Volume of Return Flow Solution

STEP 0: Pre-Calculation Summary
Formula Used
Volume of Return Flow = -Natural Flow Volume+Observed Flow Volume+Volume Diverted Out of Stream+Net Evaporation Losses+Net Export of Water from Basin+Change in Storage Volumes
Vr = -RN+Ro+Vd+EM+Fx+ΔSv
This formula uses 7 Variables
Variables Used
Volume of Return Flow - (Measured in Cubic Meter per Second) - Volume of Return Flow from irrigation, domestic water supply and industrial use.
Natural Flow Volume - (Measured in Cubic Meter per Second) - Natural Flow Volume is the quantity of water that would have flowed in a river past a particular point in a particular period.
Observed Flow Volume - (Measured in Cubic Meter per Second) - Observed Flow Volume is the recorded the quantity of water that would have flowed in a river past a particular point in a particular period.
Volume Diverted Out of Stream - (Measured in Cubic Meter per Second) - Volume Diverted Out of Stream for irrigation, domestic water supply and industrial use.
Net Evaporation Losses - Net Evaporation Losses from Reservoirs on the Stream is the loss of stored volatile liquid component or mixture by evaporation by temperature, pressure, and vapor-recovery systems.
Net Export of Water from Basin - Net Export of Water from Basin, any area of land where precipitation collects and drains off into a common outlet.
Change in Storage Volumes - Change in Storage Volumes of water storage bodies on the stream is the difference of water incoming and outgoing.
STEP 1: Convert Input(s) to Base Unit
Natural Flow Volume: 174 Cubic Meter per Second --> 174 Cubic Meter per Second No Conversion Required
Observed Flow Volume: 50 Cubic Meter per Second --> 50 Cubic Meter per Second No Conversion Required
Volume Diverted Out of Stream: 12 Cubic Meter per Second --> 12 Cubic Meter per Second No Conversion Required
Net Evaporation Losses: 2 --> No Conversion Required
Net Export of Water from Basin: 100 --> No Conversion Required
Change in Storage Volumes: 20 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Vr = -RN+Ro+Vd+EM+Fx+ΔSv --> -174+50+12+2+100+20
Evaluating ... ...
Vr = 10
STEP 3: Convert Result to Output's Unit
10 Cubic Meter per Second --> No Conversion Required
FINAL ANSWER
10 Cubic Meter per Second <-- Volume of Return Flow
(Calculation completed in 00.004 seconds)

What is Direct Surface Runoff?

Direct Surface Runoff is the rain or meltwater that runs off during the rain or melt event as overland flow or in the vegetation cover above frozen soil. The meltwater and the rain falling onto snow or on frozen ground reach a stream along different pathways.
