# The average annual rainfall in this area is 745 mm / year, and the moisture coefficient is 1.15. As a result of deforestation

The average annual rainfall in this area is 745 mm / year, and the moisture coefficient is 1.15. As a result of deforestation, evaporation from this area increased by 50%. Calculate the new moisture factor.

Evaporation is the amount of moisture that can evaporate from a surface at a specific temperature.
The moisture coefficient is the ratio of the annual precipitation to the annual evaporation. It is determined by the formula:
K = O: And, hence I = O: K
1) Find the volatility in a given area:
I = O: K = 745 mm / year: 1.15 = 648 mm / year
2) Due to deforestation, evaporation increased by 50% and is equal to:
648 mm / year + 648 mm / year: 2 = 972 mm / year
3) Let’s define a new moisture factor:
K = O: I = 745 mm / year: 972 mm / year = 0.77
Answer: The new moisture factor is 0.77.
