Direct Surface Runoff given Total Precipitation Formula Elements

Variables

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.

Symbol: Q

Measurement: VolumeUnit: m³

Note: Value should be greater than 0.

Formulas to find Direct Surface Runoff

Total Precipitation

Total Precipitation is the sum of rainfall and the assumed water equivalent of snowfall for a given year.

Symbol: P_T

Measurement: VolumeUnit: m³

Note: Value should be greater than 0.

Formulas to find Total Precipitation

Initial Abstraction

Initial Abstraction is a parameter that accounts for all losses prior to runoff and consists mainly of interception, infiltration, evaporation, and surface depression storage.

Symbol: I_a

Measurement: VolumeUnit: m³

Note: Value can be positive or negative.

Formulas to find Initial Abstraction

Cumulative Infiltration

The cumulative infiltration excluding initial abstraction is total amount of water that soil strata are able to absorb from rainfall or irrigation in a given time.

Symbol: F

Measurement: VolumeUnit: m³

Note: Value should be greater than 0.

Formulas to find Cumulative Infiltration

Other formulas in Basic Theory category

Go Water Balance Equation for Rainfall

P T = I a + F + Q

Go Initial Abstraction

I a = P T - F - Q

Go Actual Infiltration

F = S \cdot (\frac{Q}{P T - I a})

Go Cumulative Infiltration given Total Precipitation

F = P T - I a - Q
