Research and Implementation of Parameters Optimization Simulation Environment for Hydrological Models

摘要

For the Hydrological models' complexity, more model parameters, and most parameters are unpredictable as well as errors of observation data in river basin will lead to lots of errors and uncertainties in Hydrological model parameter calibration, Hydrological modeling and forecasting. Therefore, we developed a unified integrated simulation environment of parameter estimation for Hydrological models in Heihe river basin to support the implementation the processes of simulation operation, parameter optimization, parameter evaluation, analysis and simulation results visualization of Hydrological models in Heihe river basin. By using long-term monitoring measured data, we validated the hy-drologic models' parameters estimation integrated simulation environment in Xinanjiang Hydrological model. The results showed that research in this paper would reduce complex workload of data collection and program development, and significantly improve accuracy and efficiency for model simulation.
