Overland Flood Study area model extent (approx. 253km²)
This study covers a large proportion of the Sutherland Shire, including urban areas (excluding previously completed study areas of Gwawley, Woolooware, Bundeena, and Kurnell sub-catchments) and roads in non-urban areas (e.g., national parks, to the extent that overland flow could impact on flood emergency response).
