Erosion of Soils and Scour Problems
An erosion problem always has three components: the soil or rock, the water, and the geometry of the obstacle that the water is interacting with. Erosion categories are proposed to bring erodibility down in complexity from an erosion rate vs. shear stress function to a category number. Soil erosion is not very well known, but rock erosion is even less known, so the engineer must exercise a great deal of engineering judgment when it comes to rock erosion. This chapter shows the profile of water velocity as a function of flow depth. Bridge scour refers to the erosion of the soil surrounding the foundation of bridge piers in rivers. Rivers are active system where meanders can move laterally several meters per year. This lateral migration of the main channel affects bridges, embankments, and other structures straddling the river. It is important to predict future meander movements to design remedial measures or move the structure.
