Rain
(Precipitation)
As captured at White Pine Lake in Logan Canyon, Utah, this video portrays rain precipitating out of the sky at a fairly intense rate onto the lake itself and its surrounding area. Precipitation is formed when the air in clouds becomes saturated with water vapor, and condensation causes water droplets to form and fall through the cloud. Large water droplets falling from the sky are classified as "rain" while small water droplets falling is classified as a "drizzle".
Saturation Excess Overland Flow
As captured at White Pine Lake in Logan Canyon, Utah, this picture was taken after 8 hours of rain had already been falling since the early morning of September 4, 2023. Saturation Excess Overland Flow occurs when the soil of an area becomes completely saturated with water and cannot hold anymore; excess water then starts flowing from high to low points of the topography. In this picture, water on higher areas can be seen forming small water channels that lead to lower puddled areas along the local topography.
Base Flow
The picture to the left was taken on a sunny day in late August last year on the Logan River while wading through the stream. It depicts base flow of the river in this specific channel, where the level of flow is dictated by groundwater inflow and not runoff or storm precipitation.
Snow (Precipitation)
The video to the left was recorded at the bottom of Old Main Hill this February of 2024. It depicts frozen water vapor which has formed ice crystals falling as precipitation, aka snow, and the shadows snow creates under a lamp post.
Condensation
This picture was also taken at the bottom of Old Main Hill at USU in February 2024 on a night when no snow was falling. It depicts a cold lamp post which has begun forming condensation as the warmer humid air around it is cooled as it touches the lamp post. This cooling of the warmer humid air causes the water vapor in the air to reach its dewpoint, and water droplets are released from the saturated air onto the lamp post. The water droplets can be seen coalescing on the lamp post, initiating movement as gravity pushes coalesced water droplets downward.
