Drought severity-duration-frequency analysis of hydrological drought based on copula theory
Recently, in Korea, occurrences of floods and droughts have been increased due to the climate change and drought is a recurrent phenomenon. But, recurring prolonged droughts have caused consequences and diverse impacts on human system. Therefore, understanding drought characteristics is indispensable element in well-prepared drought management. This study aims to investigate the hydrological droughts of upstream of Namhan river in Korea. For modelling of the joint distribution of drought duration and drought severity, the copula method is used to construct the bivariate drought distribution and ...
