HydroBudget – Groundwater recharge model in R

It was developed as an accessible and computationally affordable model to simulate GWR over large areas (thousands of km2, regional-scale watersheds) and for long time periods (decades), in cold and humid climates. The model is coded in R and was developed at UQAM by the team of Pr Marie Larocque’s research Chair (Water and land conservation) as part of a project funded by the Quebec Ministry of the Environment (Ministère de l’Environnement et de la Lutte contre les changements climatiques - MELCC).

Results of GWR simulation over southern Quebec (Canada) with HB are presented in Dubois et al. (2021). Le model script is provided with an application example for the Petite du Chene River in southern Quebec and a User-guide. As of July 2023, the further development of the HydroBudget model will be included in the rechaRge package.
