Journal Title: Analele Universitatii din Oradea, Seria Geografie - Year 2017, Vol 27, Issue 1
Abstract
This study examined the differences between the qualities of surface water traversing the various land use types within Ibadan metropolis, South-Western, Nigeria. And identified the pattern of distribution and compared the concentration of some of the chemical and physical components of the surface water with a view to determining the impact of human activities on the concentration of both the physical and chemical components of water within the study area. The study integrated a topographical map of 1965 and Google Earth satellite images of 2.5 m spatial resolution coupled with intensive fieldwork. Four rivers that traversed the metropolis were purposively selected for this study from where a total of twenty samples was collected with five samples from each stream that traverse the various land use types using Global Positioning system for the transfer of coordinates to the sample points. Data collected was analyzed using descriptive statistics, analysis of variance, simple linear regression analysis and geospatial techniques coupled with laboratory analysis of samples collected. The result showed a significant relationship between residential and commercial land use and surface water quality change (0.02, 0.013; P<0.05). The study concludes that commercial and residential effluents has strong negative impact on the surface water quality change compare to industrial and agricultural land use in the study area.
