Abstract

Peel-Harvey Estuary is an ultra-shallow multi-basin estuary in which salinity varies from almost fresh in winter to hypersaline in autumn. The physical dynamics of the estuary are controlled by riverflow, low-frequency variations of ocean water level, wind forcing, evaporation, and diurnal tidal currents in the channels connecting the basins. A study of these processes is presented with examples of observational data and numerical models. A discussion is also given of the importance of physical processes to the occurrence of annual blooms of Nodularia spumigena and the cycling of phosphorus, (which is input to the estuary by riverflow), between plankton and sediments.
