3 1 0 4
Module I
Review of fundamental principles and its relative significance – (no questions to be asked). Classification of
ocean waves, Definition of wave parameters (wave length, period, Celerity). Regular and irregular waves.
Linear Wave theory (Airy’s theory)-Assumptions- Boundary Conditions, solution of Laplace equation with
Boundary Conditions - Derivation of wave surface profile, wave length, wave celerity, orbital motion of water
particles and orbital displacement of water particles in shallow water condition, transitional water condition and
deep water conditions-related problems.
Module II
Wave kinematics, pressure field under wave system, wave energy, Energy propagation (Energy flux or wave
power), group velocity in deep and shallow water conditions-related problems.
Wave Transformations- Shoaling, refraction – refraction patterns on different bed configurations- problems
considering shoaling and refraction effects, wave reflection wave diffraction, wave breaking in deep water,
transitional water and shallow water, types of breakers.
Module III
Finite amplitude theory-Stokes theory, Trochoidal theory and solitary wave theory, Region of validity of various
theories.
Wave loads on vertical walls and Caissons - Sainflou method (problems) - Brief study of Minikin Method and
Goda's method (Problems not required).
Wave measuring techniques-pressure wave gauge, Rider buoys, Wave direction measuring techniques.
