Longshore Sediment Transport Rate Measured by Short-term Impoundment
The total longshore sediment transport rate in the surf zone was measured at a temporary groin installed at Indian Rocks Beach, west central Florida. Approximate mass balance between updrift accumulation and downdrift erosion, which served as an indicator of reliability, was obtained in four of the six runs, which were subjected to further analysis. Magnitudes of three of the four transport rat...
متن کاملDevelopment of a Computer Model for the Prediction of Littoral Sediment Transport Rate
In this paper, longshore sediment transport in littoral zones is investigated. For investigation of sediment transport in the nearshore zone, the effects of waves, currents and topographical conditions of coast are considered. Linear wave theory was used for the investigation of the wave behaviour. Governing equations of littoral current are continuity and momentum ones. For calculating concent...

متن کاملMeasuring Longshore Sediment Transport in a Large-Scale 3-Dimensional Laboratory Facility
Aiming at improving present understanding on longshore sediment transport (LST), the U.S. Army Engineer Research and Development Center recently established a Large-scale Sediment Transport Facility (LSTF). The 3dimensional movable-bed facility has the capability of simulating wave conditions that are directly comparable to annual averages along many low energy coasts. Wave, current, and sedime...
متن کاملInfluence of Grain Size on Sediment Transport Rates with Emphasis on the Total Longshore Rate
This Coastal and Hydraulic Engineering Technical Note (CHETN) summarizes the state of understanding of the influence of grain size on surf zone sediment transport and is a companion to Smith et al. (2004). This CHETN discusses details of bed-load and suspended load transport, and the classical bed-load regime is shown to encompass two distinct modes of transport. Four LST models with varying le...
