RT Conference Proceedings T1 Physical characterization of the Guadiana Estuary using a 3D model A1 Calero Quesada, María Concepción A1 Delgado, Javier A1 Garel, Erwan A1 García-Lafuente, Jesús A1 Martins, Flavio A1 Moreno-Navas, Juan K1 Ecología de estuarios AB Guadiana estuary is an intertidal estuary situated in SW of Iberian Península, the latest 50 Km of which constitutes the natural border between Spain and Portugal. Tidal influence extends to about 80 Km upstream. The Guadiana River presents a high seasonal irregularity with wet winters and dry summers.A 3D hydrodynamic model based on the MOHID System has been developed to study the hydrodynamics of the Guadiana Estuary. The model has been validated by comparison the output with in situ data measurements in several points along the estuary.
