Elements of a flexible approach for conceptual hydrological modeling: 1. Motivation and theoretical development

This paper introduces a flexible framework for conceptual hydrological modeling, with two related objectives: (1) generalize and systematize the currently fragmented field of conceptual models and (2) provide a robust platform for understanding and modeling hydrological systems. In contrast to currently dominant “fixed” model applications, the...

Elements of a flexible approach for conceptual hydrological modeling: 2. Application and experimental insights

In this article's companion paper, flexible approaches for conceptual hydrological modeling at the catchment scale were motivated, and the SUPERFLEX framework, based on generic model components, was introduced. In this article, the SUPERFLEX framework and the “fixed structure” GR4H model (an hourly version of the popular GR4J model) are applied...

Pursuing the method of multiple working hypotheses for hydrological modeling

Ambiguities in the representation of environmental processes have manifested themselves in a plethora of hydrological models, differing in almost every aspect of their conceptualization and implementation. The current overabundance of models is symptomatic of an insufficient scientific understanding of environmental dynamics at the catchment...
