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 drained beach to define reliable design criteria of the system.

Abstract

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 drained beach to define reliable design criteria of the system. The tests allowed to investigate the shore zone processes, including in-filtration and ex-filtration flows. The obtained results gave information to discuss the weakness and strength points of the Beach Drainage System (BDS) as a tool able to reduce beach erosion. This paper shows the experimental set up and first results concerning water table behavior. Drain efficiency in water table lowering has been evaluated. Measures of water table levels, also in undrained conditions, can be useful to investigate shore zone hydrodynamics.
