Dinámica de formas de fondo en la desembocadura del estuario del Río Piedras (Huelva)

Abstract

The estuary of the Piedras River is a small and narrow estuary, with a reduced fluvial input and a wide spit in its mouth in whose apex expands a wide system of ebb-tidal deltas. The present work characterizes the dimensions, orientation and sediment grain size in the bedforms distributed on the different subenvironments of these tidal deltas. The study was done by means of direct measurements carried out during tides of different range. On the other hand, measurements of the tidal currents in the interface water-bottom have been carried out to associate the studied forms with the currents that generated them
