Flood-tide delta morphological change at the Gippsland lakes artificial entrance, Australia (1889-2009)

Auteur(s) et Affiliation(s)



Description :
Analysis of historical survey and navigation charts, aerial imagery, and digital hydro-data (representing a time-series of 1889-2009) allows the morphological evolution of a flood-tide delta at the artificial entrance to the Gippsland Lakes (Victoria, Australia) to be visualised and quantified. The analysis shows that the flood-tide delta growth corresponds with a progressive diminution of Gippsland Lakes catchment river discharge volumes, and dampening of flow variability, due to both regional precipitation pattern changes and changes in catchment water resource allocation. The impacts of the future climate change predictions for the Gippsland Lakes catchment and coastal area are discussed regarding future sediment management strategies for navigation maintenance.
