Parameter Sensitivity Analysis Method and Application in the Haihe River Basin
Parameter sensitivity analysis is the important and difficult problem in the application and development of distributed hydrological model. The paper discusses the develop trend from local sensitivity analysis to globe sensitivity analysis method, applies LH-OAT method to above Nanzhuang hydrologic station in the Haihe River Basin, the most sensitive parameter is found. LH-OAT method combines the robustness of the Latin Hypercube sampling and the efficient of the OAT method, the result is more reliable. Through calibrate parameter, Nash efficiency coefficient increases significantly. In the end, the development direction of parameter sensitivity analysis is prospected.
