Abstract

This paper reports a method of monitoring small movements of clasts just prior to entrainment and the ingress of fine matrix material into framework gravels using digital image analysis. The method presented involves the analysis of digital video imagery taken through the glass side-wall of a laboratory flume using a digital CCD (charge-coupled device) camera. Experimental results showing dilatation of a gravel framework and rapid infiltration of fines just prior to entrainment are discussed
