Storage-first scenario markers showing which projects could alter river timing, dry-season support, downstream sensitivity, and cooperation risk.
Summary
This layer is a scenario view of storage or storage-like projects that could affect river timing, dry-season support, downstream sensitivity, and cooperation context. It translates the storage shortlist into map fields for the geopolitics preset.
What It Represents
This layer reframes the Layer: Storage Shortlist for the geopolitics preset. The question is not only how many MW each project adds. The question is whether a project can change the timing of water and electricity enough to matter downstream.
The layer includes mapped storage or storage-like candidates from the existing shortlist:
| Scenario role | Meaning |
|---|---|
operating_baseline |
Existing storage that anchors the present system. |
near_term_storage |
Storage under construction or close enough to matter for near-term planning. |
advanced_planned_storage |
Planned storage with strong Nepal-side documentation and quantified dry-season value. |
promising_storage_candidate |
JICA/NEA promising-storage candidates with dry-energy or storage figures. |
How To Read It
Use this layer with Nepal-origin downstream systems, basin polygons, downstream impact markers, and origin/control callouts. A marker should answer five questions:
| Field | How To Use It |
|---|---|
Timing (scenario_horizon) |
Separates Already operating, Under construction, Planned, and Long-term candidate projects. |
Flow impact (regulation_potential) |
Indicates whether the project has baseline (no storage), low, medium, high, or very-high timing-regulation signal. |
downstream_name |
Names the downstream river system affected by the basin. |
Downstream risk (downstream_sensitivity) |
Flags whether the linked basin is geopolitically sensitive downstream. |
Cooperation needed (cooperation_potential) |
Identifies where regulation could create cooperative surplus rather than only unilateral leverage. |
The deterministic regulation classes are based on dry-season energy, total storage, and effective storage where available. They are scenario labels, not hydrodynamic model results.
Coverage / Method
The layer covers 11 scenario marker features derived from Layer: Storage Shortlist, storage_shortlist_annotations.geojson, and nepal_storage_dry_energy_shortlist.csv. Scenario fields classify timing, regulation potential, downstream river system, downstream sensitivity, and cooperation context from available storage, dry-energy, and status fields.
Caveats
This is a strategic interpretation layer. It does not model reservoir operations, treaty entitlements, flood-routing hydraulics, sediment trapping, irrigation withdrawals, or environmental-flow compliance.
Several projects are planning candidates rather than committed assets. Location precision varies by marker; use the Location source (location_basis) and confidence fields before treating a point as a site-grade location.
Storage Capacity Comparison includes Chera-1 in the tabular research workspace, but Chera-1 is not exposed here because it does not currently have a reliable map anchor.
