Abstract: 

To evaluate the hydraulic parameters of hard in Iran usually methods like Jacob method are commonly used. But as we know, such methods are not able to evaluate hydraulic parameters of hard aquifers accurately. In this study, using double porosity model of Warren & Root and graphical method of Kruseman & Ridder, three pumping test in hard aquifers (two in Shotori dolomite in Tabas region and one in Asmari limestone near Shiraz) have been interpreted and transmissibility of aquifers, storage coefficient of matrix and fractures, as well as the coefficient of flow exchange between porosities (A) and ratio of fracture capacity and capacity of whole reservoir (?), have been calculated.
Finally, double porosity model has been developed for partially penetrating wells and a computer code has been written in Matlab (5.3) to do all the calculations due to Kruseman & Ridder graphical method for interpreting pumping tests of hard aquifer wells for both fully and partially penetrating wells, automatically.
