ABSTRACT Portela, L.I.; Custodio, A., and Trigo-Teixeira, A., 2016. Deposition in flowing water of fine sediments under different salinity conditions. In: Vila-Concejo, A.; Bruce, E.; Kennedy, D.M., and McCarroll, R.J. (eds.), Proceedings of the 14th International Coastal Symposium (Sydney, Australia). Journal of Coastal Research, Special Issue, No. 75, pp. 118-122. Coconut Creek (Florida), ISSN 0749-0208. While the effect of salinity on the settling of fine sediments has been shown to be important in laboratory experiments, only a few studies have attempted to investigate depositional properties in flumes under different salinity conditions. This paper examines the effect of salinity on the deposition in flowing water of fine sediments collected in the Tagus estuary. The sampling site is located in the middle-upper reach of the estuary, where fine-grained sediments are the dominant intertidal material and tidal currents the major transport mechanism. The experiments were conducted in an annular flume (me...
