College, Orth and Werrington Creeks Catchment Overland Flow Flood Study

The College, Orth and Werrington Creeks Catchment Overland Flow Flood Study was prepared for Penrith City Council to identify main stream and overland flood behaviour across the catchment. The catchment covers an area of 12 square kilometres and includes the suburbs of Werrington, Werrington County, Cambridge Park, Kingswood, Caddens and parts of Orchard Hills. During periods of heavy rainfall across the catchment, there is potential for the capacity of the stormwater system to be exceeded. In such circumstances, the excess water travels overland, potentially leading to inundation of roadways and properties. There is also potential for water to overtop the banks of the creek network and inundate the adjoining floodplain.

A computer flood model of the College, Orth & Werrington Creeks catchment was developed using the TUFLOW software as part of the study. The model was developed to include a representation of all features that will influence the movement of floodwaters across the catchment. This includes all stormwater pits and pipes, bridges, culverts, detention basins, buildings and fences. The topography across the catchment was defined in the model based upon a digital elevation model derived from aerial survey collected in 2011.
