  4. Models and Data over time 1996-2001 DSM2 Re-Calibration Mid 90’s USGS Flow Network NOAA bathymetry data Where we are today Late 80’s early 90’s Link-Node and DSM1 Models Data Models • Since 2000: • Expanded USGS Flow Network • Bathymetry data collection by DWR CD • Expanded understanding of Delta transport • Stakeholder participation DSM2 Model Appears • Since 2000: • Expanded USGS Flow Network (23 stations) • Bathymetry data collection by DWR CD • Expanded understanding of Delta transport • Stakeholder participation

  5. Motivation for 1996-2001 DSM2 Calibration PWT

  6. Motivation for 1996-2001 DSM2 Calibration PWT • Managers were frustrated with modelers

  9. Motivation for 1996-2001 DSM2 Calibration PWT • Managers were frustrated with modelers • Availability of new Delta flow data • Availability of new Delta bathymetry data Bathymetry data collected in 1999-2000

  10. Motivation for 1996-2001 DSM2 Calibration PWT • Managers were frustrated with modelers • Availability of new Delta flow data • Availability of new Delta bathymetry data • Recognition of the need for consensus among Bay-Delta modelers that DSM2 is accurate enough for the questions we ask of it.
