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
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).
