降雨回收利用及補注效益之評估
Evaluation on the Groundwater Recharge's effect from Rainfall recycling
摘要
雨水收集利用能源少且無污染、又易於取得、無水權爭議、水質亦佳，是一種經濟又實用的水源開發模式。本研究提出以綠建築收集降雨貯存，及做為利用，進而可配合建築深層開挖時所遺下之點井，有效引雨水入滲至地下以改善地表不透水化所造成之不良影響。研究符合綠建築所強調之「防災減災」、「保水性」與「水資源利用及節水」等三項內容。根據本研究提出之系統概念，配合研究成果所得之系統各部設計建議，可據以做為後續進行實體建築應用時之參考。 本篇以桃園地區做為研究的區域，利用電腦算出模擬區一定時期之降雨－逕流情形，並根據時降雨量的多寡設計出適用於該模擬區域之雨水貯留槽容量，其中並利用FEMWATER數值模式模擬不同井深之地下水補注情形，以評估雨水回收利用及補注之效益，找出適用於此地區的雨水利用方案。

Collecting rainwater to utilize is an economical and useful model to develop source without consuming energy, without pollution and can be obtained easily. The study focuses on collecting rainwater to store up by Green Architecture and could use rainwater during aridity. Then ,the building uses both the remained well points from deep digging and the Architecture Rainwater Harvesting System to efficiently guide the rainwater to infiltrate to underground so that the negative influence caused by consolidating soil will be eliminated. This study matches the ideas of “Disaster Prevention and Reduction,” Wateriness and “Water Resources Utilization and Water Saving” in the Green Architecture concept. The excogitation suggestion from the system’s abstraction can be referenced by existing build’s application with advanced study and cooperation of different department. The study data is collected from Taoyuan computation is used to calculate the mount of rainfall the rain-off condition .The storage to be suitable for the selected area can be designed by the mount of rainfall collect. According to the mount of rainfall designs the storage to be suitable for the area. Then use the FEMWATER’s computation to simulate the condition of rechargeable groundwater. It could estimate the benefit that rainfall retrieves, and to find out the applicative alternative plan.
