| Parmi les régions Ouest Européennes, la région Poitou Charentes se caractérise dans sa dimension économique par la présence d'activités où les cultures marines, l'agriculture et le tourisme occupent une place prédominante. Cette identité, partagée par d' autres régions, notamment atlantiques, s'appuie sur l'exploitation de la ressource hydrique et implique de plus en plus des critères de haute qualité tant vis à vis des produits finis agricoles, conchylicoles, touristiques que vis à vis de l'environnement, des paysages et des eaux. Sur cet ensemble de points la Région est dotée d'atouts indiscutables. Cependant les contraintes liées à la disponibilité de la ressource hydrique continentale comme marine et à son maintien à un bon niveau de qualité, font... |

| A coastal river 380 km long, the Charente river has a catchment area of about 10,000 km2, flowing through the departments of Charente and Charente-Maritime, as well as a small part of the border departments: Dordogne, Deux-Sèvres, Haute-Vienne and Vienne. Its main affluents are the Tardoire, the Seugne and the Boutonne rivers. The highest part of the catchment area is located in Dordogne, at a height of 496 m, whereas the river itself originates from a spring located at a height of 250 m to the south-east of Rochechouart, in the Haute-Vienne. The average height of the catchment area is quite low. In its downstream part, from the Saint-Savinien dam to the ocean, the Charente is influenced by a dynamic tide. The actual estuarine part begins in... |

| Suedre River, a small river in Charente-Maritime, is 45 km long and drains a 380 km2 river basin. Its flow rate is about 20 m3.s(-1). Beyond the Saujon agglomeration, the river extends to the sea via a 25-km long estuary which, through the action of tides, becomes a sea arm reaching 1 km in width. Freshwater and salt marshes line the banks of the Seudre River. Freshwater marshes are occupied by large cattle farms and intensive, irrigated crops. Salt marshes are used for oyster finishingthe final, fattening process in oyster farming. The coexistence of both types of activity is sometimes problematic, particularly in terms of water management, a frequent source of conflict. The climate in Charente-Maritime is characterised by dry summers and rainy winters,... |

| Cette étude s'inscrit dans le cadre du projet européen SPICOSA (Science and Policy Integration for Coastal System Assessment), prévu pour la période 2006-2010. Cette initiative de recherche prise par l'Union européenne dans le domaine de la gestion des zones côtières vise la durabilité des littoraux européens. « A travers la prise en compte équilibrée des aspects écologiques, économiques et sociaux, le but général de SPICOSA est de développer de manière auto-évolutive une approche holistique des outils d'évaluation des options de politiques pour la gestion durable des systèmes côtiers ainsi que les conséquences des politiques en termes sociaux et économiques, quant du local au global ces écosystèmes sont soumis au changement des conditions... |

| Managing the water resource finds a special dimension on the coastal strip. This resource is not shared between the different users according to the classical schemes of catchment areas, linking quality and quantity. The measure of a river water flow turns into currents in the marine field and the freshwater volumes turn into salinity units illustrating the fresh water / salt water mix. As a consequence, in a participative management approach as recommended by the GIZC (Integrated Management of the Coastal Zone) procedures, it seems fundamental that the actors from the terrestrial and marine worlds and their interfaces share their perceptions in order to improve the quality of the management scenarios. This shared perception of the catchment area and... |
