PyTheis—A Python Tool for Analyzing Pump Test Data

The Theis equation is an important mathematical model used for analyzing drawdown data obtained from pumping tests to estimate aquifer parameters. Since the a nonlinear equation, complex graphical procedure employed fitting this pump test data. This method was originally proposed by in late 1930s, and since then, all groundwater textbooks have included method. Over past 90 years, every hydrologist has been trained use tedious estimating values of transmissivity (T) storage coefficient (S). Unfortunately, mechanical does not provide any intuition understanding inherent limitations manual procedure. Furthermore, it parameter error. In study, we employ public domain coding platform Python develop script, namely, PyTheis, which can be simultaneously evaluate T S values, error associated with these two We solve nine problems demonstrate robustness script. include several published case studies that real field Our show script efficiently variety problems. code also easily adapted other hydrological require curve routines.
