  1. Efforts toward CHPS Implementation at NERFC

  2. When we last met… • Issues on the table for NERFC included: • Commence migration activities • Transition to GFE QPF production • Test & Evaluate Daily QC as a means for MAP • Transition to GFFG • Work with Deltares on HEC-RAS • LOT to develop a Parallel Ops plan

  3. Progress report • Migration is nearly complete • A few lingering issues migrating the Hudson • Latest batch of RTI segments to be tested and implemented by Sept ‘09 • NERFC issuing all QPFs via GFE • Staff trained, worked out the kinks with the Verification folks and took care of in-house scripts for web graphics

  4. Progress report • Daily QC grids being run daily • HAS unit leading this effort • Comparison data sets available back to April 2009 • Staff to be trained Aug/Sept • GFFG up/running in parallel • 2 x a day – posted to a web page • WFOs evaluating in real-time

  5. Progress report • Continuing to work closely with Deltares on HEC-RAS • Connecticut river running on laptop • Includes a dam with gates and a levee • Successfully runs over 3 month period including spillway activation and levee breach • Still awaiting CHPS/LINUX version

  6. Progress report • Local Implementation Plan for Parallel Operations has been developed • Under final review at this time • Items addressed include: • Forcings and Forecast comparisons/validation • Forecaster assignments • Workload assessment

  7. Challenges in Migration Process • Migration has been time consuming • Frustration over failure of migration scripts following various upgrades and installations • Embedded nature of variables being referenced in many different locations has made trouble shooting very difficult and solutions are not always intuitive • Migration training was too short – needed to include in depth discussion of system, file structure and trouble shooting • What was provided was excellent • Note that NERFC was brought into process late but we may actually be a good litmus test for the remaining 9 RFCs • On-line system still not functioning as expected • Hopeful that Sys Admin training will address its configuration, functionality, differences with Off-line system

  8. Challenges in Migration Process • Migration has been very rewarding • Great deal of satisfaction when you get a basin to work! • Each phone call to Peter or Matthijsduring the various “challenges” is a learning experience in itself! • Deltares support has been very good • Best results have come from combination of email/list server and one-on-one visits and phone calls • Two-day visits following the Testing workshops have been packed, very rushed – really need more than 2 days at this point
