In late June 1998, a damaging flood event occurred at Lakes Entrance (Victoria, Australia), which was partly due to retardation of floodwater flow through the Gippsland Lakes artificial entrance by the level of flood-tide delta sediment accretion in the Entrance and Reeves Channels. Analyses of digitised three-dimensional hydrographic datasets allowed the extent of pre and post-flood event bathymetric change to be visualised and also quantified.
