Flood Modelling and Hazard Assessment for Extreme Events in Riverine Basins ---------

This research aims to refine a high-resolution 1D model for predicting flood events in river and estuarine water. The model will be applied to idealized river basins and practical cases, and the results will be compared with experimental data. The study will also explore the use of a sediment transport module and a water quality module. The findings will provide guidelines for selecting the most suitable model based on bed slope and roughness values.

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

  2. 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

  3. Research Aims • 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

  4. 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

  5. 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

  6. 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
