Soil Profile Evolution and Erosion in Forested Watersheds - Illustrated Diagram #303454 (License: Personal Use)

This three-panel illustration depicts the chronological evolution of a forested watershed’s soil profile under erosive forces: Stage I shows an undisturbed profile with distinct horizons (O-W, M, S, Bm, Bs, Bf, MF); Stage II reveals incipient gully formation and horizon truncation; Stage III displays advanced erosion with loss of upper horizons and deepening of the channel, altering vegetation patterns and soil structure.

Used in academic textbooks, environmental science courses, and land management resources to explain soil degradation, watershed dynamics, and conservation planning; targets students, researchers, and ecologists seeking visual understanding of geomorphic processes.
