The first was 2004, the "status quo" year. Next were the years 2013, 2019, and 2032. Flooding under three situations-doing nothing, using traditional methods, and using the new "living with nature" plan-were shown (see Figure 1) assuming current rates of subsidence and climate change.
游進裕解釋，第一個時間點以 2004 年規劃時做「現況年」，其次分別為 2013、2019、2032 年，以目前地層下陷速率和氣候變遷因素下，在 3 種情境──什麼都不做、用傳統工程手段、用「與自然共生」新方案──下，各會有怎樣的淹水情況（參見附圖）。
