SUMMARY:Deterministic simulation of wave transformation in the coastal zone
  and estimation of wave overtopping of coastal structures
DESCRIPTION:Abstract: Protecting urban and industrial areas located near t
 he coast from the risk of wave-induced flooding during storms is a major c
 hallenge\, particularly for EDF\, which operates several nuclear power sta
 tions on the coast or in estuaries. For that purpose\, coastal defences su
 ch as breakwaters are built and designed based on admissible average wave 
 overtopping discharges over the protection in given storm conditions. The 
 goal of my PhD thesis* was to develop a phase-resolving numerical model ab
 le to simulate nearshore wave propagation from offshore to the coast\, as 
 well as their interaction with coastal protections\, in particular wave ru
 n-up and overtopping processes. The developed model\, named galatea_GN\, s
 olves the depth-averaged enhanced Serre-Green-Naghdi (eSGN) equations of B
 onneton et al. (2011)\, both in one and two horizontal dimensions. Depth-i
 nduced wave breaking is modelled with an eddy-viscosity approach which rel
 ies on a one-equation turbulence model for the turbulent kinetic energy. S
 pecial attention was devoted to developing a numerical implementation stra
 tegy and using accurate and efficient numerical methods\, able to capture 
 dry fronts which repeatedly occur during run-up and overtopping. The numer
 ical model will be presented\, as well as several experimental validation 
 cases\, and its application to reproduce laboratory experiments of irregul
 ar wave overtopping\, both in one and two horizontal dimensions.\n\n* Coul

  of EDF\, the French national electricity producer\, and the Saint-Venant 
 Hydraulics Laboratory (LHSV)\, in Chatou\, Paris area. I developed a phase
 -resolving numerical model for the simulation of nearshore wave propagatio
 n and wave overtopping of coastal protections. I defended my PhD thesis la
 st November\, and I now work at EDF R&D as a research engineer. I contribu
 te to the MOISE-2 project\, whose aim is to evaluate and strengthen the re
 silience of existing and future nuclear power plants against external coas
 tal and fluvial flooding hazards. I am also involved in the development of
  the openTELEMAC modelling system\, developed at EDF.
