Abstract
    The hydrodynamics of a ship that are associated with lock entry are described empirically and mathematically. Emphasis is put on the generated translation waves. The six-waves-model of A. Vrijburcht is used to calculate the wave system in the lock. These calculations are compared with empirical data and the six-waves-model is improved in a theoretical and empirical manner. The most significant adjustments to the model are the introduction of speed-dependency, taking account of the ship’s hull shape and of the layout of the lock entrance. The model is compared to experimental results with scale models of a bulk carrier and a container carrier.
