Calculation of aquifer parameters and its evaluation of groundwater-bearing during steady flow pumping

As for some questions about obtaining the aquifer parameters using steady flow pumping in single well,three different aquifer parameters,which reflect real values approximately,are obtained through the data of pumping recovery section after analyzing hydrogeological condition of loose aquifers in Cenozoic.By the way of multivariate regression,the relationship between drawdown and discharge is gotten and,according to the values of different coefficients,the extent of water-bearing of three aquifers is deduced indirectly,which provides some reference for groundwater exploration.
