Table 1 Precipitation stations and their missing Values
Likewise, daily data of seven streamflow gauging stations (Table 2) within the basin collected from the Ministry of Water and Energy. These daily data are converted to monthly based to evaluate its seasonal flow fluctuation. So, upper Awash basin river flow fluctuation is evaluated from the study time-series change in streamflow. Hence the climate change is possibly manifested in the change of precipitation that believed to be observed in streamflow regime change according to section 2.2.5.
