The analysis and description of geological processes in sedimentary environments have been widely defined by the frequency distribution of grain size (Friedman, 1961) whereas the change in the sediment textural characteristics has been used to evaluate the net sediment transport (Mc Laren and Bowles, 1985). The evaluation as a grain-size trend analysis (GSTA) is defined in Gao and Collins (1991, 1992) and LeRoux (1994a,b). The use of textural characteristics (grain size, sorting, and skewness) to infer the sediment transport was originally shown by a decrease in particle size in the direction of flow. In Sunamura and Horikawa (1971) a combination of grain- size and sorting identified four possible examples where it is possible to infer the direction of the sediment transport. In the early 1980s, the use of grain size, sorting, and skewness were pro‐ posed to infer sediment transport on the basis of the statistical analysis of sediment-transport paths along the transect (Friedman, 1961). Later bidimensional models of sediment transport pro‐ posed by Gao and Collins (1992), LeRoux (1994a) and Poizot et al. (2008) are supported by analytic geometry, vector analysis, and statistics to obtain more robust results of the magnitude and direction of the transport vectors. The GSTA is an excellent approach for establishing sediment transport in a variety of environments such as rivers, beaches, harbors, estuaries, continental shelf, and submarine canyons (Carriquiry and Sánchez, 1999; Carriquiry et al., 2001; Sanchez et al., 2008, 2009, 2010; Sanchez and Carriquiry, 2012). 1.1.
