Rain Gauges are located to collect rain over a specified area. The rain falls through a defined aperture and into an inner can. The contents are then measured, normally once a day, by pouring into a measuring jar. Universally used by professional and amateur meteorologists, these models are also ideal for educational, industrial and other applications.
Rainfall is one of the most important watershed variables. Rainfall can significantly affect the amount of runoff into streams. Rainfall rate and quantity interact with many other factors to influence erosion, vegetative cover, ground water recharge, stream water chemistry and runoff of nonpoint source pollution into stream.
