Abstract
Recently, there have been flood damages due to the climate change and the flash flood continuously in Korea and there are several flood disaster mitigation plans that are normally most of management plan for water related disasters even though drought disasters are as important as flood disasters. In this study, it is underlined that the research on solution of water shortness due to the drought disasters is currently required since the frequency of drought damage is not very many but continuously increasing. There was big drought damage in TaeBaek City of Kangwon province due to the serious lack of water during autumn, 2008 to spring, 2009. This study therefore analyses the characteristics of hydrometeorological conditions by rainfall frequency analysis and the operations of Gwangdong dam that is a source of multi-regional water supply by analysing water demand. As results of study, there was a drought with 20 years returning period which is not really available to fill the reservoir as usual and which could only filled 52% of reservoir. The rainfall during the dry season was less than normal, however, the water demand from the TaeBaek City was higher than normal. As researching several reasons of water shortness including the reasons described above, this study might be useful for drought mitigation plan.
