Abstract: 臺灣為防範颱風豪雨期間所帶來的危害,陸續完成各河川及排水出口之防洪整建,已有效減少市區洪水災害。而在雨水排水幹線建設部份,省住都局時期即依當時現況規劃雨水下水道系統,並據此規劃建設排水系統。然而,地方政府之雨水下水道管理,除對現況資料蒐集不全外,早期圖資受限於電腦技術發展,僅有圖紙資料留存,竣工資料保存不易,致使管理單位在遭遇颱風、豪雨、積淹水等天然災害時,常無法於第一時間掌握災區的下水道設施配置情形,也無法快速地擬定改善策略。在90年初期,臺灣逐漸引入GIS技術導入業務管理工作,期以資訊化方式將下水道紙圖、CAD檔案等圖資,納入GIS資料庫中,以利後續的查詢、管理等應用領域。本研究希望利用近來雨水設施普查之成果,轉製雨水下水道資料庫,建立相關機關或其他管線單位間資料的互通、應用與參考,使資料建置的成果能夠運用於水理分析軟體,以充份發揮資料整合與防減災應用效益。
In prevention of hazards during the typhoon and rainy seasons, the government has constructed a series of flood preventing systems and structures along various rivers and at drainage outlets. These constructions have greatly reduced the opportunity of flooding hazards in urban areas. Date back to era of the Taiwan Provincial Government, the Public Housing and Urban Development Bureau had made plans for the underground storm drains system and trunk lines according to the conditions of that time. These plans were then used as a reference to construct drainage systems after. For underground storm drains management, the local governments now is lack of comprehensive records of the current conditions. Only printed version of earlier maps and data are available, due to the limited computer technologies at that times. It was also difficult to preserve and maintain records of completed projects. As a result, the administration has difficulties to understand the whole drainage situation in affected areas during typhoons, heavy rain, flooding, and other natural disasters. Therefore, it is very difficult for them to promptly addressing these issues or proposing responding strategies. Since the early 1990s, the geographic information system has been introduced to the administration for spatial information management. The aim is to employ digital methods to import maps, data, CAD files, and other information of underground drains into the GIS database, thereby facilitating subsequent searches, management, and applications. The goal of this research is to make use of the recent rainwater facility survey and convert the survey data to establish a storm drains database. So the information can be easily shared among relevant public agencies and other pipeline management organizations. The proposed database can also be used in hydrologic analysis software to fully leverage the benefits of data integration.
