Comparison of experimental pumptest data with this theoretical curve by graphical means has been a standard method of determining aquifer transmissivity and storage. Through the years, the Theis equation has played an important role in groundwater hydrology. The method is not universally applicable to all pumping tests, but has been designed to analyze data conforming to assumptions implicit in the Theis equation. The method also gives an indication of how well it could analyze the data. The automated analysis has the advantage that it is always objective and cannot consider any personal bias. However, access to a computer capable of using the FORTRAN language is necessary. The method is simple, quick, and inexpensive. Some means of automating the analysis of these pumping tests would be desirable. Undoubtedly, many more pumping tests will be made in the future. Many pumping tests have been made through the years to help determine the aquifer transmissivity and storage coefficient (transmissivity is a measure of how easily water flows through the earth and the storage coefficient is a measure of how much water is stored per unit volume).

It is clear that computer storage and manipulation are necessary to make full use of the data. The data base is massive and still is not complete. Much money and effort are expended each year to collect various kinds of data. Water is a valuable resource of the State of Kansas. This is, in general, the original text as published.
