Investigation of the spatial and temporal long-term hydro-climatic trends in Upper Omo Gibe Basin, Ethiopia.

ABSTRACT: Human activities have changed hydroclimatic components worldwide, affecting agricultural productivity and water resources management. This research examined the spatial and temporal variability of hydroclimatic variables in the Upper Omo Gibe Basin. Modified Mann-Kendall, Sen's slope, and Innovative Trend Analysis methods were used to study the trends. The maximum statistically significant increasing trend of rainfall (P < 0.05) was observed at Limugenet station (Z = 3.641, S = 16.484), and a decreasing trend of rainfall was observed in Dedo station (Z = -2.732, S = -31.099). A generally decreasing rainfall trend was observed in the Upper Omo Gibe Basin. Temperature showed an upward trend in seasonal and annual observation. In spring, summer, autumn, and winter seasons the maximum signific
