Q

Scouring usually occurs with soils such as __________.

🔍 Key Concepts

• Scour refers to erosion of soil around an anchor, pile, or structure due to water movement • Different soil types (sand, mud, clay, coral) have different resistance to being washed away • Think about which soils are most easily displaced by currents or propeller wash

💭 Think About

• When strong current or propeller wash acts on the bottom, which soil type is most likely to be carried away quickly? • Which of these bottom types tends to be loose and granular rather than sticky or cemented together? • On which type of bottom would you worry more about an anchor or pile becoming exposed over time due to erosion?

✅ Before You Answer

• Be clear on what scouring means: removal of material by moving water • Compare how tightly the particles are bound: loose grains vs cohesive (sticky) soils • Eliminate any bottom types that are naturally very hard or cemented and unlikely to wash away easily
