River Restoration Strategies in Oregon: ES407 Senior Seminar Working Group

Explore the efforts of the ES407 Senior Seminar Working Group from Western Oregon University in Monmouth as they delve into river restoration strategies, watershed assessment, salmonid habitat restoration, fluvial hydrology, and more. Discover the historical framework shaping modern interventions and the most common remedial actions employed to improve hydrologic, geomorphic, and ecological processes in Oregon rivers. Engage with a diverse range of topics through session overviews and delve into the significance of riparian vegetation, fish passage, and channel modification in restoring aquatic ecosystems. A five-minute river interlude provides a visual journey into salmon spawning dynamics.
