Abstract: The effective erosion and transport of deposits on horizontal and slightly inclined rigidboundaries were investigated in a combined field and laboratory study.Non-cohesive gravel as well ascohesive materials were washed away by flushing surges.Two different devices -a tipping bucket and arectangular tank -were used in order to produce surges on the concrete floor of a long rectangularsedimentation basin of a waste treatment plant(see figures 1 and 2).The deposits were placedartificially,therefore their properties were clearly defined.Although the presented comparison betweengravel and sand-sludge deposit behaviour was perfomed in a basin,the results may also be of interestfor the maintainance of tail water channels of power stations,ship locks,and survey stations,andsewers.
