Originální abstrakt

Scour resistance of dike material is an essential phenomenon when assessing dike breaching due to overtopping. Usually the resistance of particular materials against scouring is determined via experimental modelling. In the literature sources many recommendations and also empirical formulae are introduced. Some of them are based also on experience from overtopping of real structures during floods. In this paper, summary of past experimental results is carried out. Individual approaches and formulae are compared and assessed from the viewpoint of their applicability on steep slopes. The resulting recommendations can be used as a basis when assessing threshold non-scouring velocities or critical shear stress as a part of simulation of dike breaching.
