2. Thames Flood Barrier:
The Thames Flood Barrier prevents the floodplain of most of Greater London from being flooded by exceptionally high tides and storm surges moving up from the North Sea. It has been operational since 1982. When needed, it is closed (raised) during high tide; at low tide it can be opened to restore the river's flow towards the sea. Built approximately 3 km (1.9 mi) due east of the Isle of Dogs, its northern bank is in Silvertown in the London Borough of Newham and its southern bank is in the New Charlton area of the Royal Borough of Greenwich. The report of Sir Hermann Bondi on the North Sea flood of 1953 affecting parts of the Thames Estuary and parts of London was a big factor in the planning of the barrier. More details

4. Afsluitdijk Dam:
The Afsluitdijk is a major causeway in the Netherlands, constructed between 1927 and 1932 and running from Den Oever on Wieringen in North Holland province, to the village of Zurich in Friesland province, over a length of 32 kilometres (20 mi) and a width of 90 metres (300 ft), at an initial height of 7.25 metres (23.8 ft) above sea level. It is a fundamental part of the larger Zuiderzee Works, damming off the Zuiderzee, a salt water inlet of the North Sea, and turning it into the fresh water lake of the IJsselmeer. The Afsluitdijk was the initial demonstration site for a 130 km/h (81 mph) speed limit in the Netherlands. More details
5. Levees:
A levee is an elongated naturally occurring ridge or artificially constructed fill or wall, which regulates water levels. It is usually earthen and often parallel to the course of a river in its floodplain or along low-lying coastlines. The main purpose of artificial levees is to prevent flooding of the adjoining countryside and to slow natural course changes in a waterway to provide reliable shipping lanes for maritime commerce over time; they also confine the flow of the river, resulting in higher and faster water flow. Levees can be mainly found along the sea, where dunes are not strong enough, along rivers for protection against high-floods, along lakes or along polders. Furthermore, levees have been built for the purpose of empoldering, or as a boundary for an inundation area. More details

7. St. Petersburg Dam:
The Saint Petersburg Flood Prevention Facility Complex (unofficially the Saint Petersburg Dam), is a 25 km (16 mi) complex of dams for flood control near Saint Petersburg, Russia. The dam extends from Lomonosov northward to Kotlin Island (and the city of Kronstadt), then turns east toward Cape Lisiy Nos near Sestroretsk. The complex is intended to protect Saint Petersburg from storm surges by separating the Neva Bay from the rest of the Gulf of Finland. Historically, the storm surges from the gulf had caused over 300 floods in the city, several of which had a massive devastating effect. The dam has the capability to protect the city from water rising up to 5 m (16 ft). More details

8. The Hurricane Barrier:
Beginning in 1958, the New Bedford Harbor Hurricane Barrier was built from a point about one hundred metres north of Fort Phoenix, in Fairhaven, to Gifford Street on the New Bedford coast. The 20-foot high barrier continues onto land, where three large doors allow street traffic to pass through during calm seas. The longer segment continues along the New Bedford coast to just before Frederick Street. A discontiguous segment protects the top of Clark's Cove in New Bedford, roughly to the Dartmouth border. The barrier consists of an arc of riprap and fill, approximately three kilometres long, surmounted by a service road. More details

9. Barking Creek:
Barking Creek joins the River Roding to the River Thames. It is fully tidal up to the Barking Barrage, which impounds a minimum water level through Barking. In the 1850s, the creek was home to England's largest fishing fleet and a Victorian icehouse – where the fish were landed and stored prior to being transferred to London's fish markets. Barking Creek contains a small number of house boats, and the former village of Creekmouth is nearby. The Barking Creek Barrier is a tidal flood barrier was constructed in the 1980s as part of the Thames flood defence system, opening in 1983. Like all of the subsidiary gates, it is normally closed before, and opened after, the main Thames Barrier. More details
