The study of coastal habitats and interactions between biotopes and biocenoses
DHYSED is pursuing its research into the integrated functioning of coastal ecosystems and their vulnerability, through the study of coastal habitats, interactions between biotopes and biocenoses and their modeling.
Several model species (microphytobenthos, crepidulas) and specific habitats (estuaries, bays and lagoons, plateaus) were studied, with a particular focus on eelgrass beds. Their influence on hydrodynamics, sediment trapping and erosion was observed experimentally and in situ, then conceptualized and ultimately modeled on the scale of a remarkable pilot site, the Arcachon Basin. The laboratory is currently developing an innovative hybrid modeling methodology, combining deterministic modeling with machine learning and Bayesian networks.
