ABSTRACT

The paper assesses the impact of urbanization on the landform parameters of Ado-Ekiti city. Data were collected directly from the field on variables such as the river channel morphometry, number of potholes, number of refuse dump sites, depth of foundation exposure, depth of sediment in storm drains and extent of road width covered with sediment among others. The basic instrument employed for carrying out the measurement are the tape, a tie-rod, and ranging pole. Analysis of the data using the descriptive method of frequency counts and percentage ratings showed that the impact of urbanization includes modification of river and stream channels, sedimentation/fragmentation of riparian vegetation, headward advancement of gully and erosion channel and excavation of the foundations of buildings among others. The paper suggests measures for controlling the various geomorphological impacts of urbanization in the city to include channelization of the streams, effective management of slopes, construction of storm drains of adequate number and hydraulic capacity and provision of proper waste management measures, among others.

Key words:Assessment, Geomorphological, Impact, Urbanization, Ado-Ekiti and Nigeria.
