林邊溪滯洪減災之研究

The Study of Flood Disaster Reduction by Detention Pond in Linbian River

指導教授 : 鄒 禕 陳金諾

摘要


本研究以地文性淹水模式模擬林邊溪流域下游地區,根據不同重現期2年、5年、10年、25年、50年、100年以及200年之一日暴雨量進行淹水模擬。探討林邊溪集水區內在滯洪池設置前後之淹水潛勢、淹水體積與淹水災害損失評估。藉由淹水模擬所演算不同重現期距之設計暴雨下所得到之淹水深度,搭配養殖漁業平均淹水深度─損失經驗曲線,求得不同頻率年雨量下研究區域內每單位面積災害損失。本研究設置三組滯洪池方案分別為羌園排水下游、羌園及塭仔排水上游同時設置和羌園及塭仔排水中游同時設置進行討論,結果顯示,於Case3羌園排水下游與塭仔一號排水中游同時設置滯洪池時其減少淹水體積、漁塭淹水體積與漁塭淹水損失中效益最佳。對滯洪池之設置而言,除了考慮減少較大之淹水體積外,也應同時考慮區域內之各種經濟產值,以減少較多淹水災害損失金額。

This study used Physiographic Drainage-Inundation model to simulate the inundation editions for 2 year, 5 year, 10 year, 25 year, 50 year,100 year, and 200 year return periods, for the downstream area at Linbian River Basin. The inundation potential, inundation volume and disaster loss evaluation of the research area are studied. Based on the results of the simulation and the curve of inundation Depth- Loss that the unit inundation loss under different return periods were estimated. In this study, three cases are analyzed, the first case detention pond located at downstream of Qiang-Yuan Drainage, the second case detention pond located at upstream of Qiang-Yuan Drainage and upstream of Wen-Tzu Drainage, and the last case detention pond located at dowstream of Qiang-Yuan Drainage and middlestream of Wen-Tzu Drainage. The final results showed the reduction rate of the monetary loss caused by storm events for different return periods are found to be most significant in case 3. This indicates that in addition to considering reduction in the flooded volume, the detention pond should be installed at the area with higher economic production values so that the monetary loss due to inundation can be diminished.
