Coastal Dynamics 2009 is the sixth conference in a sequence of technical speciality conferences bringing together field and laboratory experimentalists, theoreticians and modelers conducting research on the dynamics of the coastal systems. The multidisciplinary Coastal Dynamics 2009 will be of interest to coastal engineers, coastal geologists, oceanographers, and related scientists. It is also of relevance to coastal specialists and managers, and to those interested in preserving coastal zones. In Coastal Dynamics 2009, special emphasis will be placed on the impacts of human activity on dynamic coastal processes.Contents:Real-Time Wave Prediction Using Hourly Analyzed Atmospheric GPV (T H Tom et al.)Improved MPS Methods for Wave Impact Calculations (A Khayyer & H Gotoh)Using a Particle Hybrid Method to Model Coastal Bluff Collapse During Extreme Events (J Vandamme et al.)Resonant Evolution of Long Period Waves by Periodically Fluctuating Wind Velocity (T Izumiya et al.)A Model of Wave and Current Fields Around Coastal Structures (P T Nam & M Larson)Failure Mode Against Impact and Solitary Waves of Armoured Caisson Breakwaters Protected by a Partially Failed Armour Layer (M Esteban et al.)Numerical Analysis of Harbor Oscillation in Harbors of Various Shapes (T Kakinuma et al.)Storm Surge Hindcast in Tosa Bay of Japan Using a Coupled Model of Surge, Wave and Tide (S Y Kim et al.)Alongshore Variation in Nonlinearities in Swash Hydrodynamics Over Beach Cusps (K R Bryan & G Coco)Field Measurements of Net Sediment Flux From Individual Swashes on a Sandy Beach (C E Blenkinsopp et al.)and other papersReadership: Graduates and researchers in coastal engineering, coastal geology and oceanography.
