Dykes can be permanent earthworks or emergency constructions (often of sandbags) built hastily in a flood emergency. Also dykes were built to reclaim land from the sea. For instance, the Zuiderzee Works (North Sea Reclamation Works) in the Netherlands are an immense series of dykes built primarily to shorten the coast line and make it safer. This dyke sytem goes further to the east and north via nearly the whole German coast up to Esbjerg in Denmark. The estuaries of the flatland rivers Rhine, Elbe, Ems, Weser and EiderEider may refer to: two genera and four species of birds in the duck subfamily Merginae: Common Eider Somateria mollissima King Eider Somateria spectabilis Spectacled Eider Somateria fischeri Steller's Eider Polysticta stelleri the downy feathers from the are also protected from storm tideA storm tide is a tide with a high flood period caused by a storm. Storm tides can be a severe danger to the coast and the people living along the coast. The water level can rise to more than 5 m (17 ft) above the normal tide. Compare to storm surge.s by dykes, which can be more than 9 mFor other uses of "metre" and "meter", see Metre (disambiguation). The metre is the basic unit of length in the International System of Units (SI: Systeme International d'Unites). It is defined as the length of the path travelled by light in absolute vacu high.
The Netherlands also has some 13,000 km of Boezem dykes, secondary dykes typically of 1.5 - 4 m high, and essential to the continued drainage of reclaimed land. The dykes are typically merely simple earth embankments, though 20% are constructed from peatLewis, Scotland Peat is an accumulation of partially decayed vegetable matter. Peat forms in wetlands or peatlands variously called bogs moors muskegs mires and fens''.

The city of Richmond, British ColumbiaRichmond is an incorporated city on the Pacific coast of British Columbia, Canada. It is located at Lat 49°11' N and Lon 123°8' W. Richmond forms part of the Greater Vancouver Regional District. Its neighbouring municipalities include Vancouver and Burnab in Canada is an island of 129.666 km2 at the delta of the Fraser River protected by a system of dykes. The first dykes were created by individual farmers in 1861 to reclaim land. Pumps are still used to this day to keep water out, and there are still uncovered ditches throughout much of Richmond. Many of the ditches are being replaced with pipes with sidewalks on top.
