Abstract
An apparatus for measuring a flow velocity and a flow rate of groundwater leaking from the earth surface includes: a storage tank that is fixed to close a side surface and a top surface of an earth surface region from which the groundwater leaks and that stores the groundwater leaking from the earth surface; a liquid column tube that causes the groundwater stored in the storage tank to introduce thereto and causes a water column to rise; and a pressure-type measuring unit that is formed in a top opening of the liquid column tube and that senses a differential pressure. Accordingly, it is possible to easily and rapidly measure a flow velocity and a flow rate of groundwater leaking from the earth surface by the use of a user's terminal in real time, or by time zones, or on the user's request.
