Regional-scale coverage of – flux data are generally lacking, although there are local studies that have attempted to quantify these fluxes (; ). For regional-scale modelling, local-scale data can be useful for defining the variability in surface water – groundwater connections across the subregion and putting some upper and lower bounds on the groundwater contribution to streamflow (expressed as a proportion of total streamflow, or ; see also ). In the salinity assessment of the Hunter River basin, it was concluded that ‘the detailed interaction between groundwater and surface water in many parts of the Hunter River catchment still requires further research’.
No observed that specifically represent surface water – groundwater interactions have been used as inputs into the hydrological modelling of the because this is a variable calculated by the model, nor have they been used to constrain model results. Instead a range of common approaches to estimating the groundwater contribution to streamflow are used to determine possible ranges, including extrapolation from local-scale information reported in a mine environmental impact statement (EIS; Section 220.127.116.11).
