Wind Erosion and Dust Emissions on the Colorado Plateau

Wind erosion of soils and dust emissions are a significant resource management challenge on the Colorado Plateau. Loss of topsoil and associated aeolian sediment (wind-driven sediment) movement can lead to reduced soil fertility as well as abrasion and burial of vegetation. Dust in the atmosphere poses a threat to human health, visual resources, and regional water supplies (due to interactions...

Measuring Suspended-Sediment Concentrations, Grain Sizes, and Bedload using Multiple Single-Frequency Acoustic Doppler Profilers and Echologgers in the Lower Chippewa River, Wisconsin.

The Upper Mississippi River (UMR) provides critical habitat for hundreds of aquatic species and provides Minnesota with a transportation link to the rest of the world. Reliable measurements of sediment are important for making decisions as part of maintaining the channel. In 2014, sediment deposition in the navigation channel caused channel closures of the UMR delaying commercial navigation...
