The diurnal component of wet weather flow arises from the day-to-day use of a sanitary system. Often times during rain events flow data has additional flow components present in the time series data, similar to that of combined sanitary systems. The additional wet weather flow components present in sanitary systems are the result of inflow and infiltration. The ability to accurately model and extract the diurnal component of a flow signal is important to accurately study these systems. Most notably, when attempting to analyze and model inflow and infiltration effects within a sanitary system, nuances in long-term infiltration dynamics and rapid peaking during large rain events can be lost or obscured if the diurnal is extracted improperly.
