This lecture by the instructor covers the eco-morphology of rivers, focusing on the revitalization of watercourses, hydraulic construction platforms, and the classification of natural rivers. It delves into the assessment of the ecological state of watercourses and the preparation for practical group work. The lecture emphasizes the importance of understanding the drivers of ecological integrity and the methods used for river assessment and classification. Examples are provided to illustrate the various activities involved in river restoration projects, highlighting the need for effective success control. The lecture also discusses the impact of different stressors on ecological integrity, such as connectivity interruption, river fragmentation, hydropeaking, altered sediment regimes, and species pool extinction.
