Week of 2024/06/10: Project Briefing / Status Meeting

[rburghol]

Tasks:

Monday-Wednesday checkins include project overview meetings with analysts

• Review the SOW/contract.
  • Proposal_PBQETOQG_Scott (2).pdf
  • Precip Fidelity Project Overview model_meteorology#32
• Review initial data sources briefly.
• Go over some of the underlying questions.
  • https://github.com/HARPgroup/vahydro/issues/666
• Introduce sample data sets and gages #1270
• Review Connor's baseflow separation methodologies
• Discuss results of precip fidelity intro.

Administration

Morning: the 3 leads get together and review where we are in terms of:

• Background data sources
• Workflow software: Extending Meta-model meta_model#50
• Spatial SQL analysis tests and ideas Raster Data Inventory and Analysis model_meteorology#50
• Review test cases that we have assembled thus far (they are few, but interesting)
  • Have PRISM, NLDAS2 and daymet for 2023 ready in DB
    • DB connection not yet working (it works, but our backup streaming database is not totally up to date yet)
    • We need to generate the timeseries values for NF Shenandoah River for each to give to analysts (15 minutes effort)
• Date/time handling challenges and lessons learned. ensure consistent date, handling and storage in database model_meteorology#35
• Brainstorm:
  • Conceptual foundation for precipitation fidelity analyses Conceptual foundation for precipitation fidelity analyses #1279
  • First investigation:
    • Strasburg USGS gage
    • Obtain PRISM, NLDAS2, daymet data sources for 2023
    • Pair with USGS gage result to examine relationship between P and Q for 2023
    • Apply JPs model with these datasets?
    • Ideal case studies (initially) are ones with non-altered watersheds (headwaters, minimal impoundments/wd/ps)
    • Further cases studies consider
    • Choose times/places with known model errors.
      • NF Shenandoah at Strasburg (2023)
      • Rapidan River (2002?)
• What is our project scaffolding? The big picture?
  • Precip errors lead to model flow errors
    • Recharge precip (winter) determines summer base flow
    • Summer storms determine summer mean flows
  • This is a work-flow project that combines small, manageable steps
  • Tangible, small-wins, in the form of intermediate deliverables for analysts to anchor their work.
