Diagram representing the event analysis in the connectivity module: events are defined as sections of the hydrograph exceeding the connectivity threshold H0 as derived from the computation of a minimum surface by numerical modelling of a water surface drawdown; in order to account for retention leading to levelling of comparably small peaks in the hydrograph, events are counted only if exceeding a critical water surface elevation HC. Event duration is denoted by TEi, intervals between events by TIi.
