Abstract: The present invention relates to a system (S) and a process for determining the water equivalent content of a snowpack (Snow Water Equivalent—SWE)

Abstract: A device (12) for measuring the water content of the ground, vegetation and snow, comprises: at least one first module (20) adapted to measure a flow of cosmic rays incident to the ground; at least one second module (40) adapted to measure an ambient neutron flow; and a control unit (60) connected to said at least one first module (20) and said at least one second module (40). The control unit (60) is adapted to process the measurements of said at least one first module (20) and said at least one second module (40) to determine the measurement of the water content.

Abstract: A device for measuring water content of the ground, vegetation and snow includes an ambient neutron detector to measure ambient neutron flow, having first and second sheets made at least partially with a scintillator. A light meter measures light conveyed by a light guide interposed between the first and second sheets. The ambient neutron detector transforms interaction with particle(s) into an electric charge. A programmable control unit connects to the ambient neutron detector, and includes an integrating circuit transforming the electric charge produced by interaction with the particle(s) into a signal. The control unit processes the signal to discriminate a signal generated by ambient neutron, incident cosmic rays and/or background noise, and measures ambient neutron flow, incident cosmic rays, and/or background noise. The measurement of the water content is obtained from measurement of normalized ambient neutron flow with respect to measurement of cosmic rays flow incident to the ground.
