Basin 4 Working System Logic

This panel shows documented relationships already established in the project. Internal basin polygons and a complete hydraulic network will be added later.
Live System Map
The live map is integrated into System Dashboard so selecting a weir immediately updates the structure panel beside it.

Weekly Monitoring
Enter each dated canal/weir field round once. Every saved date becomes another point in the annual trend automatically.
Weekly Field Reading Entry
The analysis is date-based. Workbook labels such as “Reading 1” or “Reading 2” are treated only as source references, not as analytical cycles.
| Weir | Canal | Stage NGVD29 | State | Shutoff | Inches Available | Δ Prior | Notes |

Shared saving requires a WB Hub sign-in. Local drafts work immediately on this device.
Shared Access
SUPABASEChecking session…
The WB Hub uses the existing Stormwater Supabase backend. A future Brad/user account can use the same shared monitoring records without changing the weekly workflow.

This focus panel is intended to evolve into an operational Basin 4 summary combining weekly levels, gate settings, rainfall, and eventual SCADA history.
Annual Water-Level Trend
All dated weekly readings are combined into one calendar timeline and overlaid against prior years.
What the chart means
Each dot is one actual dated field reading. The Hub no longer compares “Reading 1 vs Reading 1.” Instead, it combines every reading chronologically so you can see how each weir behaves through the year and compare the shape of 2026 with 2025, 2024, 2023, and 2022.
Going forward: every weekly round saved in WB Hub automatically extends the 2026 line. Additional historical monthly workbooks can be added to fill Jan–Aug and Nov–Dec.

Annual trend — every available dated reading
Current historical files loaded in this build cover September and October. The chart is already structured for the full calendar year; months without loaded source data remain blank rather than being estimated.

Executive interpretation

“Inches above shutoff” remains the workbook-derived measure (NGVD stage − shutoff elevation) × 12. It is not volumetric storage. Higher/lower colors indicate direction only; they do not automatically mean good/bad operational conditions.
Operations Intelligence
Levels + documented control changes + hydraulic context for the selected structure.
Operational action markers
dashed markers on the annual chart = documented weir/system action
Hydraulic context
Estimated basin storage
Not calibrated yet.The legacy Canal Volume Trends workbook contains useful stage/storage concepts, but WB Hub will not convert stage to gallons until the applicable basin stage-volume relationship is validated for current conditions.
Rainfall & Telemetry Sources
What is connected now, what is ready, and what still needs City/provider access.
Rainfall Observation
MANUAL READYManual rainfall can be stored in the shared WB Hub after sign-in. NOAA ERR/SCaMPR is registered as a near-real-time source, but automatic ingestion is not enabled yet.
Trend Analysis
Historical manual readings + shared WB Hub readings.
Reading History
The original workbook remains a source record. WB Hub stores each reading as a time-stamped operational observation so it can be compared with structure actions and events later.
Weir Register
Master City weir list + live GIS attributes. The register remains usable even if the GIS service is temporarily unavailable.
| Weir | Canal | Location | Carp grate | Riser/control | Up basin | Down basin | Sill NGVD | Min crest | Max crest | Crest length |
|---|
Basins
The basin module is ready; authoritative polygons will be added when the internal layer is available. Upstream/downstream basin attributes from City GIS are already used at the structure level.
Events
Event reconstruction is a separate layer beneath daily operations.
