Abstract
Permeability measurements were carried out in a U-tube tunnel to study flow through coarse granular material. The results are of importance for studying the flow in permeable structures such as rubble-mound structures and gravel beaches. The contributions of laminar and turbulence friction terms have been determined as well as the importance of inertial resistance. Differences between stationary flow and oscillatory flow conditions have been studied. The influence of oscillatory flow conditions on the porous flow friction coefficients have been implemented in new expressions for porous flow friction coefficients. These can be used both to study scale effects in small-scale physical models and for the implementation in numerical models simulating porous flow.
