Résumé

Droughts are natural disasters that greatly affect the environment, the ecosystem and water resources. The objective of this study is to analyze the impact of climate change on hydrological droughts and predict future hydrological droughts using the SRES A1B scenario of IPCC AR4 and KMA(Korea Meteorological Administration) RCM climate models. Future droughts are analyzed by considering the joint probability distribution derived by applying the copula method. Results of this study show that severe droughts of short durations will occur more frequently in the near future. In order to determine drought frequencies in the future, SDF (Severity-Duration-Frequency) curves are suggested.
