Strandflat

The strandflat is a rim of gently sloping bedrock plain in front of higher land or coastal mountains (Klemsdal 1982, 1985). The plain has a very irregular terrain with small differences of height. Most of the bedrock plain is covered with a thin mantle of loose material; only locally does the loose material have forms of its own. The gently sloping, undulating, flat produces, when meeting the sea, an uneven coastline with numerous bays, coves, inlets, islands, islets and skerries, all characteristics features of the skerry zone. The gradient of the supramarine zone varies between 5 and 25 m per km. The topography of the supramarine and skerry zones continues into the sea. At a depth between 30 and 60 m a break in the slope occurs and steeper slopes lead down to the paleic, old forms of the bankflats constituting part of the continental shelf. Inland, the strandflat terminates at heights between 30 and 80 m, where in most places a steep slope leads up to higher land, though in some...
