Prerequisites:

None 
Target skills and knowledge:

Coastal flooding is expected to be one of the most important problems in the next 2030 years. It is expected that new jobs will arise to produce risk mapping, design of mitigation works, insurance and legal issues, etc
The course aims at providing the student with the basic knowledge in the field of coastal flooding hazard assessment, and the proper skills in order to keep into account safety, costeffectiveness and environmental criteria. To the purpose, the course will include lectures, practical works, one seminar and a technical tour. 
Examination methods:

The final evaluation will be carried out as follows:
1) The student will deliver  better if a few days in advance  a small document containing the 3 numerical exercises developed in class (completed by each group, formed by 34 persons).
2) Then, the student will answer 2 questions (the complete list of possible questions will be given during the course). He will have 10 minutes to answer each question. 
Assessment criteria:

Evaluation will be based on the:
quality of exercises (50%)
oral examination (50%): excellent answers should be complete, to the point and correct. During the oral examination, the student typically writes on a spear paper equations, graphs or schemes. 
Course unit contents:

1. Introduction (4h)
Motivations and objectives
What is coastal flooding hazard
The drivers: the causes of coastal flooding
Effect of “Climate change” or “Global Warming” on sea level rise
Mitigation measures: examples
2. Geophysical fluid dynamics (6h)
Description of the dynamics of the atmosphere and of the oceans and main drivers for coastal flooding.
Domain Equations
Geostrophic wind, winds at the ocean, wind distribution, friction
Tide: physics. The Equilibrium Theory of Tides. The Lagrangian Tidal Equations..
Exercise in Matlab (application of LTE)
3. The waves (10 h)
Bernoulli Theorem, Linear wave theory, wave kinematic
Irregular nature of the waves, Rayleigh distribution, definition of significant wave
Fourier analysis and wave spectrum.
Exercise in Matlab (Periodogram. spectum, filter)
Wave energy, wave transformation processes (shoaling, refraction, diffraction, breaking, runup)
Exercise in Matlab (wave transformation on a real profile)
Shallow water eq. and coastal hydrodynamics, setup, longshore currents. Surge
4. Sediment transport (4h)
Depth of closure concept. Equilibrium profile. Brunn rule.
Longshore sediment transport. Crossshore sediment transport. Aeolian transport
Dean diffusive model.
Exercise in Matlab (diffusive model, both finite elements & finite differences)
5. Extreme wave statistics (2h)
Estimation of extreme marine events. Joint statistics of tide and waves
Exercise in Matlab (maximum likelihood fit of 3 parameter distribution to a series of hindcasted data)
6. Reliability analysis (4h)
Failure mechanism for coastal flooding.
Exercise in Matlab (level II method, 1D case)
7. Evaluation of the flooding hazard (4h)
How to produce a Coastal flooding hazard map.
Example in GIS.
Mapping expected value and economic costs related to flooding.
Evaluation of Coastal Flooding Index.
Interactions with river discharge and urban flooding (Tidal inlet)
8. Mitigation measures (4h)
Methods to evaluate the effectiveness of proposed adaptation measures (setback strategy, managed realignment, dike, nourishment, water extraction control,…)
9. Flood management tools (2h)
Examples of DSS for coastal flooding management
10. Modeling coastal flood (2h)
Description of existing models (free operational & commercial)
Exercises (6h)
The student in group will select and develop3 exercises described above and produce a summary report with the exercise objectives, input and output. 
Planned learning activities and teaching methods:

The course is composed of theoretical lectures, a seminar, a technical visit and numerical exercises (15 h).
Lectures are given with the aid of powerpoint
The short seminar (presented by a visiting professor) and the technical visit will be organized during the course, also based on the interest of the students
 3 exercises will be carried out in class (with the aid of Matlab or similar) selected by the students, based on a list of 7.
