Abstract: Groundwater model of heterogeneous media and its scarcity of observation data and other related factors makes the existence of uncertainty. In order to better predict the output of the model, we need to estimate the input and parameters of the model based on limited observational data to re-duce the uncertainty. Bayesian method is an effective way to describe the uncertainty caused by incomplete data, model deviation and measurement error. It can determine the posterior distribu-tion of parameter vectors according to the existing data...
