Summary:	台灣因地理位置的因素而經常遭遇天然災害，其中每逢颱風、豪雨便容易有水患災情；再加上近年來全球天氣異常、氣候極端，導致短延時強降雨型態之極端氣候發生頻繁。這樣的氣候變化及降雨型態對於山高水短的台灣地形來說，是最不利的降雨型態，加上都市化過程中，大量使用不透水鋪面使得高不透水率。在降雨過後造成地表逕流量與洪峰流量的增加，造成都市淹水現象的發生。考量目前人力、物力與空間欲單藉強化既有排水系統，因應前述氣候與環境因素造成之衝擊，實有其難處。故現今國際間防洪思維改變，藉兼顧基地保水、滲透雨水、涵養地下水之透水城市概念。從源頭直接降低逕流洪峰量並將部分的雨水保留以避開洪峰，來達到防洪減災的目的。本研究藉由常態化差異植生指標進行綠覆率判釋，來估算目標區域逕流係數；並使用合理化公式之三角單位歷線法，來計算建築基地所需要之保水量以及允許放流量。在本研究假設的條件下，分析其成效；結果是在284.9平方公里都市發展區面積中可約保留5,380,383立方公尺雨水逕流量。 Taiwan is an island with various natural hazards. It is likely to cause flooding during typhoons or heavy rain. In recent years, global climate change resulted in frequent occurrence of heavy rainfall within a short duration. Such patterns are unfavorable to Taiwan because of the topography with high mountain and short river. In addition, the use of impermeable pavement in urban areas caused highly impermeable rate. Heavy rainfall could result in the increase of runoff and peak flow, inducing urban flooding. With the available resources, it is difficult to deal with the climatic and environmental impacts just by improving the existing drainage system. Therefore, the new methodology of international flood prevention has been formed, in which the concepts of water retention, infiltration of rainwater, and groundwater conservation are involved to reduce the amount of runoff directly and to store a part of rainfall to avoid the peak to reach the goal of flooding control. This study applied “Normalized Difference Vegetation Index” to identify the ratio of green-covered to estimate the target area runoff coefficient, and used rational formula of triangular unit hydrograph method to calculate the amount of water storage for the building site and the allowable discharge capacity. Under the assumption of this study, the benefit of rainwater conservation was evaluated. The result showed that approximately 5,380,383 m3 of rainwater runoff can be retained within the 284.9-km2 urban developing areas in Kaohsiung City.
