The analysis of surface water – groundwater interactions is an essential part of the Clarence-Moreton Bioregional Assessment (the Assessment). Links between surface water and groundwater can be inferred from a range of different approaches (e.g. Martinez et al., 2015; Duvert et al., 2015); ideally, where available, multiple lines of evidence are integrated, which include:
- geological evidence (e.g. geomorphology of river valleys, sediment composition of aquifers or presence of geological structures that may induce connectivity to the surface)
- groundwater levels and streambed levels
- groundwater and surface water chemistry
- climate data
- wetland mapping
- remote sensing
- digital elevation models (DEMs)
- isotopic data
- streamflow time series data
In the Assessment, the interactions between surface water and groundwater can be broadly grouped into two categories:
- stream–aquifer interactions
- aquifer–wetland interactions.
The analysis of surface water – groundwater interactions is an ongoing process, and it will be described in more detail during later stages of the Assessment and included in subsequent products (e.g. companion product 2.3 for the Clarence-Moreton bioregion (Raiber et al., 2016)).
