本研究擬建立一既有治理工程調整方法之評估機制,藉由利用土石流沖淤模擬並使用統計方法來進行各種方案之可行性評估,以改善仰賴經驗法則之工程調整評估方式。
進行評估時,先進行集水區內水文、水理演算,再推求各斷面間之最小通水高是否足夠,再利用土砂沖淤模擬之方法,以50 年設計降雨事件之尖峰流量進行長時間之模擬,得到之坡度即為平衡坡度,以此坡度進行既有工程構造物高度檢核,且以此為坡度調整之目標值,待檢核完成後訂定調整方案,而方案擬定後,仍需重新檢核其通水斷面積是否足夠,方案成能抵定,再以50年之設計降雨事件,模擬河床內土砂運移之過程,將模擬後之網格資料,即土砂沖淤量與原地形疊合得到沖淤地形變化值,最後再以統計方法-變異數分析進行河床內土砂沖淤之變化情形之趨勢分析,爾後方能討論出最佳方案。
This study was to establish a method of adjusting the existing treatment works assessment mechanism,by using simulation of debris flow deposition and Use statistical methods to assess the feasibility of various options, to improve the work rely on rules of thumb to adjust assessment.
Assessment, prior to catchment hydrology and hydraulic calculations, Again to seek the smallest among all sections of high water, the adequacy of communication, and use of sediment erosion and deposition simulation methods, use 50-years peak flow design rainfall events for long time simulation,to get equilibrium slope for constructions height check and adjustment of the target slope, check to be adjusted after the completion of the program set Simulate the process of river bed sediment transport by 50-years design rainfall event. To get grid data by simulation result,sum of variation of sediment erosion and deposition with DTM data, ONE-WAY ANOVA riverbed erosion and deposition of sediment within the variations, finally to get the best.
