1. Measures of Model Performance
Based on Last DSM2 Calibration Effort

2. Objectives
Stage
Flow
Water Quality (EC)

3. Stage
Instantaneous
Usually checked for a few short (A few weeks) but distinctly different flow periods
Check for Phase & Amplitude
Be aware of Datum issues!

6. Flow Instantaneous Check for amplitude, phase and magnitude
Large errors may imply lack of accuracy in geometry
(Usually checked for a few short distinct periods)
Tidal average
Can be checked for a longer period
Accuracy maybe an issue when net flows are small compared to tidal flows

7. Instantaneous Flow

8. Net Flows

9. Water Quality (EC) Primary focus on tidal day averages only
Dry periods provide the most interesting analysis (ocean salinity intrusion)
Errors in “net Delta outflow” estimates may lead to significant errors in EC estimates
