Global Climate change has been discussed in the High-Level Conference in Rio de Janeiro, Brazil in 1992 and has given more impacts in the world. One of the global climate exchanges is the rising of intensity and frequency of climate extreme which included drought, flood, and hurricane. The objective of this study was to investigate the effects of climate change on evapotranspiration and rainfall for river water discharge of Rawa. The investigation has been carried out using daily data and analyzed on a daily, monthly and yearly. The rain stations that represent the location of this research are Palolo, Kulawi, and Wuasa. Climatological station nearest to the research station used Bora. Climate trends and projected changes in the method of Makesens analysis (Mann-Kendall, Sens) and the correlation of rainfall and evapotranspiration discharge used linear regression equation. Similarly, the correlation between changes in soil water storage with rainfall, evapotranspiration, and discharge was analyzed in a linear manner. The conclusion of this study is the climate changes in the River of Rawa watershed was characterized by slowly increasing temperature, increasing rainfall, and decreasing discharge.
