Actual Evapotranspiration given Runoff Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
Precipitation - (Measured in Millimeter) - Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations.
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.
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
Runoff Volume: 19.5 Cubic Meter --> 19.5 Cubic Meter 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

E_et = P_mm-Q_V-ΔSm --> 35-19.5-6

Evaluating ... ...

E_et = 9.5

STEP 3: Convert Result to Output's Unit

9.5 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

9.5 Cubic Meter per Second <-- Actual Evapotranspiration

(Calculation completed in 00.004 seconds)

Change in Soil Moisture Storage given Runoff

Go Change in Soil Moisture Storage = Precipitation-Runoff Volume-Actual Evapotranspiration

Actual Evapotranspiration given Runoff

Go Actual Evapotranspiration = Precipitation-Runoff Volume-Change in Soil Moisture Storage

Runoff given Precipitation

Go Runoff Volume = Precipitation-Actual Evapotranspiration-Change in Soil Moisture Storage

Net Groundwater Outflow given Runoff

Go Net Ground Water Flowing Outside Catchment = Runoff Volume-Surface Runoff

Surface Runoff using Runoff

Go Surface Runoff = Runoff Volume-Net Ground Water Flowing Outside Catchment

Equation for Runoff

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

Actual Evapotranspiration given Runoff Formula

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