The European Union established a framework for Community action in the field of water policy. Considering the need for the natural resources protection and conservation, the Water Framework Directive 2000/60/EC Directive was adopted, involving the efforts of all Member States in the task of achieving good status for all waters, in which the aim of achieving good ecological state for natural ecosystems can be included. Within this context, the main objectives of this study are: the characterisation and quantification of the degradation degree in the fluvial ecosystem of the Alcoa river drainage basin, and to that end it was used the Predictive Ecological State methodology; and planning restoration actions for the most degraded stretches of the river system which deteriorate under the effect of human actions. Based on the results obtained, a Map of River Corridor Conservation Status was developed for the Alcoa river catchment area with the intend of revealing the degree of degradation of the river streams, and a Map of River Restoration Planning was developed which summarizes the restoration actions to be implement in the drainage basin.
