Momentarily the determination of the static stability of rock on mild slopes can be split in roughly two paths, the empirical and the physical approach. However, both the approaches have their limitations from which one could conclude that neither approach is currently an accurate description of the stability of rock on mild slopes under wave attack. The empirical approach by van der Meer [1988] has to be extrapolated outside its validity region and is deemed to be too conservative by Schiereck and Fontijn [1996]. The physical approaches on which the software XBeach-G[1], runs are capable of globally determining dynamic profile response reasonably well however they cannot accurately determine static stability. From this lack of an accurate approach to determine the stability of rock on mild slopes under wave attack, follows the research question of this thesis: “How should the stability or rock on mild slopes be described?” To determine how to describe the stability of rock on mild slope under wave attack, a test plan was set up. The test plan was split into two parts, firstly the empirical approach and secondly the physical approach. The empirical approach is based around the formula of Van der Meer [1988] for plunging waves. Whereas the physical approach follows the methodology of Xbeach-G. For which the input parameters have been derived by the means of a combination Bubble Image Velocimetry (BIV) and Particle Image Velocimetry (PIV).
