Abstract
The data of stream gauging stations connected to the upper and lower stream have similar hydrological characteristics. It is also veryimportant data for disaster management. In this study, we suggest a methodology which is used to build an optimal stream gauge networkfor mitigating the flood risk of a disaster risk area by adding new stream gauges at disaster risk areas to the existing streamgauge network. The upper stream basin of Geum river was selected as a study area. Representative unit hydrograph was estimated byClark method in each station. And the information transmission by entropy analysis were evaluated based on the log-normal distribution.
The optimized stream gauging networks about three scenarios of the gauging stations were determined using the entropytheory. Finally the most important gauging station was selected using the received information transmission in each disaster risk areaand the whole basin.
