A method to identify aquifer transmissivity, storativity and natural recharge (inverse modeling), based on a geostatistical approach is presented. The basic assumptions of the method are briefly dicussed, followed by an outline of its application to two case studies: the Avra Valley aquifer in Arizona, USA, and the Israeli Coastal Aquifer. Application of the method led to estimates of the natural recharge and storativity, detailed maps of transmissivity and head and to confidence intervals for these variables.
