摘要

The Authors are to be commended for having made a significant effort to clarify some aspects of physical modelling of dike breaching due to overtopping. This phenomenon was experimentally also investigated at the University of Belgrade, using different model properties. Effects of cohesion and seepage were included in an attempt to simulate the physics as much as possible (Jovanovic 1988). An overtopped earth structure was exposed to effects of gravity, shear stresses due to overflowing water, hydrostatic pressures, forces of cohesion, and pore pressures which developed as saturation takes place. Since all these factors affect the structural stability, they need to be accounted for when specifying the similitude conditions for scale model investigations.
