Abstract: In recent years, precipitation patterns have changed dramatically around the world, and securing stable water resources is becoming increasingly difficult due to the increasing frequency of droughts caused by climate change. In the case of precipitation patterns, they are changing significantly in regional and temporal terms. In South Korea has experienced a multi-year drought that is rare in the past over the past decade. The Water shortages occurred mainly in the Boryeong Dam in South Chungcheong Province from 2015 to 2019 and in the Yeongsangang River and Seomjingang River basins from the second half of 2022 to the first half of 2023. As the number of basins vulnerable to drought gradually increases, it is necessary to develop different measures and technologies to efficiently connect the water supply network to water facilities across the country through water shortage areas and solve future water supply vulnerabilities. Therefore, we developed an Emergency Response Decision Support Platform (ER-DSP) for water shortage to help stakeholders make decisions in emergency situations. It can assess risk based on drought severity and simulate interregional water allocation using the Water Allocation Model (WAM) based on drought scenarios. Thus, we built a platform that integrates a Shared Vision Model (SVM) to reflect mutual feedback and decisions in quasi-real time and share water supply outlook information to build a more efficient and optimal decision support system. We expect that, based on this study, a decision-making supporting platform can be provided to computerize the inter-ministerial cooperation system and related technologies, rationally allocate water, and build an efficient water supply system in order to respond to water shortage emergencies.
