Modelling of Nearshore Sediment Transport
Abstract
The primary effort during the past year focussed on analysis of data obtained during a field experiment conducted at Cape Canaveral during Summer, 1987. Analysis was pursued using a new approach based upon examining the spatial and temporal characteristics of individual sand suspension events, as well as their statistical characteristics. The most interesting conclusions fell along two lines of investigation: (1) the presence of wave groups enhances the suspension of sand above that which would occur with randomly distributed waves with the same height distribution; and (2) the primary difference between suspension events which cause erosion and those which cause accretion relates to the phase of the wave in which the sediment is suspended off the seabed. This report included individual articles on the following topics: The structure of events of intermittent suspension of sand due to shoaling waves. A laboratory evaluation of optical suspended solids sensors exposed to sand mud mixtures; Acoustic measurements of suspended sand on the shoreface and the control of concentration by bed roughness; and Suspension of sand due to wave groups.
