8. Data Publication

9. Approval levels ‘Unprocessed’ data is what you see in the gauge house – by the time data gets into AQUARIUS it should already be ‘Preliminary’ ‘Preliminary’ data needs to be examined : a) To ensure that auto-processes are working correctly b) To correct deficiencies that auto-processes cannot handle The manual corrections applied to the data need to undergo scrutiny to ensure that they are complete, appropriate, and correctly applied Compliance with QMS objectives must be affirmed by a qualified individual before the data is ready for archive

10. Unprocessed to preliminary

11. Preliminary to Approved

12. Processes by activity

13. Primary Signal (e.g. HG Telemetry @ StationID) Working Signal ( e.g. HG Working @ StationID ) Contains both telemetry and logger if available, telemetry is, by design, the default RAW signal Derived Signal (e.g. QR Working @ StationID) Combines a time-series with a HydroML Discrete Signal (e.g. HG Field Visit @ StationID) HydroML (e.g. HG QR rating curve @ Station ID ) AQUARIUS data concepts

14. Every time-series is an AQUARIUS Optimized Package (AOP) which has these attributes: Raw Corrected Interpolation type Grades Flags Approvals Notes AQUARIUS data attributes

15. The raw signal is sacred - it cannot be edited or deleted The raw signal is the original input - regardless of where the input came from The RAW input to a ‘working’ signal is the CORRECTED primary signal Raw

16. The CORRECTED signal in an AOP is the RAW signal with all corrections applied to it The corrections are all date-stamped hence corrections can be turned on or off in any order Corrections are applied in sequence according to the date-stamp Corrected

17. Type 1 – Instantaneous value (e.g. HG) Type 2,3,4,5 – Value in preceding interval (e.g. mean, max, min or total for an aggregation interval) Type 6 - Instantaneous total(e.g. TBRG) Type 7 – discrete value – no interpolation Type 8 – Value in succeeding interval (e.g. Gate opening) Type 9 – Direction in preceding interval (e.g. Wind direction) Type 10 – Total in succeeding interval (e.g. Flow volume) Interpolation Type

18. Are agency specific and controlled with the admin tool as a definition table In WSC – BEAD - in that order. A is only relevant to daily aggregated values which, in HWS, is a reporting function. Grades

19. Threshold or Rate of Change detection based on: >, >=,. By design, flags on auto-processes apply to the CORRECTED signal Flags

20. Are agency specific and controlled with the admin tool as a definition table In HWS the approval states are: Unprocessed – data upstream of AQUARIUS Preliminary – have been auto-processed on append into an AOP Reviewed – have been scrutinized for validity and invalid data has been manually corrected or deleted Checked – the data have been peer reviewed Approved – the data have been assured according to national standards by a qualified expert Approvals

21. Notes are attached to an episode of data Comments are attached to any action taken on the data The default comment for any correction includes all details needed for reproducibility Free-form editing Advantage – you can be specific Disadvantage – sorting or searching by free-form may be unproductive Comment list can reduced typing Notes and Comments

22. AQUARIUS Propagation and Aggregation rules

23. Bench Mark Analysis – no Approval Field Visit Measurements – Approval but no Propagation Rating Curves – Approval and Propagation Rating Periods of Applicability – Approval and Propagation Shift Corrections – Approval and Propagation Approvals: mules and donkeys

24. Log tab in SB Log node in FVT Change history in DCT Corrections can be undone without affecting history Undone corrections can be deleted - then they are gone from history Log

25. Every action is attributed to the logged in user Change your password Actions can be sorted by creator User authentication

26. Pictures, scanned field notes etc. Original measurement files, logger files Attaching supporting documentation

27. Recalculate in FVT Default = do not calculate – current meter rating tables are not stored in HWS! Override of date in imported measurement – possible - but comment required Override of values, comments – not possible Other data modifications

28. The HWS is designed to support compliance with Standard Operating Procedures and Business Rules The SOPs and business rules will be in a state of flux for the next little while. Training  Trial Implementation  National Implementation
