Muddy coasts can be found at all latitudes and continents, but are mostly found in tropical areas, particularly of Asia, where they settle in quiet areas and near river mouths. An example of a muddy coast is the Guyana coast in South America. This 1600 km long coast of Guyana, Surinam, French Guyana, parts of Brazil and Venezuela consists mainly of mud transported to the coast by the Orinoco and Amazon Rivers. Along large parts of the coast mangroves are found (see Sect. 2.6.6). Other examples of mud coasts can be found near the mouths of the Mississippi River (USA) and the Yellow River (China). Mud also plays an important role in parts of the coastal system of the Netherlands. The low lying parts of the Netherlands are mainly formed by sediments carried by the rivers Rhine, Meuse and Scheldt. Especially the estuarine area in the southwest (Zeeland) and the Wadden Sea are influenced by mud (see Fig. 2.34). Besides, there is a large supply from the southern North Sea and the Channel.
