Gully erosion: Also called ephemeral gully erosion, this process occurs when water flows in narrow channels during or immediately after heavy rains or melting snow. A gully is sufficiently deep that it would not be routinely destroyed by tillage operations whereas rill erosion is smoothed by ordinary farm tillage. The narrow channels, or gullies, may be of considerable depth , ranging from 1 to 2 feet to as much as 75 to 100 feet. Gully erosion is not accounted for in the universal soil loss equation. In a few states gully erosion is substantial, but in most areas more soil is lost through sheet erosion and rill erosion.
Gust: A brief sudden increase in wind speed. Generally the duration is less than 20 seconds and the fluctuation greater than 10 mph.
Gust Front: The leading edge of the downdraft from a thunderstorm.
Guttation: The loss of water in liquid form from the uninjured leaf or stem of the plant, principally through water stomata.
