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...

[1] We present a numerical investigation of longshore currents driven by breaking waves on barred beaches. Alongshore inhomogeneity in the wave envelope or bathymetry leads to the generation of strong dipolar structures when the waves are breaking. The dynamics of these structures transfer momentum from the bar of the beach into the trough. This study is pursued using a new model that allows lo...

Longshore transport experiments were conducted in a large-scale physical model to evaluate predictions of the CERC formula with measured longshore sediment transport rates. It was found that the CERC formula produced reasonable estimates if the coefficient K was calibrated and applied to waves with similar breaker type. The calibrated K values are much smaller than values that are commonly used...

In the present paper various transects perpendicular to Iranian Makran coasts (Chabahar-Gawater) were studied using satellite image processing, field observations, sandy shore profiling and grain size analysis to evaluate sedimentology and geomorphology of the area. Data revealed that the study area includes exposed rocky shores (52%), sandy shores (40%), and mud flats (8%) sheltered in estuari...
