“See” groundwater flow by using a Hele-Shaw cell. The Hele-Shaw cell consists of two parallel transparent walls with a small gap between them that is filled with a viscous liquid that moves in response to a pressure difference along the plates. The pattern of flow between the walls of the cell is equivalent to groundwater flow in a plane. This video shows surficial recharge to groundwater that discharges to water bodies on both sides.

A discussion of the material in this video provided in Section 2.6 “The “Hear See Do” of Flow Nets” of the Groundwater Project book “Graphical Construction of Groundwater Flow Nets”. Section 2.6 can be read online, or the entire book can be read online or a PDF of the book can be downloaded.
