This coastal system is a small and narrow estuary, with a reduced fluvial input that develops a wide littoral spit in its mouth in whose apex a wide ebb-tidal delta is developed. On the back area of the deltas flood and ebb tidal currents develop a variety of sandy bedforms. The comparison of flood and ebb forms allows analyze the hydrodynamic regime and the sand mobility due to the action of the main currentsspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/EstuaryBedformsSedimentary dynamicsjournal articleopen access
