Characterization of Parameter Uncertainty in SWAT Model using MCMC Bayesian Framework: The Case of Naryn River Basin

Analysis of parameter uncertainty in distributed watershed model is a worldwide challenge. In this study, The Differential Evolution Adaptive Metropolis (DREAM) technique is developed to analyse the uncertainty of Soil and Water Assessment Tool (SWAT) model parameters. SWAT is used for providing the basic hydrologic simulation, DREAM algorithm is employed to approximate the posterior distributions of model parameters with Bayesian inference. …
