Geometry of obstacle marks at instream boulders—integration of laboratory investigations and field observations
Sign Up to like & getrecommendations! Published in 2021 at "Earth Surface Processes and Landforms"
DOI: 10.1002/esp.5055
Abstract: Obstacle marks are instream bedforms, typically composed of an upstream frontal scour hole and a downstream sediment accumulation in the vicinity of an obstacle. Local scouring at infrastructure (e.g. bridge piers) is a well‐studied phenomenon… read more here.

DOI: 10.1002/rra.3321
Abstract: River Res Applic. 2018;1–11. Abstract In the Intermountain West, USA, fry of fall‐spawning brown trout (Salmo trutta) are susceptible to scour‐related mortality because they are still in the gravel during spring snowmelt run‐off events. The… read more here.

DOI: 10.1007/s11069-017-2842-2
Abstract: Scour of sediments around bridge foundations by the stream is the most significant contributing factor for bridge failures. The scour failures tend to occur without prior warning and have led to fatalities and economic loss… read more here.

DOI: 10.1007/s13349-020-00420-5
Abstract: One of the most prevalent causes of bridge failure around the world is “scour”—the gradual erosion of soil around a bridge foundation due to fast-flowing water. A reliable technique for monitoring scour would help bridge… read more here.

DOI: 10.1016/j.compgeo.2019.02.028
Abstract: Abstract Scour is a process of soil erosion around foundations caused by currents and waves, which can severely compromise the performance of the foundations. The scour process forms a scour hole around the foundation. The… read more here.
