The limitation of water sources in most places all over the
world, especially in arid and semi-arid lands is an
important Issue for those who live in these areas. Many
governments have dedicated their efforts toward finding
new water resources to obtain water.
Fog and cap clouds harvesting are one of the
candidate methods to produce pure water. Many countries
including Chile, Peru, Ecuador, Canada, Namibia and
Nepal Have yet invested on fog harvesting. On the other
hand, no significant calculation studies have been yet
carried out on quantifying fog harvesting.
In this work, we examined the Physical and dynamic
relationship between cloud physics and atmosphere
humidity; factors such as distribution of particle amounts,
collection efficiency, water including base cloud and
vapour flux were all considered. We also presented a new
method to estimate fog harvesting, based on fractal theory
and concerning the characteristics of collecting devices.
Finally, we successfully evaluated the theories for fractal
dimension of particle distribution, using the real data of
fog harvesting. The incremental fractal dimension
reliability was found to be 83% acceptable.
