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.
09/08/25 Congratulations, Kayla Schultz and Brady Jones!
One June 10, Kayla successfully passed her MS defense in a packed room of friends, family, and collaborators. In her research, Kayla studied three headwater tributary sites in the Kawuneeche Valley in Rocky Mountain National Park to observe the impacts of the loss of beaver dams on floodplain connectivity.
And on August 26, Brady successfully passed his MS defense on using low-technology process-based restoration (LTPBR) to reestablish natural riverine processes post-wildfire. He studied Elkhorn Creek, the headwaters of the Cache la Poudre River, to quantify the affects of LTPBR on sediment accumulation and groundwater storage.
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.
