Information - HS4/9 Hydrological modelling strategies across scales: Model parameterisation, comparison and ensembles
Modelling of catchment hydrological processes has become essential for addressing science as well as practical management questions. On the one hand the evaluation of hydrological catchment models and the underlying uncertainties has become more important in recent years, whereas on the other hand the comparison of models for distinct purposes has moved into the focus of interest. Following developments in meteorology, hydrologists have started to compare different models of the same type (e.g. distributed) or different types of models (e.g. distributed vs. lumped, process based vs. conceptual), to apply more than one model to predict catchment hydrological processes and to use model ensembles to calculate environmental and climate change scenarios. These activities often aim on making better predictions as well as understanding the functioning and advantages of single models and model ensembles. Against this background, this session welcomes contributions which focus on the following issues:
- Comparison of hydrological catchment models for distinct purposes: which model is more appropriate for a particular question (e.g. prediction of water availability or flood peaks) than another, including discussions on advantages and disadvantages of the models? Comparisons of similar model types as well as different model types (conceptual, process based, distributed, lumped) are welcome!
- Use of several different models and/or model types to better predict water fluxes in catchments.
- Application of model ensembles for improved predictions of hydrological processes.
- Innovative or existing methods to combine individual model predictions into a model ensemble.
- Analyses of the (dis-) advantages and possibilities of model ensembles in catchment hydrology.
