本計畫目標係發展適用於台灣河川水體之底泥品質分布預估模式與預防管理平台，藉由模式模擬結果，評估釐清河川各河段之底泥污染潛勢程度，據以提出相對應之管理作為。盤點台灣１１８條列管河川資料及依模式模擬優先次序篩選機制，篩選１２條優先評估水體，於其中研選阿公店溪與老街溪為示範水體，以WASH123D進行模式建立與參數率定驗證後，依據模擬結果建立集水區底泥污染潛勢圖，由結果可知阿公店溪土庫排水、本洲工業區放流及永安工業區放流匯入後河段為高污染潛勢河段，老街溪大坑坎溪及大園一期工業區與田心仔溪等污染源匯入後等多處河段為高污染潛勢河段。針對高污染潛勢河段，建議加強高污染潛勢河段周邊工廠之事業排放廢(污)水稽查，以及重要污染介入點對應之集污區劃定總量管制區、沼渣沼液資源化、加嚴排放標準。

The goal of this project is to develop a contaminated sediment transport model and preventive management platform suitable for river water bodies in Taiwan. Based on the model simulation results, evaluate and clarify the potential degree of sediment pollution in each river section of the river, and then propose the corresponding management as. Through the existing data inventory and model simulation priority screening mechanism of 118 listed rivers in Taiwan, 12 priority water bodies were selected for evaluation. The Agongdian River and the Laojie River were chosen as the demonstrated water body among those 12 rivers mentioned above. After the model is established by using WASH123D and the parameters are calibrated and verified, the sediment management dashboard of the model platform is used to establish the potential map of sediment pollution in the river catchment area, to grasp the spatial pollution status of the sediment quality of the demonstration water body. From the results, it can be seen that the Tuku river reaches, the discharge from the Benzhou Industrial Zone and the discharge from the Yongan Industrial Zone are the high pollution potential river reaches for the Agongdian River. Many river sections such as Laojie River, Dakeng River, Dayuan Phase I Industrial Zone and Tianxinzai River and other pollution sources are high pollution potential river sections. For high pollution potential river sections, it is recommended that the competent authority of the target industry increase the frequency of sediment sampling in accordance with the "Measures for the Classification and Management of Sediment Quality Indicators and Restrictions on Uses", and recommends strengthening the inspection of industrial waste (sewage) water discharged by factories around the high-pollution potential river section, and to delineate total control areas, resource utilization of biogas residue and biogas slurry, or tighten discharge standards for pollution collection areas corresponding to important pollution intervention points.
