Abstract/Summary Tsunami inundation and overtopping of coastal barriers pose potentially serious risk to large regions of the Australian coastline. Validation and testing of tsunami models is an important process in developing tools to mange this risk and is usually performed in small scale hydraulic model testing. This paper presents the results from testing the Geoscience Australia tsunami inundation model, ANUGA, in laboratory experiments at the University of Queensland. Tsunami type run-up flows were generated in tilting dam-break flume, simulating the run-up and overtopping of the leading edge of a tsunami wave. The experimental data include run-up over smooth and rough beds, water depths at different cross-shore positions, flow velocities and mobile bed sediment transport measurements. The ANUGA model was setup to replicate the dam-break boundary conditions and numerical simulations were performed covering the range of experimental conditions. Numerical model results and measurements are in excellent agreement in terms of predicted run-up elevations, and both flow depths and flow velocities are also accurately estimated Measured and modelled sediment transport rates show excellent correlation, and enable sediment transport coefficients to be accurately determined for these very fast and shallow water dry/wet flows. In conjunction, the experiments and modelling provide a tool to develop models for the overwash of water and sediment across coastal barriers.
