Fig. 15

Comparison of convergence results from measurements and simulation. Measured and simulated displacements of the presented distances are shown over time. The blue symbol (measurements) and line (simulation) present the displacements of the diagonal distance between points 3 and 4; the green symbols and line reflect displacements of the vertical line between points 2 and 4, the grey symbols and line indicate horizontal displacements between points 1 and 3. Measurements were carried out for 10 years. Keeping the differences between measurement and simulation results in mind, the numerical simulation allows for a prediction of the convergence of the niche over a longer time period
