Abstract:

Many physical, chemical, and environmental factors govern the rate of cohesive particle sedimentation in aquatic environments. A new information-based model that uses experimental information to derive governing parameters, while predicting removal through power law relationships, is proposed and tested. Analytical solutions derived for this model are shown to be applicable over large ranges of concentrations and to various fluid-sediment environments.
