The evolution of coastal sand dunes

Scottish Geographical Magazine, 1972
Abstract : Approximately 20 per cent of the coastline of the Highlands (Land lying West and North of the Highland Boundary Fault) excluding islands, is fringed by sand accumulations in the form of dunes, links or machair. Except where sea walls and promenades protect their seaward edge, dunes are intimately linked to beaches, the margin between dune ...

Reddening of tropical coastal dune sands

Geological Society, London, Special Publications, 1983
Summary This paper describes the pedological processes, including that of reddening, in latosol formation in dune sands on humid tropical coastlines. A time-scale is established for these processes in South-east India, Sri Lanka and the Natal Province of the Republic of South Africa.

Coastal sand dunes as geomorphological systems

Proceedings of the Royal Society of Edinburgh. Section B. Biological Sciences, 1989
SynopsisThe importance of aeolian deposition is clearly shown by the size and bulk of coastal dunes. Sand dunes occur where there is a large supply of sand, a wind to move it, and a place in which it can accumulate. A dune classification is presented which takes into account the origin, internal geometry and surface geomorphology of coastal dunes ...

Coastal sand dunes as biological systems

Proceedings of the Royal Society of Edinburgh. Section B. Biological Sciences, 1989
SynopsisWith the gradation of intensities of environmental factors from the strand-line to stable inland areas, coastal dunes show many ecological phenomena especially clearly. These are reviewed broadly, with some emphasis on topics on which important advances are being made.

Shifting sands? Coastal protection by sand banks, beaches and dunes

Coastal Engineering, 2014
Abstract In a closely integrated system, (sub-) littoral sandy sediments, sandy beaches, and sand dunes offer natural coastal protection for a host of environmentally and economically important areas and activities inland. Flooding and coastal erosion pose a serious threat to these environments, a situation likely to be exacerbated by factors ...

Recent Coastal Dune Development: Effects of Sand Nourishments

Journal of Coastal Research, 2012
Abstract BAKKER,M.A.J.; VANHETEREN, S.; VONHOGEN, L.M.; VAN DER SPEK, A.J.F., and VAN DER VALK, L., 2012. Recent coastal dune development: effects of sand nourishments. Much of the Dutch coast has been subject to structural erosion. From 1990 onward, sand nourishments have been used under a government policy of dynamic preservation.

Spider Associations in Coastal Sand Dunes

Oikos, 1973
An investigation of the dune-living spiders was made during 1960-1962 in a coastal sand dune area of 40 ha at Sandhammaren, Province SkAne, Sweden. Eleven subdivisions were recognized for a vegetational survey; 821 samples from areas of 1 m2 each collected.

Mechanism of Sand Movement on Coastal Dunes

Journal of the Waterways and Harbors Division, 1966
Sand supplied to a coast by streams, cliff erosion, and other sources generally is moved in one direction along the shoreline as littoral drift under the action of the prevailing wave conditions in the area. When this drift encounters a partial obstruction, such as a prominent natural headland or a major engineering structure, a condition is realized ...
