Rainfall analysis for environmental applications in Maiduguri, Nigeria
Rainfall data for Maiduguri, the capital of Borno State in North-East, Nigeria, covering the period from 1927 to 1983 (57 years) was extracted from published literature and used in this study. The data was subjected to statistical tests for trends, inconsistency and stability. Six separate monthly series were created for the purpose of the analysis. All the series passed the trend test, which was based on the Spearman's rank correlation test. The F- and t-tests on the series showed consistency and stability of the variance and mean, respectively. It is therefore, concluded that the rainfall data can be used for further analysis and storm sewage facility design. Keywords : rainfall, trend, stationary, homogeneous, consistent Global Journal of Environmental Sciences Vol. 4(2) 2005: 155-159
