Tamar sea level data March-August 2018

Created 24/06/2025

Updated 24/06/2025

Water level heights were measured every 5 minutes at five station locations in the 70km length Tamar estuary, Tasmania, for six months. Pressure loggers deployed in the water recorded total pressure and the inverse barometer effect was accounted for by two additional pressure loggers deployed above ground within 15km of a station. The data include barometric pressure, water temperature, and water level relative to Australian Height Datum (AHD83). The data captures tidal amplification and asymmetry between ebb and flood tides in the estuary for the purpose of a research project completed in 2018 by Karen Palmer. Based on the Tamar estuary model created for NRM North by BMT WBM Pty Ltd using TUFLOW FV (with permission), a new hydrodynamic model was created and calibrated with observed water levels. Different scenarios of sea level rise and bathymetry change were then simulated to model the effects on tidal amplitude and phase.
