Abstract Based on artificial neural network(ANN)，an identification algorithm of aquifer parameters is proposed according to the observed water heads and flows in seepage field. The practical example of identifying the permeability coefficients of rockmass and concrete curtain is introduced with proposed ANN. The practical application shows that the forecasted water heads approach to observed values while the identified permeability coefficients are introduced to the FEM model.
