Modeling Fluid Mud

Author(s): Hall, C.

Fluid mud is defined as a high concentration aqueous suspension of fine-grained sediment in which settling is substantially hindered. Fluid mud occurs in many ports and channels around the world. It can severely affect navigation due to the sharp increase in sediment concentration returning a false bottom to sonar systems, and the fluid mud can fill in channels faster than it can be dredged, restricting port access. Fluid mud can also suffocate benthic organisms or contribute to eutrophication. This study is designed to further advance the field of fluid mud modeling to aid in the prediction of fluid mud formation and movement. Most available hydrodynamic models do not include a fluid mud routine. The addition of fluid mud equations to these existing models could greatly enhance sediment process modeling in areas that experience fluid mud. These equations calculate formation, dissipation, flow, and consolidation to adequately describe the physical processes affecting fluid mud. Modeling results using these equations compared with field data as well as laboratory experiments will determine their usefulness. Laboratory experiments include measuring the flow of fluid mud under shear stress and on a slope. With accurate prediction of the physical processes governing fluid mud, dredging alternatives could be developed to reduce dredging requirements and improve port access.

Responsible Site Design: Implementing Innovative Stormwater Management Strategies

The primary goal of the workshop is to create a dynamic learning experience that examines the role of stormwater management in the built environment. The workshop will focus on integrating ecologically sound water management approaches into site design. After the workshop, attendees will be familiar with the following concepts and technical issues:

  • Knowledge of the stormwater treatment chain
  • Knowledge of the impact of land use codes on stormwater management
  • Application of a design process that mitigates the effects of stormwater on-site
  • Knowledge of the relationship between land use codes and design for innovative stormwater management
