Presentation transcript:

Prelude Fields Related to Wave Mechanics Ocean Engineering: Ship, water borne transport, offshore structures (platforms). Navy: Military activity, amphibious operation, WW II Allies landing. Coastal Engineering: Harbor and ports, dredging, coastal structures, beach erosion, sediment transport. Oceanography: Ocean environment, atmosphere, fishing, oil spilling, mixing, pollutant transport. Environmental Eng.: Capping contaminated dredged material. Diffusion and dispersion of toxic material in ocean and costal water.

Contents Review: Fundamentals of Linear wave Theory and Basic Nonlinear Wave Theory Theory: a) Weakly Nonlinear Wave Theory. Perturbation Methods: 1) Mode Coupling Method (MCM), 2) Phase Modulation Method (PMM), 3) others. b) Finite Amplitude Wave Theory Physics a) Weak or Resonant Wave-Wave Interactions. Wave Instability, energy transfer and WAM. b) Strong Wave-Wave Interaction. Bound Wave, Wave Modulation and Second-order and Third-order Solutions.

Application: 1) Hybrid Wave Models: Decomposition and Prediction. 2) Scientific and Engineering Applications. Wave Kinematics, pressure and elevation. Wave data Analyses. Extension: Linear theory  Weakly non-linear theory  Finite amplitude wave theory. Periodic Wave  Narrow banded wave  Broad-banded wave theory.
