Rivers are one of the main surface water resources representing a geographical unit that fulfills wide array of economic and ecological values. Quality of river water is vital for health of river ecosystem and maintain its functions. Climate and altitude are 2 of the main natural factors that influence on quality of the river waters. The study assessedaltitudinal and temporal variation ofsurface water qualityin the Badulu Oya catchment. The main river of the catchment was categorized into 3 segments based on altitudinal gradient. Ten physicochemical parameters of stream water were monitored at 14 sampling locations along these segments every other month for 18-month period following standard analysis methods. Results revealed that the observed water quality parameters are significantly varying ( |
