HYDRODYNAMIC STUDY OF A DRAINED BEACH

The present paper deals with an experimental investigation performed at Large Wave Channel (Grosser Wellen Kanal, GWK) in Hannover. The general aim of the project was to improve the knowledge of the hydrodynamic and morphodynamic behavior of a beach equipped with a Beach Drainage System (BDS). Tests allowed to investigate the shore zone processes, in drained and undrained conditions, including in-filtration and ex-filtration flows. In this paper the experimental set up is briefly described and only the hydrodynamic results are presented
