  1. Coupled Model ExerciseExercise 3 George H. Leavesley, Research Hydrologist, USGS, Denver, CO

  2. TOOL BOX MODELING VIEWS • Research Model Developer Complex Detail • Application Model Developer • Model User • Resource Manager • Policy Maker Condensed Analysis

  3. LEVELS OF MODULAR DESIGN • PROCESS • MODEL • FULLY COUPLED MODELS • LOOSELY COUPLED MODELS • RESOURCE MANAGEMENT DECISION SUPPORT SYSTEMS • ANALYSIS AND SUPPORT TOOLS Single Purpose Multi-objective, Complex

  4. CRITERIA AND RULES FOR GOOD MODULE DESIGN • relate directly to real world components or processes • have input and output variables that are measurable values • communicate solely via these input and output variables Modules should Reynolds J.F., and Acock, B., 1997, Modularity and genericness in plant and ecosystem models: Ecological Modeling 94, p 7-16

  5. Model Building Tool - XMBUILD

  6. Watershed Model Hydraulics Model Fish Model LOOSELEY COUPLED MODELS MMS Model Off-the-shelf Model Database Data Management Interface (DMI)

  7. Watershed Model Fish Model LOOSELEY COUPLED MODELS PRMS Channel Geometry Analysis Program (CGAP) Hydraulics Model Habitat Suitability Index

  8. OBJECT USER INTEFACE (OUI)

  9. Other Model Integration Approaches • U.S. • BASINS (EPA) • FRAMES (DOE, NRC, DOD, EPA) • DIAS (DOE) • XMS (WMS, GMS, SMS, … - EMS Inc.) • OMS (USDA) • International • HarmonIT (Europe) • Catchment Modeling Toolkit (Australia)

  10. Exercise 3 Problems • 1.0 MMS_PET • Process comparison • 2.0 MMS PRMS Daily Mode • Watershed model evaluation • 3.0 MMS PRMS-HIS • Coupled watershed-hydraulics-habitat model

  11. - Hamon potet(HRU) = hamon_coef(mo) * dyl2 * vdsat - Jensen - Haise potet(HRU) = jh_coef(mo) * --------------------------- -- (tavf(HRU) - jh_coef_hru) * rin Potential Evapotranspiration (potet)

  12. PRMS

  13. HRUs

  14. Watershed Model Fish Model LOOSELEY COUPLED MODELS PRMS Channel Geometry Analysis Program (CGAP) Hydraulics Model Habitat Suitability Index

  15. Channel Cross-section

  16. Channel Characteristics

  17. Basic Channel Hydraulics Q = A*V V = 1.486/n * R2/3 * S1/2 n is Mannings n R is hydraulic radius S is channel slope

  18. Habitat Suitability Index – Velocity

  19. Habitat Suitability Index - Depth

  20. Weighted Usable Area (WSU) WUA = S ( velocity_hsi * depth_hsi * x-sect_width * 100.)
