Here is how the Total Runoff over Catchment equation looks like.

19.11 = 0.05 + 2 + 16.96 + 100

19.11m³ = 0.05m³/s + 2m³/s + 16.96m³/s + 100mm

19.11 = 0.05 + 2 + 16.96 + 100

Total Runoff over Catchment Solution

Follow our step by step solution on how to calculate Total Runoff over Catchment?

FIRST Step Consider the formula

Q V = S r + I + B + C

Next Step Substitute values of Variables

∴

Q V = 0.05m³/s + 2m³/s + 16.96m³/s + 100mm

Next Step Convert Units

∴

Q V = 0.05m³/s + 2m³/s + 16.96m³/s + 0.1m

Next Step Prepare to Evaluate

∴

Q V = 0.05 + 2 + 16.96 + 0.1

LAST Step Evaluate

∴

Q V = 19.11m³

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

Surface Runoff

Surface Runoff water, from rain, snowmelt, or other sources, that flows over the land surface, and is a major component of the water cycle.

Symbol: S_r

Measurement: Volumetric Flow RateUnit: m³/s

Note: Value should be greater than 0.

Formulas to find Surface Runoff

Interflow

Interflow is the lateral movement of water in the unsaturated zone.

Symbol: I

Measurement: Volumetric Flow RateUnit: m³/s

Note: Value should be greater than 0.

Formulas to find Interflow

Baseflow

Baseflow is the portion of the streamflow that is sustained between precipitation events, fed to streams by delayed pathways.

Symbol: B

Measurement: Volumetric Flow RateUnit: m³/s

Note: Value should be greater than 0.

Formulas to find Baseflow

Channel Precipitation

Channel Precipitation can be defined as the direct rainfall that falls onto surface of stream channel and other waterbodies, including throughfall from vegetation overhanging these water surfaces.

Symbol: C

Measurement: LengthUnit: mm

Note: Value should be greater than 0.
