  1. Land Sediment Calibration Jing Wu Modeling Subcommittee 04/03/2007

  2. Wash off Generation Attachment Rainfall Detachment Land Sediment Simulation Detached Sediment KSER KRER AFFIX NVSI Soil Matrix (unlimited) 4 parameters, 1 target

  3. Decision Rules for Key land Parameters • Zero Detached Sediment after large storms • Detached Sediment storage reaches 90% of its Max in 30 days • Generation makes up significant portion of Detached Sediment

  4. Strategy: Reduce the Parameter Set • AFFIX = 0.0765 • Assume NVSI : EOF target = 1.5 • Assume KSER : KRER = 5 • Adjust KSER to meet target

  5. What’s New? • New hydrology calibration • New land cover • Simulation extended to 2005

  6. Calibration Results

  7. Calibration Results
