Upper South Creek Flood Study

Flood Study Final Report The Upper South Creek Catchment lies within Camden City Council’s Local Government Area. Within the defined study area (i.e. from the head waters to as far north as Bringelly Road) the South Creek catchment includes (from east to west) Bonds Creek, Kemps Creek, Rileys Creek, South Creek, Lowes Creek and Thompsons Creek. The Upper South Creek area is currently undergoing limited urban development with significantly more of the same planned for the future and as such landscapes which are currently mainly rural residential, will, over the course of ensuing years, become relatively urbanised. In order to plan development and ensure that its responsibilities regarding planning and risk management are met, Camden Council has engaged in the State Government’s Floodplain Risk Management Planning process. The first step of this process is the carrying out of a Flood Study in order to define design flood behaviour and also to create a model suitable for testing mitigation works in ensuing stages of work. As part of the Study a hydraulic model has been built. In order to establish the accuracy of the model for describing design flood behaviour it has been calibrated and validated. Results of the model calibration/validation work are presented herein, including a review of relevant previous studies and a discussion on the data collected for constructing and calibrating the hydraulic models used in the study. Note that previously Council and OEH have confirmed the suitability of the modelling system developed, on the basis of calibration/validation work presented herein. Calibration was carried out for the 1988 event which was a large event (between a 30 and 70 year ARI event based on References 1 and Reference 2, respectively) and for which 15 flood marks were available. Two smaller events (~ 10 year ARI) were used for validation purposes (1991 and 1992 events). The match between the model and the observed data for these events
