近年來氣候變遷跡象日益顯著，極端水文事件頻仍，單一事件降雨強度與累積雨量均較以往來得劇烈，水患常伴隨著其他災害發生，複合型災害發生頻率與損失有加劇之趨勢，台灣地區未來將水患治理及防災工作勢必將接受更嚴苛的挑戰。本團隊期透過本計畫執行，以流域管理考量為出發點，強化更新分散於經濟部水利署、農委會水土保持局、農委會林務局、中央地調所、公路總局及中央氣象局相關災害資訊，如水災災害、土砂災害、公路災害及地震災害等資訊
透過本團隊彙整各單位之資訊，並分析流域系統內各種歷史災害資訊之關連性，利用建置之資訊平台之展示以充分掌握颱風豪雨期間發生於流域系統內之各項災害位置及資訊，進一步提供水利署防災應變期間決策者相關決策參考，可加強水利署於防災應變期間對各種災害資訊之掌握，以因應氣候變遷對水利業務之衝擊；另藉由坡地崩塌機制探討，進一步研究崩塌預警警戒機制之可能。本計畫辦理工作項目規劃如下：
(一) 基本圖資及相關資訊更新及擴充
(二) 地理資訊展示平台功能強化、更新及擴充
(三) 建立並即時傳遞災害整合資訊予決策者
(四) 坡地崩塌機制探討與崩塌警戒雨量設定之檢討 Climate change causes more extreme weather events in the world, and we have got heavy rainfall and intensity in the record. More and more disaster usually accompanies flood. We should face the extreme rainfall and the more complex disaster in Taiwan in the future. We must face the flood management and the work will be a challenge. We will execute this project from watershed management, and collect the data of Central Geological Survey, Soil and Water Conservation Bureau Council of Agriculture, Water Resources Agency, Forestry Bureau, Directorate General of Highways, and Central Weather Bureau. These data are about flood, debris flow, landslide, earthquake, and road disaster.
We will establish the relationship between all historic watershed disasters. Using the integrated system, we can get real and correct information about typhoon and flood in the watershed disasters. The system information will be used and transmitted by WRA to policymaker during the typhoon and flood happen. Moreover, disaster mode caused by the landslide is studied in this project. The items about this project as follows.
1. System data collection, expansion and be renewed.
2. GIS system strengthen and expansion.
3. Real time information is transmitted to policymaker.
4. Study and review the model and the warning rain values about the landslide.
