Abstract
Water is vital for any life process and there can be no substitute for it, and water serves many other useful purposes. Water supply to residents in Osun State is inadequate due to non-existence of schedule planning for water abstraction by related body. This study investigated the development of an optimization model for water abstraction on River Osun. The model developed was a linear regression approach considering the effects of previous and current water abstraction. Fifty (50) years rainfall data collected from 1963-2012 were used to estimate corresponding runoff using rational approach method. The rainfall intensities were regressed against runoff and the corresponding generated runoff arrived at correlation co-efficient of 0.762 and 0.770, respectively. The water abstraction based on optimization model could serve as a hydrological input in the development of water abstraction by related body on River Osun. The developed optimization model is useful for effective river abstraction quantification.
