RT Journal Article T1 Movilidad de las formas de fondo en la desembocadura del estuario del Río Piedras (Huelva) durante las mareas vivas T1 Bedforms mobility in the mouth of the Piedras river estuary (Huelva) during the spring tides A1 Delgado Rodríguez, Irene A1 Morales González, Juan Antonio A1 Gutiérrez Mas, José Manuel AB The present work analyzes the bed mobility in the outer area of the estuary of Piedras River by observingthe changes of morphology, dimensions and orientation of bedforms by means of the use of technical ofSide-Scan Sonar. This coastal system is a small and narrow estuary, with a reduced fluvial input thatdevelops a wide littoral spit in its mouth in whose apex a wide ebb-tidal delta is developed. On the backarea of the deltas flood and ebb tidal currents develop a variety of sandy bedforms. The comparison offlood and ebb forms allows analyze the hydrodynamic regime and the sand mobility due to the action ofthe main currents YR 2007 FD 2007 LK http://hdl.handle.net/10272/8371 UL http://hdl.handle.net/10272/8371 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 13 jul 2026
