Environmental Science Capstone Projects

Students develop a written proposal during the fall quarter and then a final project report during spring quarter.

Examples of Recent Projects

For each project, a professional liaison from a sponsoring organization works with a team of three to five students and a faculty advisor over the course of an academic year. Projects have been supported by groups such as King County, Seattle City Light, Seattle Public Utilities, and the Northwest Avalanche Center.

The Impacts of Pond Levelers on Beaver Dam Overtopping and Fish Passage

Sponsor:  Snoqualmie Valley Watershed Improvement District

Description: This project explored the impacts of pond levelers on beaver dam overtopping and fish passage.  Through fieldwork, data collection and research, students assessed the ability of fish to pass through beaver dams by analyzing overtopping frequency, required leap heights, and water depth at four sites in King County.

Evaluating the Use of Large Wood in Duwamish River Salmon Habitat Restoration

Sponsored by the USDA Forest Service, the team evaluated the use of large wood for restoration in the Lower Duwamish River. They conducted a field survey and inventoried the size, location, placement, and elevation of natural and implemented wood. They made recommendations as to the benefits of future studies that focus on the use of large wood in non-industrialized estuaries.

Watershed Hydrology Modeling, Rio Ochomogo, Nicaragua

In collaboration with students from the University of Central America, the team installed a gage on Rio Ochomogo, a tributary to Lake Nicaragua that has been identified as a significant source of sediment and agricultural pollutants.  The team developed a relationship between flow and water level at the site and developed a three-month long record of river discharge.  The team also created a numerical model for runoff and sediment production using the Soil and Water Assessment Tool (SWAT).

Identifying and Mapping Non-Native Maples Near Newhalem, Washington

Sponsored by Seattle City Light, the team mapped non-native trees that have colonized portions of the riparian area along the Skagit River near the town of Newhalem, Washington. The team evaluated the ecological impact of non-native species in various habitat types, considering dispersal distances and colonization pathways of the major non-native species. It also included a discussion of management implications and possible controls.
