ABSTRACT

Base Flow Index(BFI) is a key catchment characteristic for water resource management. This study estimates the BFI at 24 Guem-river catchments with observed stream flow data and suggests the formular of BFI based on Catchment Characteristics. The results of BFI shows that BFI has wide variation in the value of between 0.08(Tanbu-gyo) and 0.72(Yongdang-dam). these results indicate that Hapgang, the catchment with large reservoir, has very high BFI values and the highland mountain catchment, such as Tanbu-gyo, has smaller values of BFI. The result of suggested formular is compared with estimates one at Seokdong catchment. It indicated that the suggested BFI formular has a potential in catchment characteristics for Guem river region.
