Potholes contribute to erosion and widening of river channels, altering the landscape over time. Can potholes be used as indicators of past environmental conditions? Yes, the presence of potholes can provide insights into past river dynamics, flow rates, and sediment characteristics.

In Earth science, a pothole is a smooth, bowl-shaped or cylindrical hollow, generally deeper than wide, found carved into the rocky bed of a watercourse. Other names used for riverine potholes are pot , (stream) kettle , giant's kettle , evorsion , hollow , rock mill …

Potholes are round/oval shaped holes in the bedrock of a river bed. Potholes on the River Ure, close to Ayesgarth Falls. They are formed when sediment and other material carried by a river scour the bed. Where depressions exist in the channel floor turbulent flow can cause pebbles to spin around and erode hollows through abrasion/corraision.

2018年10月1日 · Knowledge of the pothole depth–diameter relationship is useful in a number of contexts, including simulation of hydraulic dynamics, theoretical considerations of erosion, comprehension of channel incision and development of canyons and gorges, and accurate estimation of excavation volume and mechanical strength of potholed bedrock in the design ...

Potholes can form when water collects on a layer of exposed rock. Windblown particles, flowing water from rain, freezing and thawing can cause slight erosion of the surface. When water is present, bacteria, fungi and algae play a greater role in …

2009年9月1日 · Pothole evolution reflects the hydrodynamics of the erosion, by high velocity flood flows, of bedrock. They evolve in time and in concert with the evolution of the landscape.

2006年12月6日 · Erosion within potholes is complexly related to erosion on the adjacent bed. Erosion efficiencies within small, hemispherical potholes must be high if the potholes are to survive in the face of bed translation (incision). As potholes deepen, however, the necessary efficiencies decline rapidly.

2006年12月6日 · Flow within a pothole removes a greater volume of substrate than does flow across adjacent surfaces; therefore, the efficiency of erosion within a pothole is an important measure of the ability of the pothole to erode the channel bed …

2017年3月7日 · Potholes dynamic changes on the river bed and follow two main parameters; radius and depth. Potholes central inner radius develops rapidly compared to the vertical erosion at the base of the potholes. Potholes dynamic growth of …

2009年9月1日 · The capacity of fluvial potholes to trap sediments, together with the geochemical analysis of their stored sediments for environmental assessment, is an overlooked research topic in small bedrock...
