On one day, Friday 4th April 2003, a series of detailed hydrodynamic, environmental and ecological measurements was conducted in the estuarine zone by more than 60 people. The purpose of the field works was to assess the complexity of a small estuarine system, the interactions between hydraulic engineering, biology and ecology, and to provide some assessment of the estuarine system that was heavily polluted four to five years ago. Field work was conducted from a low tide to the next low tide : i.e., between 6:00 am and 6:00 pm.
