This paper presents an overview of aone-degree-of-freedom dynamic behavior typical for rock blocks in turbulent flows.Turbulent flows such as jets impacting a plunge pool or plunging river flows around bridge piers may generate severe dynamic pressures that may be transmitted through the joints separatingthe blocksfrom their foundations.
