4 cards from this section. Quick, good the night before a test.
What does the Blaney-Criddle method estimate?
Think about what factors influence water loss.
Which method adjusts for seasonal variations?
Consider which method we've discussed that relates to temperature.
Which method is suited for estimating ET when climatic data is scarce?
Think about which methods have less data requirement.
True or False: The Thornthwaite method is only applicable in humid climates.
Consider how adaptable this method is.
A farmer has recorded a temperature of 30°C and an average of 12 daylight hours using the Blaney-Criddle method. Calculate the potential evapotranspiration if K is set at 0.25.
Plug in the temperature and daylight values into the formula.
Using the Penman-Monteith method, if you have the net radiation as 300 W/m², wind speed at 2 m/s, and vapor pressure deficit as 2 kPa, estimate the potential evapotranspiration.
Remember how wind speed and radiation influence the ET!
