Community Hydrologic Prediction System

CHPS

NOAA’s National Weather Service (NWS) River Forecast Centers (RFCs) are key partners in the provision of water resource information.

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.


So why the move to chps to meet the growing demands of our customers l.jpg
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


Why chps l.jpg
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

1970s 1980s 1990s 2000s 2003 today

Beta Sites

  • 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

Exploration phase in 2003

  • CAT River Forecast Centers

(2003) 2006 2007 2008 2009 2010 2011

  • 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!

Cat recommendation l.jpg
CAT Recommendation 2009 2010 2011

Proceed with implementation of Delft-FEWS as the CHPS software infrastructure.

Target operational use at all RFCs within 3 years.

Resource implications

Re-direct OHD resources toward CHPS/FEWS

Terminate “dead-end” NWSRFS enhancements

Align/re-evaluate HSMB-oriented “Research to Operations” (RTO) projects

(2003) 2006 2007 2008 2009 2010 2011

Implementation strategy l.jpg
Implementation Strategy 2009 2010 2011

Port models that require calibration

Hydrologic/Hydraulic Models

Soil Moisture Models

Snow Models

Reservoir Models

BASEFLOW, SARROUTE, CONS_USE, LAG/K, LAY-COEF, TATUM,

TIDEREV, MUSKROUT, RES-J, RSNWELEV, SNOW-17, CHANLOSS,

STAGE-Q, SSARRESV, STAGEREV, UNIT-HG, RES-SNGL, SAC-SMA

Create adapters for other NWSRFS routines we wish to maintain

Create adapters for several new models (e.g. HEC-RAS)

Ensemble 2009 2010 2011Streamflow Prediction Services

  • FEWS will provide for existing level of ensemble operations, products, and services

    • Combination of porting existing software meshed with existing FEWS capabilities

Implementation strategy21 l.jpg
Implementation Strategy 2009 2010 2011

Two tiers of deployment4 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 2009.

(2003) 2006 2007 2008 2009 2010 2011

  • Parallel operations are about to commence at NERFC!!

21


Implementation strategy22 l.jpg
Implementation Strategy 2009 2010 2011

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

(2003) 2006 2007 2008 2009 2010 2011

RFCs not required to drop NWSRFS until “fully ready”

22


Ultimate outcome l.jpg
Ultimate Outcome: 2009 2010 2011

  • 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


Slide24 l.jpg

Architecture 2009 2010 2011

  • Duty (On-line) and Stand-by system

  • All data is synchronized between system via the Master Controller

  • NWS testing synchronization to paired offices – similar to WFOs
