摘要:	本文主要動機為探討都市開發及規劃時，就土地使用分區管制強度調整、增加入滲設施及滯洪空間或設施等環境管制方式，對排水設施入流量與逕流量減少之影響，進而達到改善都市淹水之情形。本文旨探討都市開發與雨水下水道系統規劃之配合，利用地理資訊系統（GIS）之建置數據資料，再應用暴雨經理模式（SWMM）進行都市排水設施系統之模擬分析方法，分析各項環境管制項目對集水區之保水、降雨逕流與洪氾之影響，並以臺北市木柵地區為研究範疇，如何藉由各項環境管制強度並配合運用低衝擊開發（LID）的概念改善排水設施系統規劃設計，以降低排水設施入流量與逕流量減少，並具體提出改善策略，做為都市規劃者之實際應用參考。其研究目的分為二：一為探討現行都市環境規劃對都市淹水之影響，二為透過實例模擬分析進而提出改善都市淹水之都市環境管制策略。本文係依據「臺北市雨水下水道設施規劃設計規範」採用之合理化公式所求出五年一次頻率之降雨強度，其降雨延時分別以每5分鐘為一時序至120分鐘時之尖峰流量，進而推得下水道系統中各入口人孔入流歷線，另以文山區雨水下水道管線及人孔資料作為SWMM模式分析的基礎資料；透過分析各集水區下水道管線、人孔資料之尖峰流量，進而判斷研究範圍內易淹水地區及其原因，並配合都市計畫法之土地使用管制規則、都市設計準則、建管規定等層面分析其都市環境管制規劃上之缺失。經暴雨經理模式分析現況得知，除須增設下水道抽水站外，針對本文範圍之改善策略建議將研究範圍分為上、中、下游三個區塊，其上游山坡地地區設置雨水截流管，將截流之雨水排入研究範圍外新店區西南側的碧潭一帶，用以減少自上游沖刷下來的雨水流量；另中游地區部分則考量當下游排水系統之容量不足以應付上游時，則增設蓄洪池，將其雨水貯留於中游，以減少下游下水道之水量；最後下游部分，將研究範圍內雨水下水道重新規劃並設置完備，另對其地區土地使用管制上加強管制基地保水原則，設置雨水花園等以減少都市不透水面積，設法增加地表滲透率。最後，因本研究僅針對木柵地區雨水下水道進行模擬分析，其模擬條件未考量水質部分，故建議後續研究可加入水質部分進行模擬。 This main motivation is when exploring urban development and planning, the impacts of adjusting the control intensity of land use zoning, increasing infiltration facilities and detention space or facilities and other environmental control methods on reducing inflow and runoff for drainage, and then achieves the improvement of urban flooding. This paper aims to explore the coordination of urban development and storm sewer system planning by making use of the database of Geographic Information System (GIS) and then applying the Storm Water Management Model (SWMM) to proceed the simulation analysis method of urban drainage facilities system and to analysis the impacts of every environmental control projects on the water retention in the catchment area, rainfall runoff and flooding and this study focuses on Taipei Mucha area to see how to improve the planning and design of drainage facilities system by the intensity of every environmental control with making use of the Low Impact Development (LID) concept to reduce the inflow and runoff of drainage and then specify the improved strategy as a practical application reference to urban planners. The study purpose is divided into TWO: One is to explore the impacts of existing urban environmental planning on urban flooding and another one is to bring up the urban environmental control strategy of improving urban flooding through the actual example simulation analysis. This study bases on the rationalization formula “Taipei City storm sewer facilities planning and design specifications” used to obtain the rainfall intensity of the frequency of once in five years. The rainfall duration is indicated by peak flow of one timing which is calculated by every 5 minutes to 120 minutes and then to infer every inlet manhole inflow hydrograph in sewer system and also use the storm sewer pipelines and manhole information in Wenshan District to be the basic data for SWMM analysis. By analyzing sewer pipelines in every catchment area and the peak flow of manhole information to determine where the areas are easy to have flooding and the reasons within this study scope and then coordinate the Urban Planning Law of the land use control regulation, urban design guidelines, construction management and other aspects to analysis the defects of urban environment control planning. After the Storm Water Management Model analysis for current situation, in addition to establish the sewer pumping stations, for the improved strategy in this study scope, it is suggested to be divided into three blocks, which are upstream, middle stream and downstream. To set up the storm interception pipe on the upstream hillside and then discharge the storm into the Bitan, southwest side of Xindian District, which is outside this study scope to decrease the washout of storm flow from the upstream to downstream; The consideration for the middle stream is when the downstream of drainage system capacity is insufficient to handle the upstream, the flood storage tank will be built to keep the storm in the middle stream to reduce the amount of water in the sewer at downstream; Finally for the downstream, the storm sewer within this study scope will be re-planned and settled up completely and also will strengthen the water retention principle of control bases for the land use control and establish rain garden ect. to reduce urban impervious area and try to increase the surface penetration. Finally, because this study only aims to Taipei Mucha area to do the simulation analysis for its storm sewer and does not consider the water quality in the simulation condition, therefore the future study is suggested to add the “water quality” to carry out the simulation.
