dc.description.abstract | Measurements of the velocities when a steady current is flowing over a rippled bottom are presented. The bottom consisted of triangular bars at regular crest to crest spacing of 10 cm. One set of experiment was conducted in a glass flume and another set was conducted in a wave basin covering a larger width of flow. The results for the basin experiments show that the velocity vector turns from near-parallel to the ripples to the main flow direction as the distance above the bottom increases. The roughness determined from the normal velocity is in agreement with results obtained in a glass flume for flow normal to the same bottom roughness configuration as well as with the findings of Mathisen & Madsen (1996) and Barrantes & Madsen (2000). Thus, the conclusion of the present study is that bottom roughness is directional dependent for currents over 2D bottom roughness features. | |
