  50. Expected Timeline for Technical Team Review Technical Team Review 5/2/2016 - 7/1/2016 6/1/2016 - Planning Level Model Updates 7/29/2016 Model Files Preparation for 4/18/2016 - 5/2/2016 Review Technical Team Meeting 5/11/2016 Model Calibration Completed Initial Comments Final Comments 4/18/2016 5/27/2016 7/1/2016 Model Delivery Technical Team Meeting Technical Team Meeting 5/2/2016 6/1/2016 7/6/2016 2016 Apr May Jun Jul Today 50

  51. External Peer Review Process  Develop selection criteria  Develop a list of potential candidates  Tech Team provide suggestions for consideration by 5/18/2016  Develop a short list  6 for MODFLOW (3 primary, 3 substitute if needed)  3 for HSPF (1 primary, 2 substitute if needed)  Select top 3 candidates for MODFLOW model and 1 candidate for HSPF models  Contact the candidates for availability 51

  52. Selection Criteria General Criteria  Free of conflicts of interest  Not member of the model development team  Not member of the technical review team  Well qualified by virtue of education and work experience  Responsive and able to meet deadlines Specific Criteria  Experience in constructing and calibrating a regional-scale groundwater flow model  Educational background in engineering, geology, hydrology, or other related earth science Specialized expertise or experience in one or more of the following is beneficial  Development of models with an emphasis on surface-water/groundwater interactions  Developing groundwater flow models for Floridan Aquifer system  Analysis or modeling of near-surface hydrological processes  Experience in calibrating regional groundwater models using PEST  Experience in peer review of regional groundwater flow models using MODFLOW code 52

  53. Next Steps  Technical Team Review  Model Scenarios  External Peer Review 53

  54. Upcoming Meetings  Technical Team Meetings  June 01, 2016  July 06, 2016 (could be a joint meeting w/ Steering team) 54
