摘要：Abstract The increased sensitivity for the preservation of the riparian ecosystems equilibrium has guided the attention of researchers and planners towards river restoration interventions, to give a higher naturalness to watercourses. Interventions of ecological river restoration in urbanized areas require specific preliminary studies and surveys on the hydraulic compatibility of materials (both living and nonliving) and works, in order to verify the effects induced by the new fluvial settlements on the hydraulic safety of riverbed reaches and its surroundings. In this work three contexts will be identified: three representative contexts in an urban environment, and, for each of them, possible ecological river restoration interventions will be proposed.
