    <dct:description>&lt;p&gt;Urbanization along with its impervious structures is the major challenge of urban&lt;br&gt; centers. The foundation and expansion of Addis Ababa was associated with the rapid&lt;br&gt; conversion of land from rural to urban uses more than anywhere else in the country. For&lt;br&gt; the last one hundred twenty years it has been noticed that there is an intensive&lt;br&gt; conversion of rural land to urban development such as buildings, transportation&lt;br&gt; networks, recreation areas, reservoirs and others where most of them are impermeable.&lt;br&gt; This study has investigated the overall environmental challenges of the urban drainage&lt;br&gt; system. This study has particularly carried out in three sample kebeles (kebele 01/02,&lt;br&gt; 08/15 and 13/14) within Yeka sub-city. These kebeles were selected because of the fact&lt;br&gt; that they are representative to address the objectives of this study. Deforestation and&lt;br&gt; pavement of structures are the major problems in the study area. An exploratory and&lt;br&gt; Descriptive type of research design methods were used to describe and explore the&lt;br&gt; existing condition of the general urban drainage system and the natural water ways.&lt;br&gt; Data collection methods were carried out using both primary and secondary data&lt;br&gt; sources. The secondary data source was only relevant to reinforce the primary data.&lt;br&gt; The collected data were analyzed with Ms-excel, AutoCAD and ArcGIS. The results&lt;br&gt; have been presented with known statistical tools.&lt;/p&gt;</dct:description>
