley and Cooper River (South Carolina), Cooper rivers at . Morris Island, Morris and Sullivan's Islands shelter the entrance. Charleston Harbor forms part of the Intracoastal Waterway. History Charleston Harbor was a major port of entry for slave ships transporting slaves from West Africa. Due to its status as a slave capital, “Scholars estimate that over forty percent of all enslaved Africans sent to North America entered through Charleston Harbor — making Charleston the largest North American point of disembarkation for the trans-Atlantic slave trade.” The harbor contains Fort Sumter, the site of the first shots of the American Civil War. Charleston Harbor was also the site of the first successful submarine attack in history on February 17, 1864, when the ''H.L. Hunley'' made a daring Sin ...

Sinking Of USS Housatonic
The Sinking of USS ''Housatonic'' on 17 February 1864 during the American Civil War was an important turning point in naval warfare. The Confederate States Navy submarine, made her first and only attack on a Union Navy warship when she staged a clandestine night attack on in Charleston harbor. ''H.L. Hunley'' approached just under the surface, avoiding detection until the last moments, then embedded and remotely detonated a spar torpedo that rapidly sank the sloop-of-war with the loss of five Union sailors. ''H.L. Hunley'' became renowned as the first submarine to successfully sink an enemy vessel in combat, and was the direct progenitor of what would eventually become international submarine warfare, although the victory was Pyrrhic and short-lived, since the submarine did not survive the attack and was lost with all eight Confederate crewmen. Sinking On the evening of 17 February 1864, made her first mission against an enemy vessel during the American Civil War. Armed w ...

List Of Deepest Natural Harbours
This article presents a non-exhaustive list of the world’s deepest natural harbours. Often formed by flooded estuary, estuaries, ria, rias, fjords, or coastal basins, natural harbours are valued for their protection from ocean swell, deep Navigability, navigable waters, and Strategic geography, strategic positioning. Deep natural harbours have historically played a critical role in naval strategy, military and economy, commercial development, contributing to the rise of major port city, port cities. Their natural shelter often reduces the need for artificial structures such as Breakwater (structure), breakwaters and Dredging, dredged channels. List parameters This list ranks harbours solely by their natural average and maximum depths. Artificially deepened deep water ports are excluded unless their depth is primarily natural. Other characteristics such as surface area, catchment, or shipping volume are not considered. Depth rationale For the purposes of this list, a deep natur ...

Charleston, South Carolina In The American Civil War
Charleston, South Carolina, played a pivotal role at the start of the American Civil War as a stronghold of secession and an important Atlantic port for the Confederate States of America. The first shots of the conflict were fired there by cadets of The Citadel, who aimed to prevent a ship from resupplying the U.S. Army soldiers garrisoned at Fort Sumter. Three months later, a large-scale bombardment of Fort Sumter ignited a nationwide call to quell the rebellion. U.S. Army and Navy troops made repeated, concerted efforts to degrade the city fortifications throughout the war. Still, they would only retake control over and liberate the city in the conflict's final months. The prolonged struggle substantially damaged the city. Early war years According to the '' 1860 Census'', Charleston was the 22nd largest city in the United States, with a population of 40,522. As the 1814 Burning of Washington had shown, America's coastal cities were vulnerable to a hostile fleet. The United S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Society Of Civil Engineers
The American Society of Civil Engineers (ASCE) is a tax-exempt professional body founded in 1852 to represent members of the civil engineering profession worldwide.

Post-Panamax
Panamax and New Panamax (or Neopanamax) are terms for the size limits for ships traveling through the Panama Canal. The limits and requirements are published by the Panama Canal Authority (ACP) in a publication titled "Vessel Requirements". These requirements also describe topics like exceptional dry seasonal limits, propulsion, communications, and detailed ship design. The allowable size is limited by the width and length of the available lock chambers, by the depth of water in the canal, and by the height of the Bridge of the Americas since that bridge's construction, along with the clearance under the Atlantic and Centennial Bridges since their constructions in 2019 and 2004 respectively. These dimensions give clear parameters for ships destined to traverse the Panama Canal and have influenced the design of cargo ships, naval vessels, and passenger ships. Panamax specifications have been in effect since the opening of the canal in 1914. In 2009, the ACP published the " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mean Lower Low Water
A chart datum is the water surface serving as origin (or coordinate surface) of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. Common chart datums are ''lowest astronomical tide'' (LAT)Australian Bureau of MeteorologNational Tide Centre Glossary(retrieved 30 April 2013) and ''mean lower low water'' (MLLW). In non-tidal areas, e.g. the Baltic Sea, mean sea level (MSL) is used. A chart datum is a type of vertical datum and must not be confused with the horizontal datum for the chart. However, it is necessarily an equigeopotential (a water "level surface"): the chart datum is tilted across smaller to larger tidal range regions; in rivers, it is a sloping and undulating surface following the low stage. Definitions The following tidal phases are commonly used in the definition of chart datums. Lowest and highest astronomical tide ...

South Carolina Ports Authority
The South Carolina Ports Authority (SCPA) owns and operates public seaport facilities in Charleston, as well as Inland Ports in Greer, South Carolina, and Dillon, South Carolina. Established by the South Carolina General Assembly in 1942, it is authorized and charged with promoting, developing, constructing, equipping, maintaining and operating the harbors and seaports within the State of South Carolina. An economic development engine for the State, the South Carolina Ports Authority handles international commerce valued at more than $75 billion annually while receiving no direct taxpayer subsidy. According to a 2023 economic impact study conducted by University of South Carolina Darla Moore School of Business research economist and professor Dr. Joseph Von Nessen, port operations facilitate 260,000 jobs across South Carolina (one in every 9 jobs) paying 23% higher than the state's average wage. The study attributes nearly $87 billion in annual statewide economic activity to port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jetty
A jetty is a man-made structure that protrudes from land out into water. A jetty may serve as a breakwater (structure), breakwater, as a walkway, or both; or, in pairs, as a means of constricting a channel. The term derives from the French language, French word ', "thrown", signifying something thrown out. For regulating rivers Wing dams Jetties of one form, wing dams, are extended out, opposite one another, from each bank of a river, at intervals, to contract a wide channel (geography), channel, and concentrate the current to deepen the channel. 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 Sea, 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 v ...
