CMBEAR - Chloride Mass Balance Estimator of Australian Recharge

CMBEAR (the Chloride Mass Balance Estimator of Australian Recharge) is a Jupyter notebook that, as the name suggests, provides a simple and highly reproducible approach to estimate groundwater recharge using the Chloride Mass Balance method for Australian groundwater data. The notebook is set up to estimate recharge using Australian data and can be used in other regions if a gridded chloride deposition map is provided.

The notebook was written by Dylan Irvine (Charles Darwin University). The approach uses maps of Chloride deposition from Davies and Crosbie (2018, Journal of Hydrology), maps of long-term average rainfall (1916-2015) calculated from data from the Bureau of Meteorology, and user-supplied groundwater chloride concentrations (with associated latitude/longitude information) to apply the chloride mass balance method.

NOTE: The Jupyter notebook is associated with a methods note at Groundwater. If you use CMBEAR, could you please cite the Groundwater paper:

The notebooks are simple to apply, with the main input being a simple spreadsheet.

The files contained here are:
- CMBEAR.zip, which contains all of the files required to run the tool.
- NT_data_prep.zip, which contains the data files to prepare an input file to estimate recharge in the Northern Territory of Australia
- Vic_WT_map_upload.zip, which contains a description of how input files were prepared to assess groundwater recharge using a gridded water table salinity map.
