Structural design by the use of formulae and model testsThe effect of manmade activities is primarily local but can extend far away from the location of intervention. This underlines the importance of establishing coastal zone management plans covering large stretches of coastlines.In recent years, interest in Low Crested Structures (coastal defense structures with a low-crest) has been growing together with awareness of the sensitivity to environmental impacts produced by coastal defenses.The relation between wave climate, beach erosion, beach defence means, habitat changes and beach value, which clearly exists based on EC researchCoastal engineeringEnvironmental aspectsHydraulic structuresDesign and constructionCoastal engineeringEnvironmental aspects.Hydraulic structuresDesign and construction.624.1771627/.58 22627.58Burcharth H.
