Overflow - hourly listing of all overflows at each structure
Storms - summary data for each storm during simulation
Capture - summary data of treated flow at each structure for each storm
Details - complete hourly output for selected structure(s) [depends on setting of DETAILS in STRUCTURE table]
Formulas for computation of inflow, capture, and percent capture are presented below:
Capture volume (flow-based) = (totcap – dwph × (hflow – hrain)) ÷ ny
Capture volume (time-based) = totcap ÷ ny
Percent capture = 100 × capvol ÷ (capvol + annvol)
Upstream DWF = (dwph – localdwph) × hrain ÷ ny
Upstream Runoff = (totusflow – (dwph – localdwph) × hflow) ÷ ny
Local DWF = localdwph × hrain ÷ ny
Local Runoff = (capvol + annvol – totusflow – localdwph × hflow) ÷ ny
where:
totcap = volume treated during hours model ran (MG)
dwph = dry weather flow per hour from upstream and local areas (MG)
hflow = total time the model computed flows for (h)
hrain = total duration of storm events including dry hours during storms (h)
ny = number of years the model ran
annvol = overflow volume (MG)
localdwph = dry weather flow per hour from local sewershed only (MG)
capvol = capture volume (as defined above)
totusflow = total inflow to node from upstream structures (MG)
