ABSTRACT: Inconsistencies between
datasets are examined with reference to flood tidal elevations in the Tamar
River estuary, Tasmania Australia. Errors in a 30-year-old commonly cited
dataset have been perpetuated in subsequent publications and datasets, and a
clarification is herein provided. Elevation of the flood tidal wave as it
propagates the estuary is evident in mean tide level and mean sea level,
although the analysis is compromised by the temporal differences of the
datasets. As sea levels rise due to global warming, the importance of accurate on-going
sea level data in any estuary will become more acute.
