The applications of geomorphology surveys in various aspects of the land for numerous specific needs of mankind will contribute substantially in development. Geomorphoogical processes occur due to the agents of moving water, ice, wind and waves. The modifications will depend not only on climate, but also on the nature of materials, the form, and the time period. Deflation, soil erosion by the wind sand seas, reactivation of fossil sand seas, sand encroachment, desertification, salinity, flash floods, debris fans, mudflows. Sea floods, tsunami, cliff erosion, slope instability, beach destruction, deposition - in harbours, spit development.

Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves , currents , tides , wind-driven water, waterborne ice, or other impacts of storms. On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion. Softer areas become eroded much faster than harder ones, which typically result in landforms such as tunnels , bridges , columns , and pillars. Over time the coast generally evens out. The softer areas fill up with sediment eroded from hard areas, and rock formations are eroded away.

Coastal landforms , any of the relief features present along any coast , the result of a combination of processes, sediments, and the geology of the coast itself. The coastal environment of the world is made up of a wide variety of landforms manifested in a spectrum of sizes and shapes ranging from gently sloping beaches to high cliffs, yet coastal landforms are best considered in two broad categories: erosional and depositional. In fact, the overall nature of any coast may be described in terms of one or the other of these categories. It should be noted, however, that each of the two major landform types may occur on any given reach of coast. The landforms that develop and persist along the coast are the result of a combination of processes acting upon the sediments and rocks present in the coastal zone. The most prominent of these processes involves waves and the currents that they generate, along with tides. Other factors that significantly affect coastal morphology are climate and gravity.

History of Coastal Geomorphology

Journal of Coastal Research 1 November ; 22 6 : — Masselink and M. Hughes, The book is organised into 11 chapters: the first five cover process and context, the second five focus on specific types of coastal environment, and the final chapter provides a glimpse of coastal management. From the outset, there is a distinct succinctness to the writing style in this book, no doubt borne out of the need to systematically progress through the discipline in a concise volume.

Written for undergraduate students studying coastal geomorphology, this is the complete guide to the processes at work on our coastlines and the features we see in coastal systems across the world. Accessible to students from a range of disciplines, the quantitative approach of this book helps to build a solid understanding of wave and current processes that shape coastlines.

    The coast has been of primary concern to man since he first set foot upon it and will undoubtedly continue to be so long into the future.

    We would also like to thank Nathalie Carcaud for her picture of the Val de Loire, which allowed us to complete the illustration, as well as Monique Fort, who accepted to read the first version of this editorial.
