Study of the dynamics of estuarine and coastal waters using remote sensing: the Tinto-Odiel estuary, SW Spain

Wetland Loss by Erosion in Odiel Marshes (SW Spain)

“…Many infrastructures have been constructed closed to Odiel marshes that may reduce sediment supply to the estuary favouring marsh erosion, such as breakwaters, harbours and water reservoirs. OJEDA et al (1995) identified anthropogenic alterations of the hydrodynamic conditions of the Odiel marshes, which may affect erosion / accretion processes through the modification of currents and sediment supply (CHMURA et al, 2001). The lower rates of erosion in the upper estuary might also reflect lower wave energy, a suggestion that is also consistent with the observation of higher erosion rates adjacent to the large navigation channels.…”

“…Sediment accretion rates (approximately 5 mm year-1) indicate fast infilling of the estuary during the two last millennia (LARIO, 1996). Infrastructures such as dykes, breakwaters, harbours and water reservoirs have modified the hydrodynamic and the sediment supply in the estuary of Odiel and Tinto rivers (OJEDA et al 1995). On the other hand, the main channel of the estuary is dredged continuously to allow vessel traffic.…”

Composition and Transport Dynamics of Suspended Particulate Matter in the Bay of Cadiz and the Adjacent Continental Shelf (SW - Spain)

“…Satellite images of the Bay of Cadiz have been recorded by the satellite TM Landsat, using bands 2 and 5, and a spatial resolution of 30x30 m. Landsat images has been analysed to obtain extent and direction of turbidity plumes in several hydrodynamic situation in Cadiz bay and inner shelf waters. The process of the images has been carried out according to the methodology described by [58].…”

Sediment Quality and Possible Uses of Dredged Materials: The Ria De Aveiro Lagoon Mouth Area (Portugal)

“…Sediments are essential, integral and dynamic elements of these areas (e.g. Jouanneau and Latouche, 1981;Ojeda et al, 1995;Wang and Andutta, 2013).…”
