What is ground scouring?

Ground scouring is a process in which flowing water erodes or removes soil or sediment from the surface of the ground. It can occur naturally, such as in the formation of canyons or river valleys, or as a result of human activity like construction or damming. Ground scouring can pose a serious threat to infrastructure, particularly bridges and other structures built over water, if it undermines the stability of their foundations. It can also cause environmental damage, such as the loss of habitats for aquatic animals or the contamination of waterways by sediment and other pollutants. Engineers and planners take measures to prevent ground scouring through careful design and construction techniques, including the use of erosion control measures like riprap or gabions.
