Hoofdstroming contra menglaag: De invloed van een menglaag op het begin van bewegen van bodemmateriaal

Experimental research on the stability of bed material behind a backward facing step. Measured is the stability as a function of the local velocity and the local turbulence (turbulence intensity) due to the eddy formation.

Transport van stenen van een granulaire bodemverdediging

Experimental research on the stability of bed protection and transport of stones on such a bottom protection. Investigated were the effects of duration and magnitude of the load, the shape, and placing density of the stones.
