Abstract: An exponential distribution of the bed-pressure fluctuations is used to estimate the depth within a porous gravel bed from which fine sediment of a given size can be removed. The coarsest grain size of the fine sediment ...

Abstract: The comparability of grain sizes emerging from different methods are discussed, including image-based grain-size analysis. Waterworked gravel-bed surfaces from laboratory and field experiments are analyzed in detail. Grain ...

Abstract: The statistics of pressure fluctuations above and within three types of porous granular beds such as in gravel bed streams, rivers, and man-made canals are investigated by data gained via laboratory flume experiments. The ...

Abstract: This paper presents an intrinsic approach to estimate air entrainment rates due to intake vortices based on large-scale laboratory measurements. Quasi-continuous measurements of the amount of entrained air were conducted ...
