  1. Application of ANN Turbidity Model as A Gamming Tool March 16, 2015 Chuching Wang, Ph.D., P.E. Metropolitan Water District of Southern California

  2. Delta ANN Turbidity Model • Developed by Sujoy Roy of Tetra Tech and MWDSC. (2013/2014) • Paul Hutton • Chuching Wang • Calibrated using • Simulated long term model results • Observed historical data • Ease on input requirement

  3. Gamming Excercise • December 10, 2014, MWD Bay Delta Staff • Assumed Sacramento River hydrograph and turbidity. • Zero out San Joaquin River turbidity • Playing with various ranges of OMR index flow • Checked the turbidity performance at Prisoner’s Point.

  4. Scenario Notes • Input 1: 2012-13 historical • Input 2: Assumed 2014-15, no pumping cutback. • Input 3: Assumed 2014-15, -6000 cfs OMR index flow for 2-week. • Input 4: Assumed 2014-15, -3000 cfs OMR index flow for 2-week.

  5. Next Steps • Improve the ANN accuracy at certain key location. • Improve Gamming interphase. • Retrospective analysis of the 2014-15. • Further development on Delta Smelt movement prediction. • Future applications.
