Coastal and Floodplain Construction Inspector's Practice Exam

What is the term for the widespread loss of soil in coastal construction?

1. Scour

2. Erosion

3. Deposition

4. Soil degradation

The correct answer is: Erosion

The term "erosion" is correct in describing the widespread loss of soil in coastal construction. Erosion refers to the process by which soil, rock, or sediment is removed from one location and transported to another, typically by wind, water, or ice. In coastal areas, natural forces such as waves, tides, and currents can significantly contribute to the erosion of coastlines, leading to the loss of land and affecting construction stability. This process can be accelerated by human activities, such as the removal of vegetation, alteration of water flow, or construction practices that disturb soil. Understanding erosion is vital for coastal and floodplain construction because it informs engineers and builders on how to mitigate these effects through proper design and planning. The other terms listed do not accurately describe the widespread loss of soil in this context. For instance, "scour" usually refers to the removal of sediment from around structures due to water flow but is not as broad as erosion. "Deposition" describes the process where sediment settles and accumulates, leading to the creation of new landforms rather than loss. "Soil degradation" typically refers to the deterioration of soil quality and function, which can include loss of nutrients or soil structure but does not directly indicate widespread soil loss across an
