Abstract:

The average annual cost of flooding in Australia is $318 million per year (BTE, 2001). Some 100 flood studies, floodplain management studies and plans are currently being undertaken in Australia to seek to reduce the potential flood risk to residents and properties in flood-affected areas. Consequently, a great body of knowledge and experience in flood modelling practices has been acquired, from one-dimensional (1D) steady-state models through to two-dimensional (2D) finite element hydrodynamic models. This paper critically appraises 1D and 2D hydraulic modelling techniques based on a quantitative comparison of MIKE-11, HEC-RAS and RMA-2 modelling results for a creek system in Australia. Based on the findings of the case study, the paper provides practical guidance for modellers on the suitability of 1D and 2D modelling for common physical channel and floodplain characteristics.
