Description: Layer combines all scenarios for all storm surge affected areas along the Otago coastline, investigated in the storm surge modelling study carried out in 2008. In effect, it shows the maximum land area extent affected by Storm surge considering 4 main return period (20,50,100 and 500 year events), and sea level rise scenarios (e.g. MHWS, MHWS + 0.3 m and MHWS + 0.5 m). Additionally, the layer 'Storm surge potential inundation 50 cm' is also incorporated to ensure coverage of all areas.
