Based on improved particle swarm optimization(IPSO),and the study of the nonlinear-dynamic identification of Elman neural network,a new algorithm was presented,in which IPSO algorithm was combined with the Elman network.

By analysing the characteristies of groundwater parameter,the dynamic thought is intro-duced to groundwater parameter identification,and then,a method of groundwaterparameter dynamic identification is proposed.
