Sediment transport under coastal waves

(D. Hurther, J. Chauchat)

This research activity is devoted to the improvement of sand transport modelling across the coastal nearshore region affected by the turbulent wave breaking process and its dynamical interaction with bed morphology. Several intensive measurement campaigns have been conducted for this purpose in 2014, 2016 and 2018 under full-scale surface wave conditions in the large-scale wave flumes of U. Polytechnic of Catalunya (Spain, 100m long) and of U. Hannover (Germany, 300m long). The study addresses hydrodynamic flow processes including the turbulent Wave Boundary Layer properties (van der Zanden et al. 2016, 2018, van der A et al. 2017) and their effect on suspended load and bedload sand transport as a sheet flows (van der Zanden et al. 2017a, 2017b, Fromant et al. 2019) across the shoaling, outer and inner surf zones.
