“…While the increase in water availability during the rainy seasons may result from higher rainfall, increased flow, and decreased evapotranspiration. This study confirms findings of [ 22 , 23 ] that flow in the gauged Lake Tana watersheds could drop during the dry season and increase during the wet season under RCP4.5 and RCP8.5 scenarios for the 2040s and 2070s periods. Additionally, the outcome differed from Ref.…”

“…So far, plenty of studies have been conducted regarding the adverse impact of climate change on watershed hydrological processes, water resources availability and its sustainability across the globe (Namara et al 2022;Olsson et al 2016;Tabari 2020;Tarekegn et al 2022). For instance, Wubneh et al (2022) conducted the hydrological impact of climate change in Tana sub-basin, Ethiopia. From their study they concluded that streamflow is showing an oscillating trend which means decreasing over the dry season and increasing over the wet season.…”

Climate change is one of the most challenging and inevitable global environmental problems affecting mankind and its environment regardless of urban and rural areas. Its effect on watershed hydrology is challenging the sustainable water resources management and its availability across the globe. In order to develop a sustainable climate change adaptation strategy, understanding watershed hydrological response to the ever increasing climate change is highly important. Hence, the main objective of this study was investigating role of watershed hydrological response in developing climate resilience and adaptation strategy as a case study in Gilgal Gibe watershed, Omo Gibe river basin, Ethiopia. To achieve the main objective of the study, three regional climate models (RCM) derived from one global climate model (GCM) under two greenhouse gas emission scenarios (RCP4.5 & RCP8.5) were collected from CORDEX Africa. These data were analyzed against the 1986–2016 baseline data and projected for near future term (2020–2050) and for near future term (2051–2080). The climate dataset trend analysis over the specified period was conducted using Mann-Kendall test and the hydrological modeling was performed using the calibrated and validated HEC-HM model. From the analysis it was found that hydro-climate variability over the proposed time horizon was clearly observed from all RCM under both greenhouse gas emission scenarios. The stream flow revealed an oscillating trend over the course of the operation years under RCP4.5 and RCP8. Hence, this information is important for water resources manager, decision makers and policy makers to develop sustainable climate change resilience and adaptation.
