Models and Data over time Data Models

Models and Data over time 1996 -2001 DSM 2 Re-Calibration Late 80’s early 90’s Link-Node and Since 2000: DSM 1 DSM 2 Model • Expanded USGS Flow Network Models Appears • Bathymetry data collection by DWR CD • Expanded understanding of Delta transport Since 2000: • Stakeholder participation • Expanded USGS Flow Network (23 stations) • Bathymetry data collection by DWR CD • Expanded understanding of Delta transport • Stakeholder participation Mid 90’s USGS Flow Network NOAA Where we are today bathymetry data Data Models

Motivation for 1996 -2001 DSM 2 Calibration PWT

Motivation for 1996 -2001 DSM 2 Calibration PWT • Managers were frustrated with modelers

Motivation for 1996 -2001 DSM 2 Calibration PWT • Managers were frustrated with modelers FDM Old River Net Flow Old River/Middle River Flow Split ~ 50/50 DSM 1 Middle River Net Flow

Motivation for 1996 -2001 DSM 2 Calibration PWT • Managers were frustrated with modelers • Availability of new Delta flow data Permanent Flow Monitoring Network USGS “Confluence Study 1998” Montezuma Slough Chan 511 @ length Sacramento River Chan 435 @ middle Sherman Lake @ Sac R Chan 281@ San Joaquin R @ mouth Chan 286@ 0. 75*length o.

Motivation for 1996 -2001 DSM 2 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

Motivation for 1996 -2001 DSM 2 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 DSM 2 is accurate enough for the questions we ask of it.
