ABSTRACT

The sustainable use of the water is a priority at the planetary level, being, therefore, critical to plan and to manage the water resources on a sustainable basis. The Water Framework Directive aims at regulating and establishing guidelines. With the data spatially collected, two scenarios have been simulated, verifying the hydric availability/need associated to each scenario. Therefore, an increase of the population to be supplied by this basin is to be expected, as well as the glimpse of the water resources in the year 2070, in view of the expected climatic changes. With the data obtained, it is verified that, with the growth of the population to be served, the water availability will not fulfill the needs, and with the rainfall decrease over the years more serious results in the hydric availability are signaled, and catastrophic deficits in the hydric balance of this hydrographical basin.

RÉSUMÉ

L'utilisation durable de l'eau est une priorité à l'échelle mondiale, obligeant à définir une gestion durable des ressources hydriques. L'Union européenne a établi un cadre communautaire, Directive-cadre sur l'eau, pour la protection et la gestion des eaux. A partir de données recueillies du bassin hydrographique Sôrdo (Portugal) ont été effectuées deux simulations: i) la disponibilité et le besoin du bassin, prenant en compte l'augmentation de population à desservir; ii) la disponibilité et le besoin du bassin en 2070, tenant compte des changements climatiques. Les résultats obtenus prévoient une insuffisance d'eau pour satisfaire l'accroissement de population et présentent un bilan hydrique catastrophique dû à la diminution de la pluviométrie, pour le bassin hydrographique Sôrdo qui dessert aujourd'hui la capitale régionale du nord-est du Portugal.
