Development of Artificial Intelligence Committee Machine for Transmissivity Estimation, Case study:Tasuj Plain

Hydrogeological parameters like transmissivity are among the important and money-consuming input parameters of ground water modeling. Fuzzy logic, Artificial Neural Networks, and Neurofuzzy has high capability in hydrogeological parameter estimation.In this research combination of these models applied to transmissivity estimation of Tasuj aquifer. Tasuj plain aquifer is one of the marginal plains of Lake Urmia which suffered more ground water declination in last decades and needs qualitative and quantitative management. To overcome the complexity of hydrogeologic systems, Hybrid Artificial Intelligence Modelis then presented as a committee machine. Based on the outputs, weights of each models optimized using particle swarm optimization which caused to form committee machine. Related geophysical and hydrogeological variables to transmissivity such as transverse resistivity (Rt), electric conductivity (EC), alluvium thickness (B), and geographic location were among inputs to this study. The obtained results from presented committee machine showed higher efficiency compared to the Fuzzy logic, Artificial Neural Network, and Neurofuzzy models, individually.
