"Breakthroughs in Process-Based Hydrological Modeling"
We all use models in our research to synthesize observations, evaluate what-if scenarios, forecast ex- tremes, and test our understanding of hydrological processes. We each tend to have our favorite models, with model selection dictated as much (or more) by familiarity and allegiance as by model suitability for the application at hand. With this choice (or perhaps default selection) of any given model, we inherit many implicit assumptions about the functioning of hydrological systems as codified by model devel- opers. A number of initiatives address this model selection challenge by allowing the user to construct distinct hydrological models within a single model framework, thereby enabling the user to evaluate the impacts of changes in the model parameters, parameterizations and spatial arrangements on hydrolog- ical quantities of interest. In this presentation, I will discuss recent advances and breakthroughs in pro- cess-based hydrological modeling and model evaluation using one of these frameworks: The Structure for Unifying Multiple Modeling Alternatives or SUMMA.
