ABSTRACT Typhoon-induced storm surge along with heavy rainfall has been recognized as the most frequently reported hazards for water-related hazards in South Korea. Moreover, it has been widely acknowledged that the frequency and intensity of typhoons (or abnormal low-pressure system) are likely to increase over time due to the potential impact of climate change. There are 14,000 small reservoirs in South Korea and various issues related to the reservoir safety. A hydrologic reservoir risk analysis requires a systematic process to ensure dependency relationships among key hydrologic variables (e.g. precipitation, * A DEVELOPMENT OF HYDRAULIC-HYDROLOGIC RISK ANALYSIS MODEL FOR SMALL RESERVOIRS BASED ON BAYESIAN NETWORK 1043
