Abstract
       Pumping test data in karstic aquifers are usually analyzed using conventional methods originally developed for granular aquifers. Theis (1935) and Cooper-Jacob (1946) straight-line methods are the most common conventional methods applied to karstic aquifers. Some investigators have utilized double porosity based methods for analyzing pumping test data in karstic aquifers. However, this question might be raised that which method is the most appropriate for analyzing pumping test data in karstic aquifers. It seems that the most appropriate methods for almost all pumping test data in karstic aquifers are Theis (1935) and Cooper-Jacob (1946) methods. However, methods based on double porosity theory should be applied for some of pumping test data. In this paper, the most appropriate method for analyzing pumping test data in karstic aquifers is addressed based on a number of pumping test data obtained from different karstic area.
