摘 要:Introduction:Land use/land cover change can affect the ecological processes of an area such as hydrological *** change in the condition of water resources of an area could be a good indicator of changes in ecosystem function as a result of altered land use/land *** expansion in central Ethiopia is one of the recent land use/land cover changes causing controversy on its potential ecological *** study was designed to evaluate effects of three adjacent land uses/land covers,*** land,grassland and Eucalyptus woodlot on surface runoff in Meja River watershed,central ***:The rainfall amount at each study catchment was collected using the rain gauge installed to record daily rainfall *** three land use/land cover types in each study catchment were selected for comparison as *** replications of each land use/land cover were used forming a total of 12 runoff *** rainfall and runoff data were collected twice a day for 91 ***:The study found that land use/land cover significantly affects surface runoff generated from the *** runoff was recorded from cultivated *** was no significant difference on runoff volume between grassland and Eucalyptus ***:This shows that expansion of Eucalyptus on grassland could not have significant impact on surface runoff generation but if planted on previously farmland could reduce surface runoff.
