| Abstract: | This paper takes three-dimensional unsteady state flows in an inhomogeneous, isotropic confined aquifer as an ideal model, and discusses the application of genetic algorithm to an inverse problem of hydrogeologic parameters. Based on the calculation results it has been proved that the best chromosome clone plus younger generation chromosome prepotency genetic algorithms, which are developed and based on simple genetic algorithms, has faster convergence rate, higher accurate solutions. Since this research is based on finite element method, the algorithm presented in this paper has vast vistas for groundwater resources evaluation and mine dewatering calculation. |
