The objective of this study, carried out in the Gironde estuary inlet, was to determine the nature of the seaward dispersion of estuarine water and suspended sediments during a spring tide and high river flow. On June 3, 19(7, three flights were made over the inlet, at mid ebb, low tide and mid flood. The planned flight at high tide was cancelled due to adverse meteorological conditions. During each flight, thermal infrared coverage was obtained, together with black and white photographs. These data were correlated with concomitant ground mesures of current velocity, salinity, temperature and suspended sediment concentration Four types of water masses were identified during the tidal cycle: estuarine "very warm and turbid" water; estuarine "cooler and... |

Les laboratoires côtiers de la DEL émettent chaque année près de 400 avis, à la demande de l'Administration. Après avoir situé les avis dans le cadre plus général de l'expertise, rappelé les obligations réglementaires de l'établissement et examiné les procédures internes, ce rapport analyse la demande, les sites concernés, la portée des avis en terme d'aménagement du littoral, les activités économiques impliquées, le temps passé et le coût pour l'Ifremer, etc. |
