This paper is principally aimed to express some hydrological aspects regarding to the 2006‐2007 time series investigation within Bribin River system. The concept of karst watershed and the Bribin System historical review is firstly presented in order to give the understandable viewpoint with reference to hydrological investigation conducted in this site. Afterwards, this paper illustrates some aspects of 2006‐2007 Bribin System investigation such as site selection, equipments, measurements, and spatial‐temporal results on discharge fluctuation, karst flow component ratio, and rainfall intensity. Lastly, this paper also evaluates the 2006‐2007 investigation constriction and gives some recommendations related to the next Seropan River System study
