This phenomena has caused floods in urban region in recent decades. Recently, MOEA and Ministry of Interior refer applications and regulations of urban development and governance worldwide, these applications is the foundation of new governance applications which will operated in Taiwan in future. Main idea of the improvement is based on LID (Low impact developement) and related techniques which has operated in the U.S. for more than decades. The objectives of the application are reducing risk of urban floods, instantaneous flow of drainage system and magnitude of sewage system construction in the future. However, massive and high density development of the urban region always facing high risk of flood during extreme precipitation. Assessments of LID application and related techniques is the main idea of this study. In specific, the assessment is focus on the comparison of drainage capacity between LID and traditional sewage system. This study will discuss a case study in Taipei area. Generally, this study will collect basic data of sewage system within the region and apply with SWMM (Storm Water Management Model) to manipulate the reaction of drainage capacity for different setting of precipitation. Moreover, this study will analyze the scenes of LID application in the same setting of manipulation. The results will be emphasized for the difference which had been made by LID applications. Outcome of the study will be benefits on the quantification assessment of drainage capacity of LID application, and the expert consultancy of planning to partitioning applications of LID and traditional construction to the suitable environment.低衝擊開發技術暴雨管理模式雨水下水道系統Low Impact DevelopmentStorm Water Management ModelSewage System
