Random errors in the hydrogeological parameters of a two-layer stratum evaluated by multi-well pumping tests

Аннотация

Random errors in estimates of flow and storage parameters of a two-layer stratum, derived from multi-well pumping test data are examined. It was found that the relative random error with a confidence probability of 0.954 is appreciably less than 100% only for the estimates of aquifer transmissivity, while the estimates of the hydraulic conductivity and the specific yield of the overlying deposits show relative random errors with the same confidence probability in excess of 100%. Therefore, the random errors of parameters are to be given as multiples of the established values.
