Community Hydrologic Prediction System (CHPS) The Community Hydrologic Prediction System (CHPS) will enable NOAA’s water research, development enterprise and operational service delivery infrastructure to be integrated and leveraged with other federal water agency activities, academia, and the private sector.

12 So Why the Move to CHPS? To meet the growing demands of our customers Floods, Drought, Water Supply, HABs, Power Generation, Fisheries Management, Ecosystem Health, Water Quality, Salt Water Intrusion, Dam/Levee Failures, Tropical Cyclone Impacts, Climate Change Impacts

13 Why CHPS? NWSRFS was a great architecture originally developed for use on mainframe computers –lacks modern modularity –difficult to add new models and techniques –inhibits collaboration and research to operations CHPS will allow: –greater ease in implementing new models –greater collaboration with agency partners, universities, international community s 1980s 1990s 2000s 2003 today 1970s 1980s 1990s 2000s 2003 today

14 The CHPS Acceleration Team – or CAT pursuit of CHPS –ABRFC, NCRFC, NWRFC volunteered to work w/ OHD. CNRFC later drafted. –Criteria established through evaluation of NWSRFS strengths and weaknesses (Apex facilitation, available from HSEB) –Evaluate Delft-FEWS as a CHPS candidate –FEWS = Flood Early Warning System The CHPS Acceleration Team – or CAT pursuit of CHPS –ABRFC, NCRFC, NWRFC volunteered to work w/ OHD. CNRFC later drafted. –Criteria established through evaluation of NWSRFS strengths and weaknesses (Apex facilitation, available from HSEB) –Evaluate Delft-FEWS as a CHPS candidate –FEWS = Flood Early Warning System CAT River Forecast Centers Beta Sites (2003) Exploration phase in 2003

15 FEWS Architecture 15 (2003) What is FEWS? –JAVA based system and repository for hydrologic and hydraulic modeling –Client/server architecture –Mature system developed by Delft Hydraulics|WL (now Deltares), a Dutch foundation, since the 1990s –Deterministic and ensemble capabilities –Employs Postgres database, system synchronization Backup and stand-by –Inputs are grids!

Target operational use at all RFCs within 3 years.Target operational use at all RFCs within 3 years. Resource implicationsResource implications –Re-direct OHD resources toward CHPS/FEWS –Terminate “dead-end” NWSRFS enhancements –Align/re-evaluate HSMB-oriented “Research to Operations” (RTO) projects 17 Approved by Office Director – Gary Carter – Jan 17, 2008 (2003)

21 Implementation Strategy Two tiers of deployment 4 CAT RFCs: CN, NW, AB, NE –Initial hardware delivered Oct ‘08 (Stand-by System) –Initial migration software and training occurred in February ‘09 –Second suite of operational hardware delivery fall 2009 (On-line System) –Full Baseline Operating Capability BOC-1 arrived in October (2003) Parallel operations are about to commence at NERFC!!

22 Implementation Strategy Two tiers of deployment Remaining 9 RFCs (BOC-2) –Initial hardware delivery in October 2009 –Migration/Systems training – Fall 2009 –Migration begins January 2010 –Parallel operations by October 2010 –Goal is to “Retire” NWSRFS by January 2011 –Entire system needs to be baselined into AWIPS II configuration at the RFCs 22 RFCs not required to drop NWSRFS until “fully ready” (2003)

23 Ultimate Outcome: CHPS will include the same science algorithms initially – but tremendous potential to expand Improved Efficiency for Forecaster –Greatly enhanced visualization, gridded forcings, and the ability to display time series of many more variables Improved Tools for “What If” Scenarios Improved Capabilities for New Science Integration –Through the use of Adaptors; HEC-RAS, RESSIM –Availability to use models in FEWS from other partners CHPS will include the same science algorithms initially – but tremendous potential to expand Improved Efficiency for Forecaster –Greatly enhanced visualization, gridded forcings, and the ability to display time series of many more variables Improved Tools for “What If” Scenarios Improved Capabilities for New Science Integration –Through the use of Adaptors; HEC-RAS, RESSIM –Availability to use models in FEWS from other partners
