Some important parameters for the hydraulic characterization of a site / soil material can only be derived from laboratory experiments. Laboratory measurements allow the determination of various parameters under defined boundary conditions, which allows a high repetition rate of the experiments and thus also a well-founded statistical evaluation of the determined parameters.
