In this case the second outflow only becomes active if the inflow exceeds the threshold of Qcrit
. In the threshold value approach, the 2nd outlet (e.g. stormwater overflow) is only activated once a critical inflow Qcrit
is exceeded, causing the throttled outflow to back up, reaching the overflow threshold. Since in reality a perfect division of the outflows after reaching the threshold value is usually never achieved, a diversion coefficient can also be specified in order to better represent actual conditions.
It is defined as: [math]\displaystyle{ \mbox{diversion coefficient}= \frac{Q_{in}(Q_{out}=5 \cdot Q_{crit})}{Q_{crit}} }[/math]
