ABSTRACT

Rainfall has become a primary concern for flood control and effective water resources management. It is predicted that the reduction of available water resources due to climate change will exert a severe influence on human life. This study conducted a trend analysis on the annual rainfall, monthly rainfall, and monthly maximum rainfall at Andong Dam basin for 42 years from 1977 to 2018. Statistical hypothesis tests were performed by a nonparametric test because the rainfall data do not follow a particular probability distribution. This study utilized the Mann-Kendall test, one of the commonly used nonparametric testing methods, in order to analyze the rainfall trend variations. It is confirmed that the October rainfall and July maximum rainfall show an increasing trend according to the 5% confidence level. In addition, the August maximum rainfall reveals a decreasing trend according to the 10% confidence level.
