Flood Modelling and Hazard Assessment for Extreme Events in Riverine Basins --------- Giovanni D. Musolino Crop photos to “shape”

Increasing number of extreme flood events and their impact on society lead to the need of a better assessment of flood hazard. source: www.independent.co.uk Flood Modelling is a useful tool to study and assess flood events. www.wisecdt.org

Research Aims www.wisecdt.org Refine a high resolution 1D model to predict hydrodynamics processes in river and estuarine water. Apply this model to cases study individually or coupled with a 2D model. Use results of the applications to define a guideline of which model is more suitable to be used depending by values of bed slope and roughness of the considered river. www.wisecdt.org

Research Project Details Step1 - Two versions of the refined 1D model will be applied to a series of idealized version of typical river basins. Version 1 including a Shock Capturing Algorithm (SCA) - Version 2 not including SCA www.wisecdt.org

Research Project Details Step2 - Apply the two versions of the 1D model and a 2D model (or a 1D/2D coupled model, depending by the case) to some practical cases and compare results. Two cases study will be considered: Toce river valley (Italy) and the Malpasset dam break (France). Numerical results will be compared with experimental data for both cases. General view of Toce river physical model source: http://www.impact-project.net View of Malpasset Dam www.wisecdt.org

Research Project Details Step3 - the refined 1D model will be applied to flooding in urban area. Eventually if there will be enough time, it will be added to the 1D model a sediment transport module or a water quality module (e.g. nutrient, fecal indicator, phosphate). Conclusion - Results of all the applications will provide a guideline of which of models is more suitable to be used depending by values of the bed slope and roughness. 1D? 2D? 1D/2D COUPLED? www.wisecdt.org
