T.Item ESTIMATING THE POTENTIAL FOR RAINWATER HARVESTING IN ILORIN, NORTH CENTRAL, NIGERIA(Federal University of Akure Journal of Engineering and Engineering Technology, 2024-09-01) Ayanshola, A. M.; Adidu, J.A.,; Iji, J.O.,; Oladimeji, S.B.,; Sule, B.F.,; Salami, A.W.; Bilewu, S.O.Abstract Rainwater harvesting is one of the viable ways of supplementing the surface and underground scarce water resources in areas where existing water supply system is inadequate to meet demand as being one of the potent measures for reducing impact of climate change on water supplies. The aim of this study was to estimate the rainwater harvesting potential of a typical house roof top in Ilorin Township for the purpose of supplementing household water needs. Ilorin has a mean annual rainfall of 1,244 mm which makes rainwater harvesting ideal. Intra annual variability lies between 0.04 and 0.4. Annually 590 m3 of rainwater can be harvested per household. Estimated annual water demand for flushing and laundry were 18, 24.12 m3, respectively. Harvested rainwater in Ilorin can meet household monthly water demand for toilet flushing and laundry except for December. The excess rainwater stored in September and October is enough to supplement the short fall in the dry months provided there is adequate storage. Water savings potential is highest in June and September which is the two-rainfall peak period in Nigeria.

A.Item Probabilistic Analysis of Peak Daily Rainfall for Prediction Purposes in Selected Areas of Northern Nigeria(Nigerian Journal of Technological Research (NJTR), Federal University of Technology, Minna, 2016-06-05) Salami, A. W.; Aremu, A. S.; Ayanshola, A. M.; Abdulkadir, T. S.; Garba, M. K.In this study, probability analysis was performed on peak daily rainfall data in order to predict rainfall interval values and to determine the best fit functions in some parts of Nigeria. The selected towns are Kaduna, Kano, Yola, Jos, Damaturu and Maiduguri. The obtained peak daily rainfall values were subjected to Gumbel, Log-Gumbel, Normal, Log-Normal, Pearson and Log-Pearson probability distributions. Mathematical equation for probability distribution functions were established for each town and used to predict peak rainfall. The predicted values were subjected to goodness of fit tests such as Chi-square, Correlation Coefficient, Coefficient of Determination and Errors of Estimates to determine how best the fits are. The model that satisfies the tests adequately was selected as the best fit model. The study revealed that the peak rainfall at Kaduna, Jos, Kano, Yola and Damaturu are best fitted by log-Gumbel, while log- Pearson distribution is suitable for predicting peak rainfall in Maiduguri. The result also shows that the occurrences of peak daily rainfall depth of 100 mm and above are rare in the selected areas.Item A Rapid Health Impact Assessment of the University of Ilorin Dam(Faculty of Engineering, University of Nigeria, Nsukka, Nigeria,, 2017) Bilewu, S.
