This working paper is part of a watershed restoration project and is based on a pre-classification of ecological status of same by KT methodology, which allows the division of the river system in river segments designated Physiographic Units Homogeneous and identifies the level of their degradation by measuring the local human pressures. From the data obtained may be proposed river restoration measures needed for a "good status" of each ecological unit. The project seeks to achieve the objectives of international conventions to protect the environment and achieve the goals of the Water Framework Directive. This paper develops a synthetic letter exposing the state of conservation of the segments of the river basins of the Hawk and Ribeira da Mata da Ribeira (Ribeira region of West, Central Coast of Portugal), characterizing and quantifying the level of degradation, identifying their respective causes and proposing solutions.
