Controls on strath terrace formation and evolution: The lower Guadiana River, Pulo do Lobo, Portugal

Geomorphology, 2018
The lower Guadiana River carves a wide canyon in the Variscan metamorphic rocks of the SW Iberian Peninsula and presents an exceptionally homogeneous and well-preserved case of a strath terrace (ST) some 40 km long and 400 m wide.

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 ...

A long-term hydrological modelling of the Upper Guadiana river basin (Spain)

Physics and Chemistry of the Earth, Parts A/B/C, 2003
Abstract The Upper Guadiana catchment has experienced a change from wetlands to dry lands induced by human action. The Soil and Water Assessment Tool model, a soil water budget simulator for agricultural watersheds, was applied to this catchment. The ability of the model to represent the impact of groundwater withdrawals on the hydrological behaviour

Real-time flow measurement in the river guadiana estuary using acoustic doppler technology

Proceedings of the IEEE/OES Eighth Working Conference on Current Measurement Technology, 2005., 2005
In the year 2004 a system was designed, installed and tested in the River Guadiana coastal plain estuary to provide with real-time net flow data to the Automatic Hydrological Information System, which is the control and monitoring tool of the River Guadiana Water Authority.
