Dashboard walkthrough¶
The dashboard is a 3-column layout: left sidebar, center map, right detail panel.
Basin Overview (All mode): sub-watersheds colored by annual deficit, right panel showing basin-wide aggregates.
Left sidebar: filters and tabs¶
Four tabs:
| Tab | What it does |
|---|---|
| Basin Overview | WRUA dropdown, scenario picker, map layer toggles |
| WRUA Selection | Click any of the 119 WRUAs to drill in |
| Temporal Analysis | Filter the dashboard to a single month or year (2019 to 2023) |
| Export Data | CSV and PDF downloads for the selected WRUA |
Layer toggles control what the map shows:
| Layer | Description |
|---|---|
| WRUA Color Fill | WRUAs filled in their brand colors |
| Sub-Watersheds | Sub-watershed polygons colored by annual deficit |
| WRUA Boundaries | White outline around each WRUA |
| All WRUAs | The full set of 119 CHEF-region WRUAs (on by default) |
Center map¶
A Leaflet map centered on the Central Highlands Ecoregions Foodscape (CHEF), central Kenya.
- Hover any sub-watershed polygon to see its WS id, elevation, annual deficit, and surplus.
- Click a WRUA boundary (or a sub-watershed in "All" mode) to drill into that WRUA.
- Bottom-left legend shows the deficit colormap thresholds.
Right detail panel¶
In single-WRUA mode the panel shows:
- Header: WRUA name, total area, elevation range.
- Monthly Water Balance: 12-month bar chart of surplus (green, up) and gross deficit (orange, down), in Mm³, summed across all the WRUA's sub-watersheds.
- Deficit Intensity Matrix: heatmap of the top 10 sub-watersheds by peak monthly deficit. Rows are sorted by elevation (highest first), columns are months.
- Recommended Interventions: top 15 sub-watersheds by max monthly deficit, with pond counts and priority labels (high / medium / low).
- Export buttons: CSV (monthly rows) and PDF (10-page IWMI-branded report).
In "All" mode the panel shows basin-wide aggregates instead:
- Header with the WRUA and sub-watershed counts for the current selection
- Stat tiles: total area and basin elevation range
- Monthly balance chart summed across all WRUAs in view
- Top sub-watersheds basin-wide
- Top priority intervention sites basin-wide (labelled
WS {id} ({wrua}))
Tooltips¶
Hover any sidebar control, stat tile, or chart heading for a one-line tooltip explaining what it does. Useful when handing the tool to a new user.
