11/7/2025 Research Group Attends the 79th Annual Meeting of the Rocky Mountain Hydrologic Research Center
The research group drove to Boulder, Colorado, to attend the Rocky Mountain Hydrologic Research Center’s annual meeting. Aleah Hahn, who received a scholarship from RMHRC, was an invited speaker and presented. Nicholas Christensen also gave a presentation on his latest work on flood attenuation at network scales. The conference was a great way to connect with other river-focused researchers across the Front Range, and we’ll see them again in 2026!
9/10/25 Aleah Hahn Receives Scholarships to Support Data Extension and Dissemination
Aleah Hahn recently received two scholarships. The first is is a Rocky Mountain Hydrologic Research Center (RMHRC) Supplemental Research Funding award. The funds will support expanding Aleah’s dataset to examine if her findings about log jams could extend to differently sized rivers across Colorado.
The second is a runner-up award from the Colorado Riparian Association. The scholarship will support Aleah’s graduate studies and allow her to attend the Sustaining Colorado Watersheds Conference in 2026 and present her research to the association.
10/6/2025 Research Group Attends the 7th International Symposium on River Science
Several research group members traveled to UC Davis to attend the International Symposium on River Science. Steve Griffin, Mariah Papac, Nicholas Christensen, Aleah Hahn, and I gave presentations on topics ranging from flood attenuation at network scales to the role of beavers in improving floodplain connectivity. The symposium was a great chance to reconnect with river scientists from around the world. The next ISRS conference will be held in Cape Town, South Africa in 2027!
Rivers and floodplains are complex, resilient systems that have been altered around the world.
My research focuses on understanding the complexities of river systems, the impacts of human alterations, the importance of river restoration.
