Objective:

Mobile Bay is a relatively wide and very shallow estuary. The natural forcing of high-speed winds associated with storms and hurricanes can generate surface waves that are responsible for the loss of wetlands and habitats in Mobile Bay. The wind waves generated by the frequent, moderate wind speed may be significant to the sedimentary dynamics of Mobile Bay. Conversely, the large volume of ship traffic through the deep ship channel and in the Port of Mobile also can generate surface waves that could have similar impacts as the wind waves. In comparison with the understanding of wind waves, however, little is known about the characteristics of the ship waves in Mobile Bay. Furthermore, the effects of the surface waves caused by either winds or ships on the sediment suspension or the turbidity in this shallow estuary are virtually unknown.

The long-term objectives of the research project are to quantify the natural and human-induced impacts on the physical processes in Mobile Bay, and to understand the consequences of those impacts on the ecosystems and habitats. The specific objectives of the project are to develop a platform for the investigation of wave processes in the Mobile Bay estuary, and to characterize the surface waves generated by the natural forcing of episodic winds (storms and hurricanes) and sustained winds (with the most frequent occurrence of wind speed and direction), as well as by the human activity of cargo transport. This will allow us to compare the impacts of both types of surface wave on sediment suspension and alongshore sediment transport in Mobile Bay.
