Underground engineering for mining, petroleum, geothermal reserves, nuclear waste storage and dams is mainly conducted in fractured rocks. Understanding the hydraulic behavior of the rock mass is essential because the fractures are assumed to be the main fluid paths in the rock mass. In this paper, the hydraulic behavior of the rock mass was simulated based on the neighborhood elements condition using the Cellular Automata method. This method has numerous capabilities in the simulation of complex physical phenomena such as fluid flow through fractured rock. The Cellular Automata method was used to build channel networks in jointed rocks to estimate water flow into underground openings. To validate the proposed model the transformer cavern inflow of the Siahbisheh power station was numerically calculated and compared with associated measured values. Using the cellular automata, the channel network and conductive fracture of flow were determined. Then the flow rate into the cavern was calculated. The results of the Cellular Automata method were compared with measured data and the results of formerly analyzed statistical method. It is concluded that the Cellular Automata method error is quantitative. The results shown that the statistical methods estimated a higher inflow rate than the measured rate, and their errors were greater than those from the Cellular Automata method.
