thumb|Discharge_division_by_Threshold_ConceptHere the second discharge is only activated from a critical inflow Qkrit. In the threshold value model, the 2nd outlet (e.g. RÜ: outlet channel) is only pressurized from a critical inflow Qcrit where the 1st outlet (e.g. RÜ: throttle) backs up to the overflow threshold. Since in reality a perfect division of the outflows after reaching the threshold value is usually not possible, the selectivity for the structure can also be specified for better recording of the actual conditions. thumb| Definition of the parameter Discriminatory Power in Talsim-NG It is defined as: [math]\displaystyle{ \mbox{selectivity }= \frac{Q_{ab}(Q_{zu}=5 \cdot Q_{krit})}{Q_{krit}} }[/math]
