Method of artificial neural network in groundwater quality evaluation

By the theory and method of artificial neural network, a BP neural network model in groundwater quality evaluation is presented, with which groundwater quality in GuoBei mine is evaluated and compared with the classification of grey theory.The result indicates that the BP neural network model can resolve primely complicated nonlinear relation between evaluating gene and water quality grade,and the method is convenient,reliable and precise, so it can be used commonly and objectively.
