Garden with Insight v1.0 Help: lateral subsurface flow

Lateral subsurface flow is the flow of water through the soil horizontally (or at a slope) through soil pore spaces (the larger macropores). If you think of soil like a sponge, lateral flow is like what happens if you place one sponge next to another on a sloping surface: some of the water moves into the other sponge.

In this simulation lateral flow depends on saturated conductivity, field capacity, porosity, soil water content, and the soil patch's slope.

How it works:
