%X Experiment to measure stone stability under accelarating flow. During the experiment 78 test series have been performed with changing wave steepnesses in order to create scenarios of similar horizontal near-bed velocities, but with different accelerations. Another 22 of such tests series have been carried out with stones that have a smaller diameter.
It has been assumed that if there is a relation between the threshold of motion and accelerations then for some combinations of a velocity and acceleration there are stones that move while in other cases with the same near-bed velocities, but a lower acceleration, there will be no movement of the same stones.
