This course introduces key concepts pertinent to understanding rivers and stream ecosystems and their management in the face of multiple human stressors acting at local through landscape scales. Physical, chemical and biological aspects are integrated into a holistic understanding of the processes that maintain the variety and variability of fluvial ecosystems. Using the watershed as a framework, the impacts of human activities are described and possible management and restoration actions are explored. Management issues including threats to river health, evaluation methods, management and restoration are covered in depth. Appropriate both for students interested in conducting research in fluvial ecosystems and for those interested in management of rivers and their watersheds. Need not be taken concurrently with NRE 521.
