四重溪流域受民國84年牡丹水庫興建完成及歷次風災如民國98年8月莫拉克等，本河系(含主、支流源頭起點至出海口及水庫)因雨勢過大，造成河川水文、地文及河川區域人工構造物等產生重大的改變及破壞，同時影響本河系之環境生態及生物棲地發生明顯的變化，因此有必要針對本河系進行全面性環境生態及河川情勢之調查，以瞭解河川環境及生物相特性，並依據本河系環境生態及生物棲地提出河川環境管理建議，建置生態資源資料庫，供工程單位規劃設計人員參考，以降低未來治理工作對生態環境之衝擊

River development and management in Taiwan before over-emphasized water treatment engineering, but less considered the whole environmental ecology. In recent years, since environmental protection consciousness has been more and more important, there is a need to do more investigation to make up the shortage of existing material which should be integrated for the reference of public. To promote river business, river management, environmental conservation and rehabilitation, and provide the reference of natural treatment design for hydraulic engineering institute, all the basic material including Humanities, physiographic, hydrological data, biological, space utilization need to be collected in this project. The project is to investigate river situations, including Sihchong River. The work target is to compile GIS ecosystem data as unit of river for the whole Sihchong Rivershed and to build it into the database at the website for the Management Information System of River’s Investigation.
