Groundwater Flow On A Drained Beach

Abstract
This paper deals with the analysis of the groundwater flow on a drained beach.
Infiltration processes in static conditions (without running waves) are numerically
simulated by using HYDRUS-2D software. Nevertheless, field and laboratory
experiments show the possibility of studying the influence of the system on both
nearshore hydrodynamics and morphodynamics using a numerical model able to
reproduce the drainage main physical processes. It is fundamental in order to
define the main Beach Drainage System (BDS) design criteria which, to date, are
not yet defined. The groundwater flow through a partially saturated porous media is
described using Richard’s equation. Numerical results are then compared with the
experimental ones obtained during an intensive experimental program performed
on a BDS prototype at the GrosserWellen Kanal (GWK) in Hannover. In particular,
the study focuses on the BDS influence on the groundwater table inside the beach
and drained flows.
