IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

PHYSICAL AND NUMERICAL MODELLING OF DIFFERENT NOURISHMENT DESIGNS
Author : ALESSIO GIARDINO , YORICK BROEKEMA , JEBBE VAN DER WERF , ARNOLD VAN ROOIJEN , & MICHALIS VOUSDOUKAS
In this paper, the morphological development of different nourishment designs is investigated by means of physical experiments and numerical modeling. In particular, experiments and model runs have been carried out for one design of beach nourishment and two different designs of shoreface nourishments, including different wave conditions. Models and data have shown the effect of the nourishments on wave height reduction across the profile, which leads to a reduction of the eroded volume at the beach. Locally, at the location of the nourishments, a clear increase in flow velocity and concentrations is shown by both, model and data results. Finally, the effect of multiple fraction and a multi- layered bed stratigraphy were also included in the simulations, allowing the simulation of nourishment with different grain characteristics compared to the native beach.
