1. National Hydrologic Model Calibration Lauren Hay US Geological Survey National Research Program (NRP) Modeling of Watershed Systems (MoWS) Denver, Colorado

2. THEN PRMS model applications with 1 stream gage

3. THEN PRMS model applications with 1 stream gage NOW PRMS applications with many stream gages HOW TO CALIBRATE??????

4. S. Platte River Basin THEN PRMS model applications with 1 stream gage NOW PRMS applications with many stream gages PRMS applications in ungaged basins Ungaged 25,000km2 Colorado The green shaded area indicates area that will be modeled hydrologically. The black and white circle indicates USGS streamflow gage 06754000, near Kersey, CO. The green circles mark the 14 seed dispersal phenology field sites. HOW TO CALIBRATE??????

5. Lumen Used to analyze a stream network represented within PRMS • 4 essential functions: • constructs the stream network graph • groups segments into rounds • draws a schematic • generates child parameter files

6. S. Platte River Basin Lumen reads parameter PRMS parameter file and generates schematic Ungaged

7. Using Lumen to Setup Parameter Regionalization Scheme Calibration gage (poi_type=1) Gage (poi_type=0) Stream segment break ROUNDS PRMS parameter poi_type Initial parameter file in lumen Parameter file for regionalization in lumen

8. Using Lumen to Setup Parameter Regionalization Scheme • Check Out: • Parameter File • CalibrationSession File • Climate Input Files Options for checking out child parameter files

9. Using Lumen to Setup Parameter Regionalization Scheme • Check Out: • Parameter File • CalibrationSession File • Climate Input Files Options for checking out child parameter files

10. Using Lumen to Setup Parameter Regionalization Scheme Check Out Round 1 Calibrate Check In Check in for parameter files

11. Luca • wizard-style user-friendly GUI • provides an easy systematic way of building and executing a multiple-objective, stepwise, automated calibration procedure for PRMS • uses the Shuffled Complex Evolution global search algorithm Hay, L.E., Leavesley, G.H., Clark, M.P.,  Markstrom, S.L.,  Viger, R.J.,  and Umemoto, M., 2006,  Step-Wise, Multiple Objective  Calibration Of A Hydrologic Model For A Snowmelt-Dominated Basin, Journal of American Water Resources.

12. Luca Session File

13. Using Lumen to Setup Parameter Regionalization Scheme • Round 2 Check Out: • Parameter File • Luca Session File • Climate Input Files Options for checking out child parameter files

14. Using Lumen to Setup Parameter Regionalization Scheme • Round 2 Check Out: • Parameter File • Luca Session File • Climate Input Files Calibrated in Round 1 Options for checking out child parameter files

15. Luca Session files generated by lumen Spatially distributedparameters Calibrated in Round 1

16. Lumen application: NHM in SE Lumen Rodney Knight (TN WSC) Ana Maria Garcia (NC WSC) Jacob LaFontaine (GA WSC) Jeffrey Riley (GA WSC) • WaterSMART Flow Model Comparison Project • Time series of estimated daily flows compared using statistically- and physically-based models. • 199 gages identified in the study domain as suitable for calibration/validation • Leave-one-out cross-validation

17. Summary • Regionalization approach using Luca and Lumen • Ana Maria Garcia – Alabama • Jacob LaFontiane – ACF • Eddie Haj – Upper Missouri • Ana Maria Garcia – Alabama • Ashley Can Beusekom – Puerto Rico • Steve Markstrom – S. Platte • Combine with Monthly Water Balance Model (MWBM) and with statistically based methods (SBM) • Bock – MWBM • Session in afternoon on SBM (Kiang, Over, Archfield, and Farmer)
