In this study, a novel estimation method, called as Ratio Matching Process (RMP), was proposed to determine the hydrologic parameters of a leaky strip aquifer. RMP employs two simple formulations in order to simplify the parameter estimation procedure. The first formula gives the leakage factor from the site data by selecting two different time- drawdown measurements, which are separated by the user-specified distance from the inflection point of the drawdown vs logarithmic time curve. The second formula provides the users to find the dimensionless inflection point from the leakage factor. Thus, the aquifer parameters could be easily acquired with RMP by avoiding the classical curve matching process. The capability of RMP was studied with several hypothetical pumping test scenarios including ideal and noise- contaminated datasets. The results from the implemented cases indicate that RMP can be regarded as a good alternative to the available methods.
