ABSTRACT

Morphological studies in semi-arid urbanizing watersheds reveal varying responses that describe rapid channel adjustment often with adverse economic and environmental consequences. This study assessed spatial dimension of Ginzo catchment response to urbanization in Katsina Metropolis, Nigeria. Morphometric parameters were obtained through direct field measurements while degree of urbanization in each of the three segments of the river channel was computed from satellite imagery of Katsina metropolis. Descriptive statistics like mean, standard deviation, coefficient of variation, percentages and line graphs were then used in the analysis of data generated from the field. The study revealed that channel width were lowest at the upstream (11.2m) and highest at the downstream section (28.9m). Moreover, mean channel depth were lowest at the midstream (0.34m), and highest at the downstream section (1.45m) while channel cross-sectional area were lowest at upstream (15.40m2 ) and highest at the midstream (61.55m2 ). The results indicate that channel segments respond differently to different level of urbanization. The study therefore, recommends integration of geomorphic knowledge in urban and water resources policy of Nigeria. These include the use of bio-engineering approach in channel management and review of environmental policies to control channel encroachment.
