For the design of granular bed protections often a stability parameter is used. The stability parameter represents the forces that are acting on the stones and is used to predict the response of the bed to these forces. Existing parameters are often derived for a limited range of application. When the parameter is used outside this range, the...

The current research is aimed at finding a proper relation between flow forces acting on the bed and the bed response. To this end, experiments were carried out in which both the bed response (quantified by a dimensionless entrainment rate) and the flow field (velocity and turbulence intensity distributions) are measured. The three available...

The current research is aimed at finding a dimensionless stability parameter for non-uniform flow in which the effect of turbulence is incorporated. To this end, experiments were carried out in which both the bed response (quantified by a dimensionless entrainment rate) and the flow field (velocity and turbulence intensity distributions) are...

Het onderwerp van deze studie is een niet-uniforme stroming waarin sprake is van een plaatselijk verhoogde aanval op het bodemmateriaal door de lokaal hogere turbulentie. In een 15 m lange stroomgoot met een breedte van 40 cm is door middel van een backward-facing step ofwel afstap een niet-uniforme stroming gecreeerd. Om de schade aan de...
