Abstract

Characterization of climatic change of rainfall is very important since the longterm trend of rainfall will directly impact many aspects associated with available water resources. Longterm trends of annual and monthly rainfall and stream flow in South Korea were investigated using Mann-Kendall test. The longterm climatic change of summer rainfall pattern in South Korea was summarized as the total number of rain day decreases, nevertheless, the total amount of rainfall increases, and the total number of days, whose daily rainfall amount is greater than 80 mm, increases. Despite increment of rainfall amount, the longterm trend of mostly stream flow records did not show statistically significant trend, it means that there were few sites which have upward or downward trends satisfying significance level of 90%.
