To provide a groundwater flow conservation method which enables the design of water passage facilities to be properly performed by means of an equivalent coefficient of permeability giving consideration to a groundwater flow to the water passage facilities, and which enables the suitable securement of the groundwater flow.
In this groundwater flow conservation method, groundwater blocked by an underground structure 3 passes through the water passage facilities 4 which is installed in the underground structure 3, so that the groundwater flow is secured. The equivalent coefficient of permeability, which is set by replacing the whole underground structure 3, including the water passage facilities 4, with a material having equivalent water permeability, is set by means of an equivalent permeability coefficient calculation formula giving consideration to the groundwater flow to the water passage facilities 4.
