Wave-Sediment Interaction in Muddy Environments: A Field Experiment
Abstract
OBJECTIVES The objectives of Years 1 and 2 (2007-2008) of the Coastal Geosciences (CGS) project was to conduct a pilot field experiment (2007), then a full field experiment (2008), in collaboration with other researchers funded by ONR CG program. The pilot experiment has tested the instrumentation and data analysis procedures. During the major field experiment effort in 2008 (Year 2), a total of 5 tripods were deployed at locations fronting the Atchafalaya shelf and further westward along the Chenier Coast near Freshwater Bayou. The tripods carried instrumentation for coherent measurements of waves and near-bottom sedimentary processes, including vertical structure of velocities and suspended sediment concentration, and lutocline position and motion. The dataset was supplemented with monitoring of bed character (deposition rate, porosity and stratigraphy). The project represents an effort to obtain detailed field observations (previously lacking) about the processes associated with fluid-mud layer formation and bed response to wave events, necessary for effective modeling of wave propagation over muddy shelves, as well as the role of wave activity on the processes related to the development of subaqueous clinoforms. The goal of the DURIP project was to build up the field instrumentation base to support the CGS-funded field experiment effort.
