Fig. 3: Absolute normalized biophysical interaction strengths and associated uncertainty identified with expert knowledge elicitation.

a, Identified interactions and interaction strengths between the selected control variables, ranging from the weakest (~0) to the strongest (1). b, Net originating and receiving interaction strengths for each control variable. Arrow width indicates the magnitude of the interaction strength. Numbers around the circle indicate the sum for both receiving/originating. c, Uncertainty related to assessing the interactions for individual interactions. d, Uncertainty related to assessing the interactions with net originating and receiving interaction strengths. The uncertainty is evaluated on the basis of expert agreement and the number of responses per interaction (Supplementary Table 5.2 gives uncertainty criteria and categorization). BI, biosphere integrity; HF, high-flow season; LF, low-flow season. ‘Not applicable’ refers to the main diagonal in which the same control variable is represented both in the respective column and row. ‘No interaction’ refers to cases for which experts did not identify an interaction existing between these two control variables.
