Parameter optimization in hydrology is an important aspect of developing hydrological models. In this paper, on the base of complex optimize problems with regard to runoff hydrological model parameter identify in water cycle simulation, the development process of optimal algorithm with hydrological models is reviewed. Particularly, the new advance in calculation of hydrological model parameter identification at home and abroad is introduced, such as the simulated annealing algorithm, genetic algorithm, SCE-UA algorithm, SCPSO algorithm and coding based accelerating genetic algorithm, simplex algorithm. The optimal results of several genetic algorithms using amalgamation technology and other several algorithms, which are used usually in Xin＇an River Model, are also compared. It is found that the hybrid accelerating genetic algorithm is the predominant. To build various amalgamation technologies and laws is a way, which, based on systemic research modern optimal method and traditional optimal method, may enhance the capability of parameter optimization algorithms.
