RATE OP SEDIMENT MOTION USING FLUORESCENT TRACER

Abdel-Latif Akadib

Abstract


A rational design of coast protection works requires a knowledge of the behaviour of beach under natural conditions. The estimation of the littoral drift rate is thus a necessary preliminary to the analysis of the cause of beach erosion and the evaluation of the effect of projected remedial measures. This study presents a method for estimating the rate of littoral drift along sandy beaches. The derived method is based on the use of fluorescent tracer, and observing the tracer concentration reaching the different profiles along the study zone, as function of location and time of sampling. Steps followed in estimating the rate of littoral drift, using the derived formula, are included in this paper.
