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) |
