A generalized graphical method for evaluating formation constants and summarizing well‐field history

The capacities of a water‐bearing formation to transmit water under a hydraulic gradient and to yield water from storage when the water table or artesian pressure declines, are generally expressed, respectively, in terms of a coefficient of transmissibility and a coefficient of storage. Determinations of these two constants are almost always involved in quantitative studies of ground‐water problems.
