CURRENT RESEARCH PROJECTS


Colorado River Projects

1) Development of a Management Tool for predicting Multi-Dimensional Sand-Bar Evolution and 1-Dimensional Sand Transport in the Colorado River Ecosystem

2) Long-Term Monitoring of Fine-Grained Sediment Storage throughout the Main Channel of the Colorado River Ecosystem

We are monitoring the magnitude and style of sand storage in Marble and Grand Canyons using recent advances in bathymetric and GIS technology; interpreting observed changes in a historical context based on analysis of multitemporal aerial photographs; and characterizing the longitudinal organization of sand storage in Grand Canyon. We are also developing a sand storage and sediment transport model for the Canyon. Collaborators are Steve Wiele, David Rubin, and David Topping of the USGS. Funding is provided by the Grand Canyon Monitoring Research Center.

Green River Projects

The Role of Riparian Vegetation in Determining Channel Form along the Green River in Dinosaur National Monument in Colorado

To assess the effects of tamarisk removal on geomorphology in the Canyon of Lodore, we have collected detailed topographic data within tamarisk removal and control reaches and developed 3-dimensional models of sandbar topography. David Cooper of Colorado State University is a collaborator on this project, and funding is provided by the US Dept. of Interior through the Bureau of Reclamation and the Central Utah Project Completion Act Office.

Duchesne River

Analysis of Channel Stability and Sediment Transport on the Duchesne River in Utah

Graduate student Dave Gaeuman is integrating historical geomorphology with existing methods for specifying in-stream flow requirements for habitat and channel maintenance on the lower Duchesne River. This project is funded by the US Fish and Wildlife Service.
