“…This is sometimes termed the equilibrium evaporation slope, which applies to evaporation of local precipitation [see Gat and Bowser, 1991], but is distinguished from nonequilibrium evaporation slopes, which describe evaporation of allochthonous water sources, i.e., waters introduced by long-distance river transport, regional groundwater flow, or artificial diversions. Local evaporation lines (LELs) have been widely reported from field studies of water bodies [e.g., Dinçer, 1968;Zuber, 1983;Gibson, 2002;Gibson et al, 1993Gibson et al, , 2005 and soil water [e.g., Barnes and Allison, 1988;. In general, soil water LELs have been reported as having lower slopes than open water LELs, attributed to vapor transport through the stagnant, diffusiondominated soil matrix.…”
