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 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...
متن کاملAssessment of the Longshore Sediment Transport at Buarcos Beach (west Coast of Portugal) through Different Formulations
This study applies some of the most practical longshore sand transport formulations and evaluates their adequacy to estimate the total (suspended and bed load) longshore sediment transport rate (LSTR) at Buarcos Beach, in the West coast of Portugal. The straightforward methodology here present is simple to apply and therefore useful to quickly obtain a first estimate of the littoral transport i...
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 کاملThe Effect of Stormwater Controls on Sediment Transport in Urban Streams
Urbanization of a watershed increases impervious area, and consequently increases stormwater runoff. When left uncontrolled, these increases in stormwater runoff cause downstream flooding, accelerate channel erosion, and impair aquatic habitat. Increases in the magnitude and duration of stormwater runoff that accompany uncontrolled development allow a stream to carry more sediment than it could...
