Changes in water chemistry and fluvial geomorphology from arsenic contaminated floodplains of Whitewood Creek and Belle Fourche River, South Dakota
… investigated the changes in the tailings and fluvial geomorphology of Whitewood Creek and the Belle Fourche River from 1948 to 2012. This was performed by using aerial photographs from 1971, which mapped locations of the tailings along the floodplains, and overlaying them with photographs from …

Searching for the ideal river? New directions in geographical geomorphology
Geomorphology’s development as a scientific subject has produced increasingly sophisticated insight into the physical processes shaping the earth’s surface. It is increasingly apparent, however, that understanding contemporary environments requires equal attention to the processes through which …

The Influence of Bank Vegetation on Flow Structure Within a Small Agricultural Stream: Implications for Channel Stability
… channel form. Although past studies in fluvial geomorphology have largely ignored the complicated role ofinstream and bank vegetation, some recent studies have attempted to characterize flow in vegetated environments. There is, however, still a need to examine the influence of bank …

Sediment Control In Alluvial Rivers Using Simulation-Based Optimization
… and cause changes in flow characteristics and fluvial geomorphology. Severe sediment erosion such as in-stream sever bed and bank erosion or gullying can threaten the stability of in-stream hydraulic structures, river banks, levees, and underground utilities. On the other hand, large amounts of …

Conceptualizing Anthropogenic Change in Fluvial Systems: Drainage Development on the Upper Embarras River, Illinois
… into aspects of physical geography, specifically fluvial geomorphology, from both a conceptual and pragmatic point of view. The upper Embarras River in east central Illinois was utilized as an example of how such an approach can be utilized for a greater understanding of anthropogenically modified …

Classifying Single-thread Rivers: A European perspective
… rivers, which are free to adjust to fluvial processes. The research involves subdividing rivers along a continuum of geomorphological characteristics to assign river reaches to geomorphologically-meaningful classes according to their channel dimensions and forms, and floodplain …

Numerical modeling of river migration incorporating erosional and depositional bank processes
… of the scientific community, in the fields of fluvial geomorphology, hydraulic engineering and river restoration. Several meander evolution models developed over the years have provided a deeper insight into meander dynamics. In almost all these models however, a river width that remains …

Interaction of Clay Wash Load With Gravel Beds
… been well examined. A fundamental assumption in fluvial geomorphology and river engineering is that wash load particles ($d<63mu m$) do not deposit to stream beds, but are instead transported downstream until they deposit in reservoirs or estuaries. The goal of this study is to determine if wash …

Channel Migration and Bank Erosion of the Clark Fork River at Grant-Kohrs Ranch N.H.S., Western Montana
Large-scale mining, concentration and smelting in Butte and Anaconda, Montana over the last c.a. 150 years led to contaminated tailings being distributed along the entire upper Clark Fork River System. The extent of hazardous material distributed along the Clark Fork River is a major concern …
