  1. Partition Calibration Strategy for A Fully-Coupled Hydrologic Model---PIHM Xuan Yu, Chris Duffy, Gopal Bhatt Anna Lamacova, PavelKram Civil & Environmental Engineering @ The Pennsylvania State University Czech Geological Survey Soiltrec Training Event Modelling Workshop - Crete

  2. Outline • Partition Calibration Strategy • Long term SSHCZO hydrological reanalysis • Spatial parameter transferability (Yong Womans Creek ) • SoilTrEC sites application—validated by snow depth(Lysina) Soiltrec Training Event Modelling Workshop - Crete

  3. Hydrological model calibration • Manual Calibration • set up model for simulation • Decide the range for each calibration parameter • Give a initial guess of each parameter • Compare model results to the observation • Give hydrologic explanations for the simulation error • Give another guess according to parameter sensitivities based on previous simulations • The calibration processes will cost the modeler’s long time working • When can we stop the calibration processes • Final results usually depends on the modeler’s experience Soiltrec Training Event Modelling Workshop - Crete
