This paper presents a case study of the modelling of sea level rise in flood studies, following the directive of the Victorian Coastal Strategy in 2008 to account for sea level rise of at least 0.8 m by 2100 for planning purposes. Sea level rise of at least 0.8 m must
now be included in flood studies for design flood mapping and for the delineation of Land Subject to Inundation and Floodway planning overlays.

This study focuses on modelling undertaken for the Port Fairy Regional Flood Study. The effect of the inclusion of sea level rise on design flood extent and levels is investigated. The balance between flood risks posed by storm surge inundation and riverine flooding under a scenario of sea level rise is also explored. We also present a method of accounting for dynamic ocean water levels in estuarine flood modelling studies.
