Coastal regions are well known for their dynamic flow and they are influenced by water current along the shore, and especially, port regions highly depend on physical oceanographic parameters. The present investigation is aimed to record the field observations and validation of southwest monsoon current pattern at Ennore, Chennai using bottom tracking profilers of Acoustic Doppler Profiler (ADP) and Recording Current Meter (RCM). The results clearly indicated that south side of Nettukuppam recorded the average current speed 50.64 cm/s. On the other hand, north side of Kattupalli recorded the average current speed 15.99 cm/s. This variation could be the effect of bathymetry and ship movements-induced water current at Ennore. South side of the port depth varied up to 13 m, but on the north side of the port, there is only a 6 m variation, which may highly influence the changes in the current pattern. On observation part, from the 5m depth data that was examined, ADP vs RCM clearly indicated the same current movement towards north direction. RCM provides a more consistent result with the ADP high-performance 3-axis (3D) water current profiler. In the present study, we observed and analyzed directional measurements obtained from ADP and RCM. However, future works may evaluate and compare meso-scale and sub-meso-scale processes using the ADP and RCM data, which will provide much more significant information.
