Runoff given Precipitation Solution

Follow our step by step solution on how to calculate Runoff given Precipitation?

FIRST Step Consider the formula

Q V = P mm - E et - ΔSm

Next Step Substitute values of Variables

∴

Q V = 35mm - 14m³/s - 6m³

Next Step Prepare to Evaluate

∴

Q V = 35 - 14 - 6

LAST Step Evaluate

∴

Q V = 15m³

Variables

Runoff Volume

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.

Symbol: Q_V

Measurement: VolumeUnit: m³

Note: Value should be greater than 0.

Formulas to find Runoff Volume

Precipitation

Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations.

Note: Value should be greater than 0.

Formulas to find Precipitation

Actual Evapotranspiration

Actual Evapotranspiration is the quantity of water that is actually removed from a surface due to the processes of evaporation and transpiration.

Symbol: E_et

Measurement: Volumetric Flow RateUnit: m³/s

Note: Value should be greater than 0.

Formulas to find Actual Evapotranspiration

Change in Soil Moisture Storage

Change in Soil Moisture Storage in a catchment.

Symbol: ΔSm

Measurement: VolumeUnit: m³

Note: Value should be greater than 0.

How to Evaluate Runoff given Precipitation?

Runoff given Precipitation evaluator uses Runoff Volume = Precipitation-Actual Evapotranspiration-Change in Soil Moisture Storage to evaluate 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 evaluate Runoff given Precipitation using this online evaluator? To use this online evaluator for Runoff given Precipitation, enter Precipitation (P_mm), Actual Evapotranspiration (E_et) & Change in Soil Moisture Storage (ΔSm) and hit the calculate button.

FAQs on Runoff given Precipitation

What is the formula to find Runoff given Precipitation?

The formula of Runoff given Precipitation is expressed as Runoff Volume = Precipitation-Actual Evapotranspiration-Change in Soil Moisture Storage. Here is an example- 15 = 0.035-14-6.

How to calculate Runoff given Precipitation?

With Precipitation (P_mm), Actual Evapotranspiration (E_et) & Change in Soil Moisture Storage (ΔSm) we can find Runoff given Precipitation using the formula - Runoff Volume = Precipitation-Actual Evapotranspiration-Change in Soil Moisture Storage.

What are the other ways to Calculate Runoff Volume?

Here are the different ways to Calculate Runoff Volume-

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

Can the Runoff given Precipitation be negative?

No, the Runoff given Precipitation, measured in Volume cannot be negative.

Which unit is used to measure Runoff given Precipitation?

Runoff given Precipitation is usually measured using the Cubic Meter[m³] for Volume. Cubic Centimeter[m³], Cubic Millimeter[m³], Liter[m³] are the few other units in which Runoff given Precipitation can be measured.
