Runoff given Precipitation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff Volume = Precipitation-Actual Evapotranspiration-Change in Soil Moisture Storage
Q_V = P_mm-E_et-ΔSm
This formula uses 4 Variables

Variables Used

Runoff Volume - (Measured in Cubic Meter) - Runoff Volume is the average amount of water that flows down a particular river, per year, expressed as a volume of water flowing past a given point.
Precipitation - (Measured in Millimeter) - Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations.
Actual Evapotranspiration - (Measured in Cubic Meter per Second) - Actual Evapotranspiration is the quantity of water that is actually removed from a surface due to the processes of evaporation and transpiration.
Change in Soil Moisture Storage - (Measured in Cubic Meter) - Change in Soil Moisture Storage in a catchment.

STEP 1: Convert Input(s) to Base Unit

Precipitation: 35 Millimeter --> 35 Millimeter No Conversion Required
Actual Evapotranspiration: 14 Cubic Meter per Second --> 14 Cubic Meter per Second No Conversion Required
Change in Soil Moisture Storage: 6 Cubic Meter --> 6 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_V = P_mm-E_et-ΔSm --> 35-14-6

Evaluating ... ...

Q_V = 15

STEP 3: Convert Result to Output's Unit

15 Cubic Meter --> No Conversion Required

FINAL ANSWER

15 Cubic Meter <-- Runoff Volume

Runoff given Precipitation Formula

Runoff Volume = Precipitation-Actual Evapotranspiration-Change in Soil Moisture Storage
Q_V = P_mm-E_et-ΔSm

What is Runoff?

Surface runoff is the flow of water occurring on the ground surface when excess rainwater, storm water, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.

Explain the process involved in Runoff?

Runoff occurs when there is more water than the land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. Runoff can come from both natural processes and human activity.

How to Calculate Runoff given Precipitation?

Runoff given Precipitation calculator uses Runoff Volume = Precipitation-Actual Evapotranspiration-Change in Soil Moisture Storage to calculate the Runoff Volume, The Runoff given Precipitation formula is defined as the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate the soil. Runoff Volume is denoted by Q_V symbol.

How to calculate Runoff given Precipitation using this online calculator? To use this online calculator for Runoff given Precipitation, enter Precipitation (P_mm), Actual Evapotranspiration (E_et) & Change in Soil Moisture Storage (ΔSm) and hit the calculate button. Here is how the Runoff given Precipitation calculation can be explained with given input values -> 15 = 0.035-14-6.

FAQ

What is Runoff given Precipitation?

The Runoff given Precipitation formula is defined as the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate the soil and is represented as Q_V = P_mm-E_et-ΔSm or Runoff Volume = Precipitation-Actual Evapotranspiration-Change in Soil Moisture Storage. Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations, Actual Evapotranspiration is the quantity of water that is actually removed from a surface due to the processes of evaporation and transpiration & Change in Soil Moisture Storage in a catchment.

How to calculate Runoff given Precipitation?

The Runoff given Precipitation formula is defined as the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate the soil is calculated using Runoff Volume = Precipitation-Actual Evapotranspiration-Change in Soil Moisture Storage. To calculate Runoff given Precipitation, you need Precipitation (P_mm), Actual Evapotranspiration (E_et) & Change in Soil Moisture Storage (ΔSm). With our tool, you need to enter the respective value for Precipitation, Actual Evapotranspiration & Change in Soil Moisture Storage and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Runoff Volume?

In this formula, Runoff Volume uses Precipitation, Actual Evapotranspiration & Change in Soil Moisture Storage. We can use 1 other way(s) to calculate the same, which is/are as follows -

Runoff Volume = Surface Runoff+Net Ground Water Flowing Outside Catchment
