The study area drains an area of about 30 km² to Lake Macquarie. Major natural channels within the contributing catchments include Karignan Creek, Tiembula Creek and Bonny Boy Gully. The study area also consists of a series of constructed drainage channels, a stormwater system with sub-surface piped drainage, and naturally formed overland flowpaths.</SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>Due to the nature and complexity of the hydraulic modelling, it was deemed appropriate to filter the design flood extents, such that only regions of flood depths greater than 0.15 m were included.</SPAN></SPAN></P><P><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P><SPAN /></P></DIV></DIV></DIV> |
