### P1 — match diagram naming (labels only, no schema change) - "Inlet Elevation" → "Inlet (bottom of pipe, m)" - "Outlet Elevation" → "Outlet (top of pipe, m)" - "Overflow Level" → "Overflow (weir crest, m)" - "Basin Bottom (m Refheight)" → "Basin floor above datum (m)" - Added a one-line banner at the top of Basin Geometry: "All heights measured from the basin floor (0 m)." These map directly to the clarifications added to basin-model.drawio.svg so editor and diagram speak the same vocabulary. ### P3 — live derived safety levels next to the % fields Low/High Volume Threshold fields now show the resulting trip level live as the operator types: Low Volume Threshold (%) [ 2 ] → dryRunLevel ≈ 0.21 m High Volume Threshold (%) [ 98 ] → overfillLevel ≈ 4.41 m Recomputed on every input/change of outflowLevel, inflowLevel, overflowLevel, minHeightBasedOn, or either %. Pure UI feedback — no schema change, no save-side change, same formulas as specificClass._validateThresholdOrdering(). Also includes the user's latest basin-model.drawio.svg update (inlet=bottom/outlet=top labels + datum annotation). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Diagrams
Editable source diagrams for the pumpingStation wiki. Each diagram is a .drawio + .drawio.svg pair, so anyone can edit the source in draw.io without touching any Markdown.
Why two files?
| File | Role |
|---|---|
<name>.drawio |
Native draw.io XML. The canonical source. |
<name>.drawio.svg |
SVG export of the same diagram (with source embedded). What the wiki actually renders, and what round-trips back into draw.io. |
Checking both in means the wiki renders for everyone, and the next editor picks up from exactly where the last one left off.
Editing workflow
- Clone the repo (you likely already have it if you're editing):
git clone https://gitea.wbd-rd.nl/RnD/pumpingStation.git cd pumpingStation/wiki/diagrams - Open the
.drawiofile in draw.io:- Web: app.diagrams.net → Open Existing Diagram, or drag-and-drop.
- Desktop: drawio-desktop.
- Edit — move shapes, change labels, adjust layout.
- Export to SVG with the source embedded:
File → Export as → SVG…- Check Include a copy of my diagram ← this is what lets future edits round-trip through the SVG.
- Save next to the source as
<name>.drawio.svg(overwrite).
- Commit & push both files:
git add wiki/diagrams/<name>.drawio wiki/diagrams/<name>.drawio.svg git commit -m "Update <name>: <what changed>" git push
Referencing a diagram from a wiki page
In any Markdown page under wiki/:

Use a descriptive alt text; it's the fallback if the SVG fails and it shows up in exports.
Naming
- kebab-case, one concept per diagram.
- Current diagrams:
| Diagram | Shows |
|---|---|
basin-model |
Physical basin cross-section — walls, pipes at their real heights, control thresholds cutting across, zone labels |
control-zones |
Vertical level axis ("thermometer") for levelbased mode — STOP / DEAD ZONE / RUN with demand ramp |
safety-rules |
Dry-run vs overfill rule asymmetry — which children stop, which keep running |
Making a brand-new diagram
- Open draw.io, start blank.
- Draw it.
File → Save As…→wiki/diagrams/<name>.drawio.File → Export as → SVG…with Include a copy of my diagram checked → save aswiki/diagrams/<name>.drawio.svg.- Reference from the wiki page with
. - Add an entry to the table above.
- Commit all three files together (
.drawio,.drawio.svg, updated.md).
These starters are rough
The .drawio files and their matching .drawio.svg exports committed here are placeholders — layout is approximate, colors and fonts are defaults, no fine alignment. They're meant to be a starting point; open them in draw.io and refine.
Both formats are round-trippable: open either the .drawio or the .drawio.svg in draw.io and it will load the editable model. (The SVG has the drawio XML embedded in a content="…" attribute on the root <svg> element — that's what lets draw.io re-open its own SVG exports.)
