Soil Infiltration Diagram: Understanding Water Percolation Through Layers #125969 (License: Personal Use)

This schematic illustrates the process of water infiltration, where surface runoff enters the ground, passes through a porous sandy soil layer, then a coarser gravel stratum, and finally flows laterally as groundwater. Arrows indicate both vertical percolation and horizontal subsurface movement, highlighting key concepts in hydrogeology and sustainable drainage design.

Used in educational materials, environmental science textbooks, civil engineering guides, and stormwater management resources to explain infiltration, aquifer recharge, and low-impact development practices.
