Duck Creek Flood Study

In April 2010 we were commissioned by Wollongong City Council to complete survey along Duck Creek and its tributaries in Yallah, NSW. The purpose of the survey was to facilitate a flood study of the Duck Creek Catchment, which was undertaken by BMT WBM's Newcastle office. The study itself is a precursor for any future development proposed for the Yallah/Calderwood Precinct and indeed to assist those currently operating working farms within the vicinity of the catchment.

The scope of the brief required the application of a varied range of measurement techniques to collect data including GPS, Cadastral and Hydrogrpahical. Further, we were required to accurately represent existing structures such as bridges and drainage culverts to ensure accuracies in flood modelling were achieved.

Successful delivery of the project hinged on two key aspects. Firstly, the delivery of drawings that depicted cross sectional profiles of the creek bed and structures prepared in conjunction with photography allowed BMT WBM to model the catchment based on a number of storm events. Secondly, the successful integration of council's GIS and aerial photography with our GPS control network ensured that our results could easily be re-intergrated back into council's system.
