Abstract
Water flow in soils is fundamental to subsurface hydrology, biogeochemical cycling, contaminant transport, and ecosystem services. It has taken three centuries for three principles of water flow in soils to be identified. The first came to light in the 19th century, known as the Darcy's law. The second was formally proposed by L.A. Richards in the 20th century. The third principle is emerging in the 21st century, where a combined macroscopic and microscopic consideration portrays complex preferential flow networks embedded in heterogeneous soils. This 3rd principle is presented and illustrated in this paper.
