Description
The inclusion of additional information in a model should improve it's performance and reduce associated uncertainties. The additional information may take the form of higher temporal and/or spatial resolution of data already used, or additional (potentially soft) data. However, additional data is not necessarily equivalent with additional information, or with information that can be used by a particular model. Consideration of the information-to-noise ratio is needed in order to evaluate whether the information will indeed improve the model's ability to simulate the system. Evaluating the information-to-noise ratio and the information content of data in general are difficult, but one possible approach is to compare the performance and uncertainty of a model with and without the additional information. This session/workshop will focus on the use of additional information in improving the performance of and reducing the uncertainty in hydrological models. This includes consideration of the uncertainty in datasets as well as techniques to evaluate the effectiveness of the additional information in improving models.
