  • Point features delineating observed and interpreted flood heights, derived from observations during flood events as well as flood mapping projects. The height captured is the height in metres above the AHD of flood levels reached. It shows recorded flood heights from 1870 to 2012. It is used in conjunction with historic flood extents and contours. The data is coded with date of observation (actual flood time and date) as much as possible. Note: - This data does NOT represent flood water depth. - The Flood Height Points dataset accommodate all available flood height point data, including observed flood heights until 2012. - All historical data is included with observed, interpreted and modelled flood height data for each event within the one layer. A reliability and interpretation methodology can apply to each point.

  • The Port Fairy Local Coastal Hazard Assessment (LCHA) provides information on the extent of coastal hazards and their physical impacts for the Port Fairy coastal environment. This data identifies areas that could be affected in the event of salient loss, which cannot be fully quantified with contemporary desktop engineering techniques. The areas highlighting the risk of salient loss were obtained by using the overall surrounding beach alignment, as this would likely be the natural position to which the shoreline would revert in the eventuality of salient loss.

  • The Bellarine-Corio Bay Local Coastal Hazard Assessment (LCHA) provides information on the extent of coastal hazards and their physical impacts for the Bellarine-Corio Bay coastal environment. Static (bathtub) inundation modelling was carried out to create this data layer for 1% Annual Exceedance Probability (AEP) coastal inundation under the assumption of 0.5m Sea Level Rise in 2016, for the following study areas along the coast of the Bellarine Peninsula and Greater Geelong area: Avalon; Breamlea; Connewarre Lake; Geelong Waterfront; Indented Head; Limeburners Lagoon; Newcomb; North Geelong; Portarlington; Queenscliff; Salt Lake; Sands Caravan Park; St Leonards; and Swan Bay.

  • The Port Fairy Local Coastal Hazard Assessment (LCHA) provides information on the extent of coastal hazards and their physical impacts for the Port Fairy coastal environment. This data considers setback of the present day shoreline due to coastal erosion if existing seawall (where present) was to fail. The four key components of coastal setback that are incorporated into this hazard line are: - S1, allowance for short term storm erosion (storm demand 100 year ARI); - S2, allowance for dune stability (zone of reduced foundation capacity); - S3, allowance for ongoing underlying recession; and, - S4, allowance for recession due to future sea level rise. The total design setback (S) for three planning horizons comprises: - Present day: S = S1 + S2; - 2050: S = S1 + S2 + S3(2050) + S4(2050); - 2080: S = S1 + S2 + S3(2080) + S4(2080); and - 2100: S = S1 + S2 + S3(2100) + S4(2100). Sea level rise projections utilised for the planning horizons were 0.4 m for 2050, 0.8 m for 2080 and 1.2 m for 2100 respectively. Where appropriate, the +6 m AHD contour was used as a reference as it was considered to represent the coastal alignment reasonably. The crest of the rock revetment was used as the reference contour on the southern half of East Beach. For low-lying dune systems the +2 m AHD contour was used.

  • The Port Fairy Local Coastal Hazard Assessment (LCHA) provides information on the extent of coastal hazards and their physical impacts for the Port Fairy coastal environment. This data represents the inundation extent for the Port Fairy study area. It has been derived from the combined analysis of the results of "bathtub" inundation modelling (considering astronomical tide, barometric setup and wave setup) and "dynamic coastal inundation numerical modelling" for the coastal area of the Port Fairy township (estimating combined ocean and catchment flooding). The following conditions were assumed: - 20 year Average Recurrence Interval (ARI) Riverine Boundary Condition - 100 year ARI Ocean Boundary Condition - 2100, 1.2 m Sea Level Rise - Extended dune breach (385m) next to East Beach rock revetment end Details of the assumptions made in the derivation of this information can be found in project reports on the Our Coast website: http://www.ourcoast.org.au/cb_pages/resources.php.
