Subsurface Flow
Subsurface flow refers to the movement of water beneath the Earth's surface, typically through soil and rock layers. This process occurs when rain or surface water infiltrates the ground, following the natural pathways created by porous materials. Subsurface flow is crucial for replenishing aquifers, supporting plant roots, and maintaining groundwater levels. It can occur slowly or quickly depending on soil permeability and other conditions. Understanding this flow helps manage water resources, predict flooding, and prevent contamination of underground water supplies.
