Abstract:
1. A non-transitory computer-readable recording medium having instructions recorded thereon configured to perform a method of estimating an amount of groundwater pumped from a well when executed by a computer, the method comprising: inputting a maximum drop threshold (Dmax), a tolerance (tol), a delta time interval (Dt), and a pump capacity (Capacity obtaining sensor data that comprises water head level (HEAD) data points as a function of time in which the sensor data comprises a total number (N making an array of head differences (Dh(i)) between adjacent timed HEAD data points in accordance to Dh(i)=HEAD(i+1)−HEAD(i), wherein i is a counting integer between and including 1 and N setting initially an integer sum to zero (i increasing i advancing i=i+1 after increasing i incrementing i stepping i=i+1 after incrementing i summing it resetting i adjusting Q accumulating i=i+1 after resetting i repeating the steps of increasing, advancing, incrementing, stepping, summing, resetting, adjusting, and accumulating until i+1>N calculating T outputting T
