Scenario — what-if regulation
Set the pond, the release to be passed downstream, and the four canal indents — the engine recomputes the SOP gate plan live.
Lift gates yourself: click a bay in the gate plan, set its opening — discharge follows the gate equation, the pond rises or falls by mass balance (indicative 25 km² pond), tailwater from the rating. Time runs at 1 s ≈ 15 min.
