|Indicates whether design stage discharge curve is achieved in practice. Larger than expected water level fluctuations (i.e. long [[Drainage time|drawdown times]]) may indicate outlet [[clogging]]. Also, measurements may indicate size/intensity of rain events causing [[overflow]] or bypass. | |Indicates whether design stage discharge curve is achieved in practice.
