降雨遷移對集水區BMP配置之影響

本研究之目的在探討由非點源污染所引起之集水區水質污染,非點源污染問題日趨嚴重。往往由於一場暴雨或多場所帶來各種污染物會隨著河水逕流的不規則移動,造成污染的分散。本案例設計一虛擬集水區流域劃分為九個子流域,暴雨初期沖刷是集水區水質是否或受到污染的關鍵時刻,在不同的降雨特性下以及不同地形下如草溝或滯留池,引起的汙染物對於各項水質濃度將產生影響以及改變。

在BMPs 測試方面,設計虛擬集水區內之土地,並利用滯流池及草溝對非點源污染控制之模擬測試,應用WinVAST模式資料庫及演算功能,藉此瞭解不同之BMPs在不同降雨特性及不同最佳管理措施(滯留池+草溝)去除非點源污染之效率,並了解各污染物的濃度變化情形,取得經濟化配置設計效果。

關鍵字:非點源污染、BMPs、草溝、滯留池、WinVAST

    Rain to move to gather water area BMP the influence of the allocation

    The purpose of this research is inquiring into by don't order a source pollution cause it to gather water area fluid matter pollution, don't order a source pollution's problem gradually serious.Usually bring the irregular ambulation that various pollutant will directly flow along with river water and cause polluting dispersion due to a rain-storm or many places.This case designs a conjecture gather water area river valley to divide the line to nine statures river valleys, the rain-storm flushed in the early years is gathered water area fluid matter whether or was subjected to a polluting turning point, under the different rainfall characteristic and under the different geography as grass ditch or was detained pool, the pollution thing causing influences a creation and changes to various fluid matter densities.

    Test aspect in BMPs, the design conjecture gathers the land in water area, and makes use of Zhi to flow pool and grass ditch to don't order a source pollution control of emulation test, the mode database of application WinVAST and calculation function, with this understanding different BMPs cleans and doesn't order a source pollution in the different rainfall characteristic and the dissimilarity best management measure(be detained pool+grass ditch) of efficiency, and obtain economy to turn the effect of the allocation design as for the situation of the density variety that understand each pollutant.

    Key word:Don't order a source pollution, BMPs, grass ditch and be detained pool and WinVAST

    Rainfall on the relocation of the catchment area of the impact of BMP-targeted

    The purpose of this study to investigate the non-point source pollution caused by water pollution of water catchment areas, non-point source pollution problems getting worse. Often because of a rainstorm or more places will bring all kinds of pollutants as the irregular movement of water runoff, pollution caused by the dispersion. In this case a virtual design district catchment basin is divided into nine sub-basins, heavy rain washed away the early water catchment area is contaminated or whether the critical moment, the rainfall in different characteristics and under different terrain such as grass ditch or stranded pool, caused by For the concentration of pollutants will have an impact on water quality and change.

    BMPs in testing, design virtual catchment areas of land and use of stagnation flow pool and grass ditch on the non-point source pollution control simulation tests, applications WinVAST model database functions and calculus to understand the difference between rainfall in different BMPs And the different characteristics of the best management practices (+ grass ditch stranded pool) unless the point source pollution to the efficiency and understand the changes in the concentration of pollutants, the economic effects of the configuration design.
