HydroBudget – Groundwater recharge model in R

HydroBudget (HB) is a spatially distributed groundwater recharge (GWR) model that computes a superficial water budget on grid cells with outputs aggregated into monthly time steps. 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.

HydroBudget（简称HB）是一款空间分布式地下水补给（groundwater recharge, GWR）模型，可在网格单元上计算表层水收支，并将输出结果整合为月度时间步长。该模型旨在开发为一款易用且计算成本低廉的工具，用于在寒冷湿润气候下，对大面积区域（数千平方千米的区域尺度流域）以及长时段（数十年）的地下水补给过程进行模拟。此模型采用R语言编写，由加拿大魁北克大学蒙特利尔分校（UQAM）Marie Larocque教授（水资源与土地保护研究讲席）团队开发，项目由魁北克环境与气候变化应对部（Ministère de l’Environnement et de la Lutte contre les changements climatiques, 简称MELCC）资助。Dubois等人（2021年）展示了利用HB对加拿大魁北克南部地区开展地下水补给模拟的研究结果。模型脚本附带了魁北克南部小舍讷河（Petite du Chene River）的应用示例与用户指南。截至2023年7月，HydroBudget模型的后续开发工作将整合至rechaRge软件包中。更多相关信息可访问：https://www.epfl.ch/labs/lch/research/water-and-groundwater-management/recharge-an-r-package-for-integrated-groundwater-recharge-modelling-in-r/ 此外，代码的开发进度可通过以下仓库追踪：https://github.com/gwrecharge
