Throughfall Collectors
There are four throughfall collectors at each site. Throughfall collectors consist of three 6-meter long stainless steel troughs that drain into a large-capacity tipping bucket gage. The gage enclosures are 46.5 cm in diameter and 72 cm tall. The bucket tips at approximately 0.15 liters of water, which represents 0.2 to 0.25 mm of throughfall, depending on the calibration of the individual gage. The collectors were designed by Mike Nullet and Tom Giambelluca, and they are also being used at the Pang Khum Experimental Watershed site in Chiang Mai Province, northern Thailand. |
