509-515Wave energy distribution along Gangavaram, east coast of India has been carried out for the
predominant waves representing southwest monsoon (June-September), northeast
monsoon (October-February) and storm period (March-May and October) using a
wave refraction model. Model computes refraction coefficient, shoaling
coefficient, breaker heights and breaker energies along the coast. During all
seasons, higher wave energy pattern is observed in the region to the south of
the port but towards north, complex wave conditions exist due to rocky
headlands and promontories and as a result wave breaking transpires at deeper
depths. Low wave energy conditions are observed very near to north breakwater
during all the seasons and even during storms. During storm conditions wave
energies amplify along the coast. South breakwater of the port is under the
region of convergence during southwest monsoon and for the storms approaching
in south-south-east direction. Numerical wave refraction studies facilitate the
coastal engineers and scientists to understand the coastal processes
