“…Other arguments supporting the stability of beach sand compostions are that, apart from the deltaic regions of the major rivers such as the Ebro, the Rhône and the Po, the fluvial networks have not significantly changed over the past 2000 years (see also Rizzini, 1974;Gandolfi et al, 1982;Viñals and Fumanales, 1995;Guillén and Palanques, 1997;Santisteban and Schulte, 2007;Larue, 2008;Rey et al, 2009). More information on the structural buildup and stratigraphy of the Ebro (Maldonado, 1972(Maldonado, , 1975Aloisi and Duboul-Razavet, 1974), Rhône (Oomkens, 1970;Aloisi and Duboul-Razavet, 1974;Vella et al, 2005) and Po (Nelson, 1970;Amorosi and Milli, 2001) delta systems can be found elsewhere.…”
