Although some examples are interspersed throughout this submethodology, it is recommended that M08 be read in conjunction with its application in product 2.7 (receptor impact modelling) for each or . The structure in product 2.7 closely follows the methodology outlined in M08. Table 11 shows the recommended content for product 2.7. It identifies those (or ) that may experience some hydrological change and those that are to do so. For those that do, product 2.7 provides a summary of the landscape class (or landscape group) and how it works, details the qualitative mathematical modelling expert workshop and sign-directed graph output for that landscape class, describes the choice of and selected, summarises the elicitation scenarios presented to experts, and concludes with a description of the that is constructed and any interpretations that may be made around it.

HRV = hydrological response variable, RIV = receptor impact variable
The receptor impact modelling methodology (this product) and its implementation was affected by design choices that have been made within BA. Some of these broader choices are described in companion submethodology M10 (as listed in Table 1) for analysing impacts and (Henderson et al., 2018). Table 12 summarises some of the assumptions made for the receptor impact modelling, the implications of those assumptions for the results, and how those implications are acknowledged through the BA products.

BA = bioregional assessment, HRV = hydrological response variable, RIM = receptor impact model, RIV = receptor impact variable
Product 2.7 (receptor impact modelling) does not cover results for the prediction of receptor impact variables. These results are addressed as part of product 3-4 (impact and risk analysis). Companion submethodology M10 (as listed in Table 1) for analysing impacts and risks (Henderson et al., 2018) describes some of the additional underlying methodology for these results, and in particular the choice of summary and aggregation of predictions to landscape classes and . These results for landscape classes and assets are derived by applying the methodology described in Section 8.1 and Section 8.2.
