Flood potential in Zhongzheng District, Keelung City

Zhongzheng District covers 14.0 km². Under 24 h / 350 mm, 0.1 km² (0.6%) is simulated to flood above 0.3 m; under 24 h / 650 mm, 0.2 km² (1.3%). The table gives all ten scenarios and five depth classes.

The simulated flooded area here is tiny (under 0.5 km²); the share is not meaningful — look at the map instead.

Areas are sums of 40 × 40 m cells. Nationally the cell sums run 0.3–0.5% above the original polygon areas (measured per scenario); the error is larger for small townships. A scenario is a design rainfall: total over the duration, not per hour. The depth class is the maximum simulated depth in the cell.
