| Zusammenfassung |
| The Gironde Estuary, one of the largest European ones, presents temporary
low dissolved oxygen content in its fluvial section close to the Bordeaux
urban area. In a context of population growth and of long-term environmental
changes, the development of a high-frequency monitoring programme of the
fluvial-estuarine system of the Gironde, called MAGEST (MArel Gironde
ESTuary), had appeared essential to address current and future water-quality
issues/evaluations. The objectives of the MAGEST survey program are to
establish a reference database to improve the knowledge of the Gironde
Estuary functioning, encompassing the aspects of hydrology, sediment
dynamics and biogeochemistry. Through examples of results from intratidal to
seasonal time scales, we demonstrate how such a long-term, high-frequency
monitoring of a fluvio-estuarine system is of valuable interest to extract
the main trends of its functioning and of the water quality in relation to
external forcings (climatology, urban wastes, land use, ...) and to
predict the future evolution of an estuary with global and environmental
changes. |
