SOURCE 2022 has ended
The mission of the Symposium of University Research and Creative Expression (SOURCE) is to provide a university-wide forum for Central Washington University (CWU) students, encouraging equity, diversity, and inclusivity, representing all disciplines and experience levels, to present their mentored research, scholarship, and creative works in a juried environment that meets professional conference standards and expectations.

The 2022 SOURCE program is hybrid. Pre-recorded virtual talks are colored green and can be watched anytime. Live/in-person sessions with Zoom access can be found in the daily schedule. Thank you for joining us!

We measured cross sections of Reecer Creek at three locations in the Reecer Creek Floodplain Restoration Project in Ellensburg, WA. The significance of this project is to fully understand the natural dimensions of Reecer Creek, and identify channel stability, the channel migration zone, and channel beds. Ongoing variations in water flow in the Reecer Creek flood plain have led to corresponding variations in the topography of the river bed, due to both deposition of organic material, and erosion due to water flow. We took depth measurements of the river bed every quarter-meter to create a graphable cross-section of three different locations along Reecer Creek. We compared our data to two cross sections taken since 2011. We found a reduction of depth indicating a pattern of deposition, raising the height of the river bed across most points of observation. We conclude that two of the cross-sections were narrower and one was morphed into a wetland adjacent to the main channel. This is most likely the result of the floodplain added in 2011 to stop flooding within the housing community surrounding the area. This changed the ecosystem and environment within the streams dramatically and may continue to change in upcoming years.
