This chapter describes how, notwithstanding the many possible applications of inverse modeling in the modeling of fate and transport processes in the soil-crop continuum and the many advantage of inverse approaches as compared to classical identification techniques, little attention is given to the performance properties of the inverse modeling that determines the success or failure of an inverse approach for a given application. This chapter reviews some basic principles of the inverse modeling approach and illustrates the method for identifying unsaturated flow, transport, and crop parameters of the soil-crop continuum. Particular attention is given to the properties of the forward mode, the objective function, and the optimization algorithm, which determines the robustness of the inverse approach. In addition, performance evaluation techniques are presented in the chapter, which allow one to quantify the performance of the inverse method in an objective and transparent manner.
