Offshore Aggregate Dredging and Coastal Erosion

Yet a further paper has come to light on coastal erosion brought about by Offshore Aggregate Dredging in a paper entitled:
EFFECTS OF MARINE SAND EXPLOITATION ON COASTAL EROSION AND DEVELOPMENT OF RATIONAL SAND PRODUCTION CRITERIA written by Emre N. Otay, Paul A. Work and Osman S. Börekçi

It tells how such mining yields an inexpensive source of sand for construction or industrial uses. how it may modify nearshore wave conditions, create erosion and deposition rates, impact the sedimental drift and alter benthic habitats and nearshore circulation.

The goals of the project described in the proposal are to quantify the influences of sand mining on nearshore waves and currents, assess the magnitude of any mining-related erosion, and establish guidelines for acceptable mining rates and locations. The conclusions are based on numerical model results, but with validation of some aspects of the modelling via field data, and how although the findings are site specific, the methodology could be applied at any coastal site that features primarily non-cohesive sediments.

It shows how regardless of the final destination of marine sand, topographic changes caused by underwater dredge holes have immediate effects on nearshore waves and currents and that these hydrodynamic changes can rapidly lead to local perturbations in the ambient littoral transport patterns and eventually changes in the shoreline morphologymorphology The science of form. In biological terms, it is the area of knowledge which deals with the form of plants and animals. Hence coastal morphologists — (sometimes referred to as coastal geomorphologists): those espousing or dealing with coastal geomorphology, in our treatise the changes of our coastline..
