Abstract
CAE is leaving for UPC, in Barcelona, to conduct his own funded research from EU (Marie-Curie Action) on "amending the Design criteria of URban defences in LECZs through Composite-modelling of WAVE overtopping under climate change scenarios" (DURCWAVE). The project will start in March 2019 and last 2 years.

This Marie-Curie project is relevant for our subgroup KUST and aK, beacause deals with coastal defenses and safety assessment in urbanized coastal areas, such as, for example, the Flemish coastal towns. The contents of CAE project are summarized as follows:

The growth in coastal zone population increases the exposure of large numbers of people and assets to hazards related to
climate change. Sea level rise and increased storminess represent major threats to coastal defences preventing the
inundation of the hinterlands. This is true especially in low elevation coastal zones (LECZs). Understanding the mechanisms
that govern the interaction between overtopping waves and coastal defences to changing climate conditions is of outmost
importance to amend the current design criteria of coastal defences. The present project, named “DURCWAVE” (amending
the Design criteria of Urban defences in LECZs through Composite-modelling of WAVE overtopping under climate change
scenarios), aims to identify new design criteria for wave action by modelling wave overtopping and post-overtopping
processes of urban defences (storm walls, stilling wave basins, buildings along coastal boulevards). To reach these
objectives the project will implement a composite-modelling approach, consisting of both physical and numerical modelling.
Physical model tests will be carried out in two different wave flume facilities at the host organization (UPC), meanwhile the
numerical modelling will be performed through the secondment at the partner organization (Uvigo). The mesh-free
DualSPHysics model will be used for the scope. The EPR data-driven technique will be used to find new correlations
between wave impacts and overtopping flows. The Action will provide a methodology to help decision-makers to estimate
the vulnerability of coastal zones to climate change, by assess the threats for sea frontages and buildings on the coastline.
The project outcomes will trace the path at National and European levels for further extensions from urban defences in
LECZs to all kind of coastal defences. Furthermore, a unique numerical model technique to simulate post-overtopping
processes and estimate wave loadings on coastal defences will be release open-source for public use.​

The role of FHR will be external advisor for the CAE Marie-Curie project. FHR will benefit from the knowledge exchange in terms of overtopping design criteria and coastal management policy and from data sharing with UPC and CAE (including experimemental and numerical model results). Occasional meetings will be held in UPC, Uvigo and/or FHR. Dissemination and knoledge exchange will be fostered by these meetings. Moreover, the collaboration and participation in supervising/follow-up of master students is foreseen.

In terms of cost we foresee 3000 euro for the exchange in 2 years (2 man-time visit for workshop/discussion in UPC: 1400 euro + 1 man-time visit for numerical model discussion/development in Uvigo: 1000 euro + invite CAE to FHR: 600 euro combining with the last conf. Of CREST).
