Construction of a simplified hydrographic network based on the Carthage® database.

Abstract

To help public organisations in charge of aquatic management to achieve objectives of good ecological status of water bodies required by the European Water Framework Directive (WFD), it is essential to model flow in the hydrographical network. Indeed, the classification of water bodies requires the analysis of upstream-downstream relations. In its present state flow cannot be modelled in the DB Carthage® leading us to simplify the initial database.
