Particulate metal distribution in Guadiana estuary punctuated by flood episodes

Estuarine, Coastal and Shelf Science, 2006
The distribution of major (Al, Ca, Mg, Fe and Mn) and trace metals (Zn, Cu, Pb and Cd) in particulate material was determined in different flow and tidal conditions along the Guadiana estuary. Under moderate river flows, concentrations of Al in SPM decreased seawards, while Ca and Mg showed an opposite trend reflecting the physical mixing of fluvial ...

Crustacean assemblages along the Guadiana River estuary (south-western Iberian Peninsula)

Journal of the Marine Biological Association of the United Kingdom, 2010
The spatial distribution of the subtidal crustacean assemblages of the Guadiana River estuary was studied previous to the building of the Alqueva Dam (the biggest dam in Europe). The differences between an estuarine and marine environment seem to be the main reason responsible for the composition and distribution of the ...

Status of the Guadiana Estuary (south Portugal) during 1996-1998: An ecohydrological approach

Aquatic Ecosystem Health & Management, 2001
Abstract The aims of this study were to monitor basic hydrological and ecological characteristics of the Guadiana Estuary (1996-1998) before the construction of the Alqueva dam. This work was carried out to determine how environmental factors affect seasonal and tidal variations of plankton populations in the estuary.

Converse effect of flooding on intertidal macrobenthic assemblages in the Guadiana estuary

Journal of the Marine Biological Association of the United Kingdom, 2013
The effects of winter flooding on the intertidal macrobenthic assemblages in the Guadiana estuary were studied by analysing several ecological parameters (abundance, biomass, species richness, diversity, degree of dominance of annelids and deposit-feeders species and number of predator species) as well as changes in the composition of the assemblages ...

Tidal and river discharge forcing upon water and sediment circulation at a rock-bound estuary (Guadiana estuary, Portugal)

Estuarine, Coastal and Shelf Science, 2009
The relative impacts of tidal (neap, spring) and river discharge (including a flood event) forcing upon water and sediment circulation have been examined at the rock-bound Guadiana estuary. Near-bed and vertical profiles of current, salinity, turbidity, plus surface suspended sediment concentrations (SSC, at some stations only), were collected at the ...
