From one map to 377 grids: How technology helps read the Yangtze River
Date: 2026-03-23
From one map to 377 grids — this is how forecasting along the Yangtze River has evolved.
Today, rainfall is tracked at a 5 km × 5 km resolution, with flood signals able to be identified up to 10 days in advance.
Behind these numbers is a shift from experience-based judgment to data-driven systems, helping to anticipate floods earlier and keep the river in balance.
