DSM 2 Performance Measures Tara Smith CWEMF Annual

DSM 2 Performance Measures Tara Smith CWEMF Annual Meeting February 26, 2007 Delta Modeling Section Bay Delta Office

Presentation Overview • DSM 2 Calibration Evaluation Process • Background on DSM 2 Applications • Examples of Performance Measures Presented at Delta Modeling Workshop • Solicit Comments and Additional Ideas for Performance Measures • Start to Prioritized Performance Measures

DSM 2 Calibration Evaluation Process • First Step – Evaluate the performance of the current calibration of DSM 2 – Determine current and potential applications of DSM 2 – From those applications, determine and prioritize methods/measures to evaluate performance – Evaluate performance

Applications of DSM 2 • Application types – Historical – Forecasting (real-time and longer term) – Planning • Simulation types – Hydrodynamics (flow and water levels) – Conservative constituents (salinity) – Non-conservative constituents (Temperature, DO, TOC, etc) – Particle tracking

Current and Potential Applications of DSM 2 • Real-time applications – Operations – Emergency Response • Planning applications – Sea level rise – Island flooding – Frank’s Tract / 3 -Mile Slough – Storage and conveyance alternatives – South Delta and other barriers/gates – Changes in operations

Inputs for DSM 2 The February Delta Modeling Workshop touched on several issues related to the availability of DSM 2 input data, how it is used by the model and how it affects DSM 2’s results. – – – Geometry Flow Stage River and Ocean Boundary Water Quality Agricultural Consumptive Use and Quality http: //www. cwemf. org/Calendar/index. htm

Performance Measures (From Delta Modeling Workshop) • Amplitude and Phase Differences (Nader) • Tidally Averaged Data (Nader) • Harmonic Analysis (L. Smith) • Weighting Schemes Between Field Data and Model Output (Guerin) • Other Statistical Measures

Performance Measures (From Delta Modeling Workshop) • Match Tidal Prism (Enright) • Surface and Bottom Salinity • Impact of Location of Boundary Conditions on results (Enright, Shum, Nader) • Open Water Areas – Franks Tract (Shum) • Gate Operation (Shum) • Wind Effects (P. Smith) • Ocean Boundary Modeling (P. Smith)
