  "abstract": "<p>Urbanization along with its impervious structures is the major challenge of urban<br>\ncenters. The foundation and expansion of Addis Ababa was associated with the rapid<br>\nconversion of land from rural to urban uses more than anywhere else in the country. For<br>\nthe last one hundred twenty years it has been noticed that there is an intensive<br>\nconversion of rural land to urban development such as buildings, transportation<br>\nnetworks, recreation areas, reservoirs and others where most of them are impermeable.<br>\nThis study has investigated the overall environmental challenges of the urban drainage<br>\nsystem. This study has particularly carried out in three sample kebeles (kebele 01/02,<br>\n08/15 and 13/14) within Yeka sub-city. These kebeles were selected because of the fact<br>\nthat they are representative to address the objectives of this study. Deforestation and<br>\npavement of structures are the major problems in the study area. An exploratory and<br>\nDescriptive type of research design methods were used to describe and explore the<br>\nexisting condition of the general urban drainage system and the natural water ways.<br>\nData collection methods were carried out using both primary and secondary data<br>\nsources. The secondary data source was only relevant to reinforce the primary data.<br>\nThe collected data were analyzed with Ms-excel, AutoCAD and ArcGIS. The results<br>\nhave been presented with known statistical tools.</p>",
