Efforts toward CHPS Implementation at NERFC

When we last met…Issues on the table for NERFC included:

Commence migration activitiesTransition to GFE QPF productionTest & Evaluate Daily QC as a means for MAPTransition to GFFGWork with Deltares on HEC-RASLOT to develop a Parallel Ops plan

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 GFEStaff trained, worked out the

kinks with the Verification folks and took care of in-house scripts for web graphics

Progress report Daily QC grids being run

available back to April 2009Staff to be trained Aug/Sept

GFFG up/running in parallel2 x a day – posted to a web

Progress report Continuing to work closely

a leveeSuccessfully runs over 3

month period including spillway activation and levee breach

Still awaiting CHPS/LINUX version

Progress report Local Implementation Plan

for Parallel Operations has been developedUnder final review at this

timeItems addressed include:

Forcings and Forecast comparisons/validation

Forecaster assignments Workload assessment

Challenges in Migration ProcessMigration 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 RFCsOn-line system still not functioning as expected

Hopeful that Sys Admin training will address its configuration, functionality, differences with Off-line system

Challenges in Migration ProcessMigration has been very rewarding

Great deal of satisfaction when you get a basin to work!Each phone call to Peter or Matthijs during 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
