Abstract

The aims of this study are to identify variables as well as thresholds controlling different obstacle mark morphometries and to incorporate these into a simple statistical model. To achieve this, available field and laboratory studies on that topic are reviewed first. Secondly, the results of laboratory flume experiments are analysed and compared with other available laboratory and field data. The results of this work have shown a significant relationship between the morphometry of fluvial obstacle marks and obstacle Reynolds number, especially when morphometric variables were combined. Further validation, calibration and extension of this approach will help to adequately asses the influence of obstacles in the fluvial environment on micro- and meso-scale processes of sediment transport
