Climate change is often predicted to cause a significant perturbation to watershed hydrology. It has been generally associated with negative impacts on natural systems, especially in conjunction with conservation and protection of sensitive ecosystems. In the U.S., spawning habitats of threatened and endangered salmonid species are important areas that are potentially vulnerable to climate chan...

Significant growth in mountain rivers research since 1990 has promoted the concept that canyon-confined have complex topographic features nested from base- to flood-stages due canyon structure and abundant large bed elements. Nesting means literally structures inside of structures. Mathematically, nesting multiple individual repeating patterns exist at different frequency, amplitude, phasing, c...

Geometric modeling of river channel topography is a method design synthesis wherein specific 2D geometric elements topography, such as the bed profile, cross sectional shape, and planform contours, are expressed mathematically in isolation then combined to produce 3D heightmap. We utilized framework synthesize terrains that reveal flow-form-function linkages investigate what roles variability r...

River discharge and width, as essential hydraulic variables hydrological data, play a vital role in influencing the water cycle, driving resulting river topography supporting ecological functioning. Insights into bankfull width at fine spatial resolutions are essential. In this study, 10-m Sentinel-2 multispectral instrument (MSI) imagery digital elevation model (DEM) well situ sediment fused t...
