2. Increasing number of extreme flood events and their impact on society lead to the need of a better assessment of flood hazard.

Flood Modelling is a useful tool to study and assess flood events.

3. 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.

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

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.

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.
