15.4.1 Sap Flux Measurement The method presented is one of the most common systems used to measure sap flux in trees and has gained widespread acceptance in studies of water use at the tree level (e.g Meinzer et al., 2005; Giambelluca et al. 2003). Thermal dissipation probes were originally developed by Granier (1985) and used heat as a tracer for the detection of water movement in the sapwood of a tree. 30
