Comments on 'Temporal assessment of sediment transport from beach nourishments by using foraminifera as natural tracers' [Coast. Eng. 52 (2005) 205-219]

摘要

Benavente et al. (2005) have carried out a very interesting study of foraminifera shell distribution in a nourished beach for estimating sediment pathways. After a 3-year morphodynamic study, by monthly sediment sampling, a complex pattern of transport was identified though, regrettably, this methodology only accounts for the behaviour of fine fractions. Nevertheless, as the chief engineer in charge of beach nourishments in the coast of Cadiz for the last 15 years, I consider that some items would have to be clarified; otherwise, they could lead to misinterpretations.
