Rachel G. Gidley and colleagues investigate sediment movement and changing stream channels in Colorado's Stinking Water Creek Basin. The report compares subbasins with different land uses, bringing together evidence about grazing, energy development, channel incision and the chemistry of sediment within a shared watershed.
Historical aerial photographs provide a longer view of landscape change, while field surveys and uncrewed aircraft surveys document present channel forms. Sediment sampling, dating and density measurements add further ways to examine how material has accumulated and moved through the basin.
The study connects observations across different timescales rather than relying on a single snapshot of erosion. Maps, photographs, measurements and analytical results show how the authors reconstruct the development of the arroyo system and compare conditions among its subbasins. The result is a detailed environmental case study for readers interested in geomorphology, land-use history and sediment transport in semiarid landscapes.
