Approach and Outcomes
Toowoomba Regional Council had recently undertaken flood studies of the region for which WMS had played a crucial role. For Dry Creek, hydrologic and hydraulic models developed for these studies were utilised with appropriate upgrades including a new model topography and recalibration. For Gowrie Creek, a new 2D flood model was developed. Within the Nexus Infrastructure project team, WMS worked to test multiple bridge and culvert arrangements to minimise flood impacts and scour potential. The primary outcome of the project was an impact assessment of the crossings for Dry Creek and Gowrie Creek.
