Abstract:Groundwater drawdown is typically measured using pumping tests and eld experiments; however, the traditional methods are time-consuming and costly when applied to extensive areas. In this research, a methodology is introduced based on arti cial neural network (ANN)s and eld measurements in an alluvial aquifer in the north of Iran. First, the annual drawdown as the output of the ANN models in 250 piezometric wells was measured, and the data were divided into three categories of training data, cross-validation d… Show more
