Coupled hydrogeophysical parameter estimation using a sequential Bayesian approach
hydrogeophysical parameter estimation sequential Bayesian approach
2010/4/7
Coupled hydrogeophysical methods infer hydrological and petrophysical parameters directly from geophysical measurements. Widespread methods do not explicitly recognize uncertainty in parameter estimat...
Investigation of a parameter estimation method for contaminant transport in aquifers
Investigation parameter estimation method contaminant transport aquifers
2009/12/4
Real world groundwater aquifers are heterogeneous and system variables are not uniformly distributed across the aquifer. Therefore, in the modelling of the contaminant transport, we need to consider t...
Sensitivity analysis and parameter estimation for distributed hydrological modeling：potential of variational methods
Sensitivity analysis distributed hydrological modeling singular value decomposition
2009/4/28
Variational methods are widely used for the analysis and control of computationally intensive spatially distributed systems. In particular, the adjoint state method enables a very efficient calculatio...
Influence of parameter estimation uncertainty in Kriging: Part 2 - Test and case study applications
