Stationary and oscillatory flow through coarse granular materials have been investigated experimentally at Delft Hydraulics in their oscillating water tunnel with the objective of determining the coefficients of the extended Forchheimer equation. Cylinders, spheres and different types of rock have been tested for high Reynolds numbers. The extended Forchheimer equation coefficients will be derived during the ongoing analysis programme, and the dependency on differentparameters, such as the porosity, gradation and stone shape and possibly also the Keulegan-Carpenter number will be examined. Further, for the non-stationary term, the virtual mass coefficient will be derived
