Description 1-4
Littoral currents were measured by injecting rhodamine 'B' into the surf zone at distances of about 200 m along the beach (from Sinquerim to Baga) during January to September 1972. These currents were associated with the mass transport due to breaking waves and are directed towards north during a greater part of the fair weather season. During premonsoon and monsoon, months the littoral currents were northward in some places and southward in other places. Littoral current velocities, which generally depend on the breaker heights, angle of incidence of wave orthogonals to the shore, shoreline configuration, the nearshore bottom topography and the rise and fall of water level due to tides, were found to be higher during monsoon as compared to fair weather season. Rip currents along certain parts of the beach appear to be due to the convergence and divergence of wave energies. The area where rip currents were persistently observed in most of the surveys was demarcated as dangerous to bathers. The changes in current regimes were reflected in the patterns of sediment distribution and sediment transport.
