Abstract
Recognizing the need for improved measurement and parameterization of sediment resuspension, this paper presents a review of the major methods now in use for alleviating this need. Special attention is devoted to reviewing methods for obtaining sediment concentration profiles by acoustic scattering methods and the microcomputer based C-DART Tower developed by the authors to simultaneously measure wave, current, and sediment profile data. The presence of spatial data requires a new approach to its analysis. A generalized pattern recognition program for geophysical flows is discussed.
