Bedform alignment in directionally varying flows
D. M. Rubin, R. E. Hunter
1987, Science (237) 276-278
Many kinds of sediment bedforms are presumed to trend either normal or parallel to the direction of sediment transport. For this reason, the trend of bedforms observed by remote sensing or by field observations is commonly used as an indicator of the direction of sediment transport. Such presumptions regarding bedform...
