Numerical methods for optimization problems in water flow and reactive solute transport processes of xenobiotics in soils (Q2724090)

The author presents efficient and reliable methods for both parameter estimation and optimal experimental design in water flow and reactive solute transport processes in soils described by nonstationary partial differential equations coupled with ordinary differential equations. In particular, the tools ECOFIT and ECOPLAN have been developed supporting the inverse modeling approach for the purpose of registration. The tool ECOFIT provides a reliable solution for inverse modeling in water flow and reactive solute transport processes, whereas the tool ECOPLAN is well suited for optimal experimental design of column and lysimeter experiments that allows to simultaneously optimize experimental conditions and sampling schemes.
