Mass balance term	Description
Terms related to inflow
(01) Watershed Inflow	Inflow from watershed(s) assigned to the device
(02) Device Inflow	Inflow from upstream devices
(09) Total Inflow	Total Inflow = (01) + (02)
Terms related to sedimentation, infiltration, and filtration
(03) Infiltration	Outflow passing through bottom/sides of device
(05) Filtration Removal	Pollutant removed through filtration through media
(04) Exfiltration	Exfiltration = (03) - (05)
(08) Sedimentation + Decay	Pollutant removed via sedimentation and/or decay
(13) Total Trapped	Total Trapped = (05) + (08)
Terms related to outflow
(06) Normal Outflow	Outflow passing thru the primary outlet
(07) Spillway Outflow	Outflow passing thru the secondary outlet
(10) Surface Outflow	Surface Outflow = (06) + (07)
(11) Groundwater Outflow	Groundwater Outflow = (03) - (05) = (04)
(12) Total Outflow	Total Outflow = (10) + (11)
Terms related to mass balance and error
(14) Storage Increase	Increase in storage volume (or mass) from one time step (or event) to the next
(15) Mass Balance Check	Error term in mass-balance equations. Error = (12) - (09)
