Flood Barrier
A flood barrier, surge barrier or storm surge barrier is a specific type of floodgate, designed to prevent a storm surge or spring tide from flooding the protected area behind the barrier. A surge barrier is almost always part of a larger flood protection system consisting of floodwalls, levees (also known as dikes), and other constructions and natural geographical features. Flood barrier may also refer to barriers placed around or at individual buildings to keep floodwaters from entering the buildings. Examples Delta Works The Delta Works in the Netherlands is the largest flood protection project in the world. This project consists of a number of surge barriers, the Oosterscheldekering being the largest surge barrier in the world, long. Other examples include the Maeslantkering, Haringvlietdam and the Hartelkering. Thames Barrier The Thames Barrier is the world's second largest movable flood barrier (after the Oosterscheldekering and the Haringvlietdam) and is ...

Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.

Coastal Flooding
Coastal flooding normally occurs when dry and low-lying land is submerged by seawater. The range of a coastal flooding is a result of the elevation of floodwater that penetrates the inland which is controlled by the topography of the coastal land exposed to flooding. Flood damage modelling was limited to local, regional or national scales. However, with the presence of climate change and an increase in the population rates, flood events have intensified and called for a global interest in finding out different methods with both spatial and temporal dynamics. The seawater can flood the land via several different paths: direct flooding, overtopping of a barrier, breaching of a barrier. Coastal flooding is largely a natural event, however human influence on the coastal environment can exacerbate coastal flooding. Extraction of water from groundwater reservoirs in the coastal zone can instigate subsidence of the land, thus increasing the risk of flooding. Engineered protection struct ...

Neva Bay
The Neva Bay (Russian: Не́вская губа́, ''Névskaya Gubá''), also known as the Gulf of Kronstadt, is the easternmost part of the Gulf of Finland between Kotlin Island and the Neva River estuary where Saint Petersburg city centre is located. It has a surface area of . The entire bay has been separated from the Gulf of Finland by the 25 km long Saint Petersburg Dam. The area of water separated by the dam is . The entire coastline is designated part of St. Petersburg rather than of Leningrad Oblast. The bay is also informally known as " the Marquis' Puddle" after Jean Baptiste, marquis de Traversay, the Russian naval minister who regarded the shallow waters of the bay as an ideal place for holding naval exercises. The Saint Petersburg Dam separates the bay from the Baltic Sea The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central Europe ...

Gulf Of Finland
The Gulf of Finland ( fi, Suomenlahti; et, Soome laht; rus, Фи́нский зали́в, r=Finskiy zaliv, p=ˈfʲinskʲɪj zɐˈlʲif; sv, Finska viken) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg in Russia to the east, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbors are located farthest in, near Saint Petersburg (including Primorsk). As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf. Proposals for a tunnel through the gulf have been made. Geography The gulf has an area of . The length (from the Hanko Peninsula to Saint Petersburg) is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eider (river)
The Eider (german: Die Eider; da, Ejderen; Latin: ''Egdor'' or ''Eidora'') is the longest river in the German state of Schleswig-Holstein. The river starts near Bordesholm and reaches the southwestern outskirts of Kiel on the shores of the Baltic Sea, but flows to the west, ending in the North Sea. The lower part of the Eider was used as part of the Eider Canal until that canal was replaced by the modern Kiel Canal. In the Early Middle Ages the river is believed to have been the border between the related Germanic tribes, the Jutes and the Angles, who along with the neighboring Saxons crossed the North Sea from this region during this period and settled in England. During the High Middle Ages the Eider was the border between the Saxons and the Danes, as reported by Adam of Bremen in 1076. For centuries it divided Denmark and the Holy Roman Empire. Today it is the border between Schleswig, Holstein and Eiderland, the northern and southern parts, respectively, of the modern ...

Eidersperrwerk Ty20060715r0012451
The Eider Barrage (german: Eidersperrwerk) is located at the mouth of the river Eider near Tönning on Germany’s North Sea coast. Its main purpose is to protect against storm surges from the North Sea. It is Germany’s largest coastal protection structure. It was also intended to contribute to economic recovery in the districts of Norderdithmarschen (today part of Dithmarschen) and Eiderstedt (today part of Nordfriesland). Celebrated as a structure of the century, it was opened on 20 March 1973. Following the North Sea flood of 1962 which swept through Tönning, consideration was given to raising the dykes along the banks of the Eider or building a storm surge barrier at its mouth. The latter was chosen and construction work began in 1967. The current conditions in the estuary caused great difficulties and the cost of construction was correspondingly high (ca. 170 million DM = ca. 87 million euros). The line of dykes in the Eider region was shortened from 60 km t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropics, tropical seas. "Cyclone" refers to their winds moving in a circle, whirl ...

Pumping Station
Pumping stations, also called pumphouses in situations such as drilled wells and drinking water, are facilities containing pumps and equipment for pumping fluids from one place to another. They are used for a variety of infrastructure systems, such as the supply of water to canals, the drainage of low-lying land, and the removal of sewage to processing sites. A pumping station is an integral part of a pumped-storage hydroelectricity installation. Canal water supply In countries with canal systems, pumping stations are also frequent. Because of the way the system of canal locks work, water is lost from the upper part of a canal each time a vessel passes through. Also, most lock gates are not watertight, so some water leaks from the higher levels of the canal to those lower down. Obviously, the water has to be replaced or eventually the upper levels of the canal would not hold enough water to be navigable. Canals are usually fed by diverting water from streams and rivers i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
