Abstract
A method of measuring a pumping amount of groundwater by using water level fluctuation, a water level measuring sensor including an arithmetic operation unit for calculating a pumping amount by using the method, and a computer-readable recording medium having recorded thereon a program for executing the method are disclosed. The method includes: obtaining groundwater level data according to a measurement time by measuring fluctuation of a groundwater level for a predetermined period continually at time intervals; comparing groundwater level formed in a full pumping period including an initial stage a quasi-balance period, and a recovery period calculates a total time when pumping has been performed, by using a measurement time of the sorted data; and calculates a total pumping amount by using the total pumping time calculated.
