Critical flow theory and wave trainsÂ
Critical flow theory and wave trainsÂ
We are investigating Critical Flow Theory using a combination of flume and remotely sensed data analyses. We focus these studies in undular hydraulic jumps or "wave trains" as they are commonly referred to by whitewater enthusiasts. This is an ongoing project and we are currently looking for interested graduate students to contribute to this research.
Influence of floodplain vegetation on meandering channel morphodynamics
Influence of floodplain vegetation on meandering channel morphodynamics
We use physical and numerical modeling experiments to investigate the influence of rigid emergent vegetation on meandering channel hydraulics and bed topography. At the CSU hydraulics lab, we simulated various floodplain cover scenarios and found that increased floodplain vegetation density produced stronger in-channel secondary flow and complex bed topography. We are currently expanding this research to investigate the influence of floodplain vegetation on aquatic habitat suitability.
Post-fire river corridor response
Post-fire river corridor response
The Cameron Peak Fire burned over 200,000 acres of the Cache la Poudre River Watershed in 2020. Since then, we have been monitoring hydrology, channel morphology, and vegetation response in headwater catchments that feed the Poudre River. Through this research, we hope to inform management decisions at reach to watershed scales both at this site and other mountainous regions where catastrophic wildfires occur.
