Prediction of receptor impact variables

Figure 3 in Section summarises the receptor impact modelling workflow, starting from the identification of the landscape classes that occur within the zone of potential hydrological change for the Hunter subregion and that may be impacted through to the prediction of receptor impact variables at assessment units. This product concludes with the construction and interpretation of the receptor impact models, and the relationship between the receptor impact variable and one or more hydrological response variables used in the model. While this allows some assessment of the sensitivity of the response to the hydrological response variables, it needs to be stressed that these should not be interpreted as risk predictions. Receptor impact variable prediction at assessment units occurs in the impact and risk product (companion product 3-4 for the Hunter subregion (Herron et al., 2018)), where the hydrological response variables are propagated through the receptor impact models to produce a range or distribution of the predicted receptor impact variable response at different time points and for the two futures considered in BAs. These distributions reflect the uncertainty in the hydrological response variables, the uncertainty the experts have in the potential ecosystem response to those hydrological response variables, and the spatial heterogeneity across the landscape class.
