Adaptation of coastal flood protection systems - Conceptual contributions and research of methodological developments in the context of climate change and land planning

Coastlines are subject to multiple developments related to land use planning and the effects of climate change, developments likely to generate a strong increase in the risk of coastal flooding. This PhD on published works focuses on systems to protect against this hazard, and presents: • a bibliographical analysis on the concepts, methods and strategies for adapting protection systems through strengthening their resilience. This analysis is based on the essential assumption that a coastal flood protection system is a social-ecological system; • in relation to the state of the art and with the aim of completing it, a summary presentation of the research that led to: ◦ the revision of the concept of a coastal flood protection system; ◦ the establishment of a methodological framework to strengthen the resilience of protection systems.
