홍수 방재를 위한 레이더 강우 예측 및 평가에 관한 연구 = A Study on Radar Rainfall Prediction and Evaluation for Flood Disaster Prevention

다국어 초록 (Multilingual Abstract)

Due to the recent climate change, the frequency of heavy rains is increasing, and have sudden and local characteristics in urban areas, so the damage to life and property is also increasing, and it is structurally vulnerable to floods due to rapid urbanization. In this study, in order to evaluate the usability of flood disaster prevention of radar rainfall, the rainfall radar of the Ministry of Environment was used to evaluate the accuracy of radar observation rainfall with the rainfall at the point of the rain station in Jeonha-dong in Busan for 6 rainfall events, including typhoons and stationary front that occurred from 2019 to 2021. In addition, predicted rainfall was generated by using a translation model that predicts rainfall while moving the rainfall distribution according to the translation vector by extrapolating time series radar data, and the accuracy of predicted rainfall was evaluated by comparing it with the ground-observed rainfall. As a result of radar rainfall observation and prediction accuracy evaluation, it was confirmed that sufficient accuracy was shown in utilizing rainfall radar data in the flood disaster prevention area.
