In shallow conduit flow (SCF) carbonate aquifers, the nature of the void space and groundwater flow differs from that of granular aquifers in that the voids are solution conduits, often of large size, and flow is generally non‐Darcy. These and other characteristics of SCF aquifers preclude the application of pumping test analysis methods based on the diffusion equation. The drawdown interval analysis (DIA) method, which is consistent with a conceptual model of the SCF aquifer, provides estimates of aquifer parameters using both direct calculation and simulation approaches. Application of the DIA method to two wells yielded parameter values which are consistent with the hydrogeologic setting of the wells.
