Extraction of the indicator d 99.5 from the model results; d 99.5 is the distance from departure (meters) where more than 99.5 % of the rocks where stopped. Due to the measuring lines, this is in discrete 10-m steps. The gray curves are based on the same simulations as the curves in Fig. 2, but only the results for the big rocks are shown here. The upper line is without forest. Dashed lines are examples for d 99.5. Note that the y-axis is drawn using a logarithmic scale
