Minnegang Creek Flood Study Report - Wollongong City Council

5.12.4 Overland flow pathsAs discussed in Section 6.2, the capacity of the piped system is inadequate in manylocations. In these locations flow in excess of the pipe capacity travels along overlandflow paths until the next inlet to the piped drainage system is reached. Flow then eitherenters the system, if there is sufficient capacity at this location or will continueoverland.These overland flow paths were included in the MIKE 11 model in most areas of thecatchment. Roads in the catchment are likely to act as other flow paths. In theselocations, flow in excess of the capacity of the piped system will be contained withinthe kerb and gutters along the road. These flows will continue within the road until thelow point of the road is reached. Flows will then overtop the kerb and follow overlandflow paths between properties or along drainage easements through the catchment toMinnegang Creek.SV8507-D0-001 Rev 2 5-3518/10/02
