Scour refers to the process of cleaning or removing dirt and debris from a surface, often using a scrubbing action. This technique is commonly applied in household cleaning, such as washing dishes or scrubbing floors, to achieve a spotless finish. Scouring agents, like scouring pads or abrasive cleaners, are often used to enhance the cleaning effect. In a geological context, scour describes the erosion of soil or sediment caused by flowing water, such as rivers or streams. This natural process can shape landscapes and create features like riverbanks and gorges. Scour can also impact infrastructure, leading to concerns about the stability of structures like bridges and dams.
