HS04.01 Subsurface hydrology: Model validation and calibration in surface and subsurface hydrology: connecting measurements, theoretical models and applications

Event Information

Physically-based models are fundamental tools for describing the behaviour of natural systems and for predicting the evolution of the state of natural resources. A physically based model is formulated by describing the system it represents with mathematical equations. The values of the parameters that appear in these equations need to be determined through calibration. Subsequently the model needs to be validated. Then, the model can be used for its intended purpose, e.g., evaluating different scenarios for future developments. These steps (formulation, calibration, validation, and application) are universal, but their practical realisation varies widely and depends on the scale(s) of interest, available data and resources, required accuracy of the calculations, etc. We invite presentations that are related to any step or combination of steps in subsurface hydrology. Some topics of interest are: (1) model calibration, i.e., development and application of methods for the identification of model parameters. (2) model validation, i.e., establishing the ability and adequacy of a model for making predictions; (3) comparing model predictions to measurements; (4) scale effects on the physical laws governing subsurface hydrology and on the physical parameters; (5) integration of hard and soft (geological, geophysical,...) data for parameter identification; (6) quantifying the uncertainties of physical parameters and the uncertainties of predictions."
