Short summary
Restoration of intertidal wetlands such as mangroves and saltmarshes requires accurate local data on tidal flooding and current velocities. We present the application of a low-cost underwater float equipped with an acceleration data logger, the Mini Buoy, to monitor inundation and tidal currents in intertidal environments. We demonstrate how this tool can be directly applied in hydrological site suitability assessments prior to mangrove restoration in tropical SE Asia.
