“…In order to analyse the sediment transport directions, the method proposed by McLaren and Bowles (1985) and modified by Gao and Collins (1991) was followed. The model is based upon comparison between one sample and adjacent samples to reach a conclusion on "transport vectors", considering some patterns characterising movements based on the granulometric parameters For the hydrodynamic modelling, the TRIMOD-ENA 3D finite element numerical model was applied.…”

SUMMARY: During 2000 and 2001 and at the beginning of 2002, current meters were deployed at 25, 50 and 110 m water depths along two transects: one offshore of San Sebastian and the other offshore of Hondarribia. At the same time, hydrographical cruises and the collection of sediment samples were undertaken over the coastal section. The aim of the study was to improve the knowledge of seasonal changes in the coastal water circulation. The main results obtained are three-dimensional measurements of water flow, a description of the seabed sedimentology between 50 and 90 m depth, and an improved description of the effect of the circulation patterns on the dispersion of pollutants. Two different patterns of surface water circulation were identified, related to oceanographic and meteorological conditions in autumn-winter and spring-summer. Analyses undertaken on three-dimensional current meter data also improved the understanding of seasonal variations in marine currents. All the field data were incorporated into a numerical model for the simulation of currents. This numerical model contributed, together with the field measurements, to the improvement of the description of general seasonal variability patterns in the currents. The effect of this circulation on the dispersion of pollutants was also analysed.

“…Mclaren et al [41] and Mclaren and Bowles [42] concluded that successive deposits along the transport path must either become more sorted, finer and more negatively skewed, or become more sorted, coarser and more positively skewed. Gao and Collins [43] modified this hypothesis and developed net sediment transport patterns-Grain Size Trend Analysis (GSTA), which has been applied in multiple marine environments [44][45][46][47][48][49].…”

“…beaches, rivers, continental shelves. Among these applications of sediment trend analysis, the two dimensional and most widely used in open marine environments for the definition of trend vectors approach is the Grain Size Trend Analysis (GSTA)method, introduced by Gao and Collins (1991;1992;1994) and assessed positively by Poizot (2006).The technique can be applied to inner continental shelves and coastal environments and has been appliedin several cases with varying success (e.g. Rhone River coast by Masselink (1992), La Salie beach at Southwest French coast by , the Belgian continental shelf by Pedreros et al (1996) and Van Wesenbeeck & Lanckneus (2000).…”

Grain size trend analysis is a method that determines sediment transport direction, based on the relationship of grain size parameters (mean size, sorting, skewness). The application of the method in the seabed sediments of Alexandroupolis Gulf showed that there are three different sub areas of distinctive sediment movement of bottom sediments (water depths <40 m):(i) the eastern part, which is mainly influenced by the Evros river water/sediment influxes; (ii) the central part that is primarily controlled by the wave activity; and, (iii) the western part that is mainly influenced by the wind driven and/or thermo-saline coastal circulation.
