Actual Evapotranspiration Solution

STEP 0: Pre-Calculation Summary
Formula Used
Actual Evapotranspiration = Precipitation-Change in Moisture Storage-Surface Runoff-Subsurface Outflow
Eact = P-ΔS-Sr-Go
This formula uses 5 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 Meter) - Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations.
Change in Moisture Storage - (Measured in Meter) - Change in Moisture Storage is the total amount of water that is stored within the specified reservoir or catchment area.
Surface Runoff - (Measured in Cubic Meter per Second) - Surface Runoff water, from rain, snowmelt, or other sources, that flows over the land surface, and is a major component of the water cycle.
Subsurface Outflow - (Measured in Cubic Meter per Second) - Subsurface Outflow is the flow of water beneath earth's surface as part of the water cycle.
STEP 1: Convert Input(s) to Base Unit
Precipitation: 0.3 Meter --> 0.3 Meter No Conversion Required
Change in Moisture Storage: 0.02 Meter --> 0.02 Meter No Conversion Required
Surface Runoff: 0.05 Cubic Meter per Second --> 0.05 Cubic Meter per Second No Conversion Required
Subsurface Outflow: 0.07 Cubic Meter per Second --> 0.07 Cubic Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Eact = P-ΔS-Sr-Go --> 0.3-0.02-0.05-0.07
Evaluating ... ...
Eact = 0.16
STEP 3: Convert Result to Output's Unit
0.16 Cubic Meter per Second --> No Conversion Required
FINAL ANSWER
0.16 Cubic Meter per Second <-- Actual Evapotranspiration
(Calculation completed in 00.020 seconds)

7 Evapotranspiration Calculators

Runoff given Change in Moisture Storage
Go Surface Runoff = -(Change in Moisture Storage-Precipitation+Subsurface Outflow+Actual Evapotranspiration)
Subsurface Outflow given Change in Moisture Storage
Go Subsurface Outflow = Precipitation-Change in Moisture Storage-Surface Runoff-Actual Evapotranspiration
Precipitation given Change in Moisture Storage
Go Precipitation = Change in Moisture Storage+Surface Runoff+Subsurface Outflow+Actual Evapotranspiration
Change in Moisture Storage
Go Change in Moisture Storage = Precipitation-Surface Runoff-Subsurface Outflow-Actual Evapotranspiration
Actual Evapotranspiration
Go Actual Evapotranspiration = Precipitation-Change in Moisture Storage-Surface Runoff-Subsurface Outflow
Aridity Index
Go Aridity Index = ((Daily Potential Evapotranspiration-Actual Evapotranspiration)/Daily Potential Evapotranspiration)*100
Actual Evapotranspiration given Aridity Index
Go Actual Evapotranspiration = Daily Potential Evapotranspiration-(Aridity Index*Daily Potential Evapotranspiration/100)

Actual Evapotranspiration Formula

Actual Evapotranspiration = Precipitation-Change in Moisture Storage-Surface Runoff-Subsurface Outflow
Eact = P-ΔS-Sr-Go

What Factors Affect Evapotranspiration?

Factors that affect Evapotranspiration include the plant's growth stage or level of maturity, percentage of soil cover, solar radiation, humidity, temperature, and wind.

How to Calculate Actual Evapotranspiration?
