Classical and Bayesian Markov Chain Monte Carlo (MCMC) modeling of extreme rainfall (1979-2014) in Makurdi, Nigeria

This study presents a probabilistic model for daily extreme rainfall. The Annual Maximum Series (AMS) data of daily rainfall in Makurdi was fitted to Generalized Extreme Value (GEV) distribution using Maximum Likelihood Estimation (MLE) and Bayesian Markov Chain Monte Carlo (Bayesian MCMC) simulations. MLE is a reliable principle to derive an efficient estimator for a model as sample size approaches infinity. Results in...

A challenge of sustaining water supply and sanitation under growing population: A case of the Gezira State, Sudan

The challenge of securing future water supply and sanitation services for an increasing population requires continued efforts to satisfy the future needs. This paper focuses on water availability and sanitation services under growing population taking Gezira State, Sudan, as the case. Future projection of the population was predicted based on the 2.2% growth rate. Data on water sources, quantities and sanitation was...
