Abstract:
Nucl6onic Snow Gauge has been used for the first time in India for measurement of water equivalent of snow cover at a snow course in BEAS Basin. The gauge consists of CS-137 sources, NaI(Tl) detectors and gamma ray counting instruments. The gauge has an RS-232 interface for data transmission to Central Station via Vhf link and remote control facility. The paper disCusses experimental setup of Nucleonic Snow Gauge and presents formula for computation of water equivalent from gamma ray counts. Paper also discusses integration of Nucleonic Snow Gauge with Automatic Weather Stations as a water equivalent sensor. A comparison of Nucleonic Snow Gauge data with limited manual measurements has been made.
