Description Using the British admirality bathymetric charts off the west coast of India and employing the graphical method of constructing wave refraction diagrams, an attempt is made to study behaviour of the short-period waves (4, 5 and 6 seconds) which are found to affect the coast generally in the neighbourhood of Cochin Port (Kerala, India) entrance Nineteen stations, at intervals of roughly one mile, are chosen around the three fathom line in this area Considering a probable field of approach of deep-water waves, limited to a cone of 90 degrees, five directions of approach are chosen at intervals of 22 1/2 degrees in the range of 202 1/2 degrees to 292 1/2 degrees Refraction diagrams are prepared for these directionsand periods, and from these, the refraction functions and directional parameters are evaluated for each station The possible directions of flow of long-shore current and the areas vulnerable to erosion and sedimentation are investigated.
