| Abstract: | Flume experiments were performed on four sediment mixtures sampled from the offshore Galveston dredged material disposal site in order to determine t their critical erosion velocity, shear stress, and modes of sediment transport. Also, an analysis of the offshore Galveston hydrographic regime was performed using meteorological and oceanographic data. The results of the flume experiments indicated that the four sediment mixtures eroded similarly. Extrapolation of flume results to recorded off-shore bottom current speed measurements indicate that bedload erosion occurs much more frequently near the northern margin of the disposal site. Also, net bedload transport of disposal material is oriented down the coast or offshore from the disposal site, suggesting that material will not likely return to the channel proper as shoaling sediment. |
