Major challenge for managing the water resources facilities, in particular over ungauged basin with lack of datasets and analysis tools, is occurred with water related hazards by population growth, urbanization and climate change (Barthold et al., 2008; Winsemius et al., 2009). In 2014, Korea water resources corporation and Korea Meteorological Administration have been established the Hydrometeorological Cooperation Center to accomplish more effective water management for scarcely gauged river basins, where data are uncertain or non-consistent. HCC aims to interconnect between weather observations based on remote sensing data (i.e., GPM) and forecasting information, and hydrological model over sparse regions with limited observations sites in Korean peninsula, specifically ungauged basins located near the border such as Imjin River. The Hydromeorological Portal System over North Korea is built for data sharing by constructing a web based on quality assured data into one system to manage the optimal flood and drought control over the ungauged river regime. Furthermore, the satellite-derived precipitation data applied as input dataset to grid based rainfall-runoff model i.e., K-water Distributed Rainfall RUnoff Model (K-DRUM) in order to predict water level of the dam shared by the two countries.
