airGR: a suite of lumped hydrological models in an R-package

The GR hydrological models

The GR models were designed with the objective to be

as efficient as possible for flow simulation at various time steps, ranging from hourly to interannual (Perrin et al.,

2009).

The model structures were developed with the intention to have warranted complexity and limited data

requirements. The models can be applied on a wide

range of conditions, including snowy catchments thanks to the CemaNeige snow routine.

GR is a family of lumped hydrological models designed for flow simulation at various time steps.

The models are now available in a flexible R-package called airGR (Coron et al., 2016, in prep.).

The models can easily be implemented on a set of catchments with limited data requirements.

Schematic diagram of the GR models

The airGR functionalities

- The R-package was designed to easily implement the proposed models on a set of study catchments

- Data requirements are limited to precipitation, temperature and streamflow time series

- The package includes one calibration procedure, testing options and a set of efficiency criteria

- Computation times are limited thanks to the use of fortran routines to run the models

- Outputs include numerical criteria, graphical plots and simulated time series of flows and internal state variables

- The package is flexible enough to include external user-defined models, efficiency criteria or optimization algorithms.
