Section 4: Soil and Water Conservation Engineering

Soil and Water Erosion

Subtopic: Mechanics of soil erosion – wind and water erosion

Question Statement:

The progressive stages of water erosion in order of increasing severity are:

Options:

  • (A) Splash erosion $\to$ Sheet erosion $\to$ Rill erosion $\to$ Gully erosion
  • (B) Sheet erosion $\to$ Splash erosion $\to$ Gully erosion $\to$ Rill erosion
  • (C) Rill erosion $\to$ Gully erosion $\to$ Sheet erosion $\to$ Splash erosion
  • (D) Gully erosion $\to$ Rill erosion $\to$ Sheet erosion $\to$ Splash erosion

Answer Key:

A

Step-by-Step Solution & Explanation

Water erosion begins with raindrop impact (splash erosion), progresses to thin uniform surface removal (sheet erosion), concentrates into microscopic channels (rill erosion), and deepens into impassable channels (gully erosion).
