Abstract

The increasing rate of urban growth and expansion has adverse effects on the landscape features of urban areas, which significantly impacting on land use and land changes along drainage channels. This study examined the dynamics of Land Use and Land Cover along Drainage Channels in Port Harcourt Metropolis, Rivers State, Nigeria. The adopted the longitudinal research design employing the use of geographic information system (GIS) in collecting geospatial data using multispectral and geospatial technologies for inputting data sets obtained from the United State Geologic Survey on the Land Sat Imagery of Port Harcourt drainage system. The data were analysed using geospatial technologies. Findings of the study revealed that farm land and built-up areas increased greatly while water bodies, riparian or swamp forest and thick forest reduced in spatial extent along the drainage channels within the buffer of 200m, 400, and 600m from 1990 to 2022. The study recommend for the preservation and conservation of natural vegetation which include the thick vegetation and riparian/swamp forest in the flood plain buffer along the stream channels to slow and prevent rapid generation of runoff and flood occurrence.
