ABSTRACT

Recently, abnormal weather due to climate change is gaining more attention worldwide. The concern is arising about the future climate change phenomena and its effects, caused by accelerating global warming and disaster occurrences are increasing worldwide. In South Korea, yearly mean precipitation 1375.4mm in 2000 is increased by 19% compared to 1155.6 mm in 1910 because of the global warming caused climate change and torrential rainfall occurrence(more than 100mm per day) frequencies in last decade(1999-2008) 385 is increased by 1.7 times than the 222 of 1970-1980. Gangneung recorded maximum daily rainfall of 870.5mm during typhoon Rusa in 2002 which caused many damages. In 2011, 1285.3mm total rainfall was recorded due to torrential monsoon rainfall from early July to mid August and in July, Seoul and capital region's torrential rainfall exceeded the 100 year design frequency and flooding caused big property damages and deaths in the central region. Likewise, climate change is causing changes in the patterns of extreme rainfall occurrence frequency and intensity. IPCC report, extreme rainfall occurrence frequency increases because of the climate change. While planning for water resource structure, facts of climate change and extreme rainfall event is an important variable to be included in the flood defence infrastructure by water resource engineers since it is becoming reality now to consider climate change. This study is done to analyze the effect of climate change, especially, on rainfall in the Gangwon-Yeongdong area using the historical rainfall data and through interpretation of frequency analysis, the effect on designed rainfall is analyzed. This paper is arranged in the order by chapters: 1. Introduction, 2. literature review, 3. Methodology, 4. Application and results. finally, 5. Conclusion.
