ANALYSIS OF FLOODPLAIN ENCROACHMENT PATTERN AND MANAGEMENT IN KADUNA METROPOLIS

📄 Project Abstract

Rivers and their floodplains have always served as physical limitation to the spatial growth of urban centres located along river course. The rapid growth and expansion of these urban centres have always resulted to encroachment of urban activities on floodplains with increase in vulnerability to flood disaster. Therefore the monitoring of urban growth and changes along these river floodplains are of concern to the physical planner and urban managers who must understand the urban growth dynamics and manage resources while providing service to these rapid changing environments. This research therefore analysed the spatial growth of urban built encroachment and management on river floodplains in Kaduna metropolis. In conducting the research, river floodplains as identified by the 1967 Max lock master plan of Kaduna were delineated and mapped out from digital elevation model (DEM) using ArcGIS 9.3. Satellite images of 1990, 2000, and 2012 time epoch were then used to establish the encroac...
