TL;DR: General classes of direct value comparison, coupling real and modelled values, preserving data patterns, indirect metrics based on parameter values, and data transformations are discussed.

TL;DR: The GR4J model as discussed by the authors is a daily lumped rainfall-runoff model which is the result of a continuous improvement process over the last 15 years, and it provides the mathematical formulation of a new four-parameter version of the model.

TL;DR: In this paper, the most relevant approach to calculate potential evapotranspiration (PE) for use in a daily rainfall-runoff model, while answering the following question: How can we use available atmospheric variables to represent the evaporative demand at the basin scale?

TL;DR: In this article, the authors present an historical perspective of the controversy concerning the hydrological impact of forests, and show how a mostly romantic and emotional confrontation finally evolved into a scientific debate.

TL;DR: In this article, the authors examine the role of complexity in hydrological models by studying the relation between the number of optimised parameters and model performance and conclude that an inadequate complexity typically results in model over-parameterization and parameter uncertainty.
