Bayesian Modelling of Suspended Solids in Oyo State Reservoirs

The importance of water in human life cannot be overemphasized. Today, we see numerous compounds in our water that pollute it. Among those pollutants is suspended solids which is normally caused by erosion runoff, human activity, algae or sediment disruption. This book was aimed at modeling suspended solids in the two major reservoirs in Oyo state (Asejire and Eleyele reservoirs). Bayesian inference was used for this study. Suspended solids in both reservoirs observed over a period of 200 months from 2003 to 2019 assumes Normal Distribution. A conjugate prior for normal density was used to give an update of knowledge about suspended solids inform of the posterior distribution with unknown mean and known precision. The posterior mean and precision for Asejire Reservoir is 40.572 and 0.00001634 respectively and that of Eleyele Reservoir is 74.598 and 0.0003375 respectively. In addition, the 95% credible interval was obtained for the two reservoirs.
