| Abstract | The Vembanad Lake, India's largest estuarine system is influenced by monsoonal changes and coastal dynamics. Examining estuary surface currents during tidal phase changes is beneficial, but altimeters face data reception issues near shorelines. A cost-effective surface drifter based on a Lagrangian technique has been developed to study the circulation and tidal currents in the Vembanad estuarine system. This drifter is equipped with GPS (Global Positioning System) module, GPRS (General Packet Radio Service) module and other electronic components that allow its real time tracking and helps to study the current patterns within the estuarine region by analysing the GPS location data of drifter recorded at regular intervals. A comparison of the current flow patterns derived from the designed surface drifter and an in-situ current meter was conducted and shows a good match between the two measurements. |
