Water Technology in conjunction with Driscoll Engineering, undertook a drainage investigation for Hindmarsh Shire Council following flash flooding in the Dimboola Township in January 2011. A 1D/2D hydraulic TUFLOW model was developed for the Dimboola study area which is approximately 330 m north-west of Melbourne. A hydrological model using RORB was developed for the study area in conjunction with the Rain-on-Grid inputs for the hydraulic TUFLOW model. Several stormwater mitigation options were investigated for the Dimboola Study area, with the flood and cost benefits for each scenario investigated. Ultimately a desirable drainage solution which significantly reduced the flooding risk and also created an important community asset was developed through the study.
