Flagstaff Scientists Look to Drones

By Southwest Biological Science Center March 16, 2017

The Arizona Daily Sun published a piece about the use of unmanned aircraft systems (UAS) by USGS researchers in Flagstaff.

The Arizona Daily Sun published a piece about the use of unmanned aircraft systems (UAS) by USGS researchers in Flagstaff. Joel Sankey (SBSC) and John Vogel (WGSC) discussed the mapping of sandbars and river terraces along the Colorado River in Grand Canyon in the article. Additionally, the use of UAS in SBSC biocrust research and floodwaters research by the AZ Water Science Center were mentioned in the article.

Connectivity of Sand Resources Along the Colorado River in Grand Canyon

We study the links among different geomorphic processes that affect river valley landscapes in the Colorado River downstream from Glen Canyon Dam, Arizona. Dam-released flows affect the deposition and retention of sandbars that serve as sources for other sand resources, such as windblown sand dunes, throughout the Colorado River ecosystem. The degree to which the landscapes are differentially...

Grand Canyon Sandbar Monitoring

Since the completion of Glen Canyon Dam in 1963, the amount of sand supplied to Grand Canyon National Park has been reduced by more than 90 percent. The Paria River, a tributary to the Colorado River 15 miles downstream from the dam, is now the single most important supplier of sand to the Colorado River within the Park. This large reduction in sand supply has resulted in substantial decrease in...
