Integrated report on design of innovative coastal structures and best practices for coastal defence. Results from numerical, experimental and prototype testing.

General aim of WP2 was the development of innovative "climate proof” defence methods for mitigation of coastal flooding and erosion hazards in the context of increasing storminess and sea level rise (scenarios defined by WP 1). More specific objectives were: - to estimate wave reduction at the shoreline induced by barriers for wave energy conversion, - to quantify wave dissipation and related morphological effects induced by multi‐purpose low impact structures such as artificial reefs and bottom vegetation, - to analyse performance of different cover layers for overtopping resistant dikes, - to improve management of sediment stocks, knowledge of the impact of sandy borrow areas, technologies for nourishment and dredging, in the perspective of optimised beach maintenance plans. This report presents a synthesis of the prototype observations, physical and numerical modelling performed within WP 2 by all the partners.
