This formula uses 7 Variables

Variables Used

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 of Return Flow - (Measured in Cubic Meter per Second) - Volume of Return Flow from irrigation, domestic water supply and industrial use.
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

Observed Flow Volume: 50 Cubic Meter per Second --> 50 Cubic Meter per Second No Conversion Required
Volume of Return Flow: 10 Cubic Meter per Second --> 10 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

R_N = (R_o-V_r)+V_d+E_M+F_x+ΔSv --> (50-10)+12+2+100+20

Evaluating ... ...

R_N = 174

STEP 3: Convert Result to Output's Unit

174 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

174 Cubic Meter per Second <-- Natural Flow Volume

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.

How to Calculate Natural Flow Volume?

Natural Flow Volume calculator uses Natural Flow Volume = (Observed Flow Volume-Volume of Return Flow)+Volume Diverted Out of Stream+Net Evaporation Losses+Net Export of Water from Basin+Change in Storage Volumes to calculate the Natural Flow Volume, The Natural Flow Volume formula is defined as the quantity of water that would have flowed in a river past a particular point in a particular period but for the effect during that period of diversions to or from, and impoundments on, the river upstream of that point. Natural Flow Volume is denoted by R_N symbol.

How to calculate Natural Flow Volume using this online calculator? To use this online calculator for Natural Flow Volume, enter Observed Flow Volume (R_o), Volume of Return Flow (V_r), Volume Diverted Out of Stream (V_d), Net Evaporation Losses (E_M), Net Export of Water from Basin (F_x) & Change in Storage Volumes (ΔSv) and hit the calculate button. Here is how the Natural Flow Volume calculation can be explained with given input values -> 174 = (50-10)+12+2+100+20.
