“…This independent dating of halite accumulation confirms that evaporation from the halite nucleus of the Salar de Atacama is much smaller than any previously reported evaporation rates from other playas or salars. Solid symbols represent data from the present study at the Salar de Atacama, and all other symbols represent data compiled by Thorburn et al (1992) from Allison and Barnes (1985), Farrington et al (1989Farrington et al ( , 1990, Jacobson and Jankowski (1989); Malek et al (1990); Talsma (1963); Wind (1955); Woods (1990). The solid circle surrounds values from the Salar de Atacama nucleus, all of which should have evaporation rates of 0 but are shown at 0.001 mm d K1 to conform to the logarithmic scale.…”

“…[5] Estimating vegetation consumption of groundwater using well hydrograph records was proposed by White [1932] and has been used widely in different riparian settings [e.g., Troxell, 1936;Farrington et al, 1990;Gerla, 1992;Rosenberry and Winter, 1997;Loheide et al, 2005;Butler et al, 2007;Lautz, 2008;Loheide, 2008]. The White method provides estimates of groundwater transpiration (ET g ) based on the analysis of diurnal water table fluctuations and an estimate of the specific yield near the water table position.…”

[1] This study utilizes 7 years of continuously monitored groundwater-level data from four sites along the Río Grande riparian corridor in central New Mexico to calculate evapotranspiration from groundwater and assess impacts of understory vegetation removal during a restoration project. Diurnal groundwater fluctuation measurements were used to compare the well-known White method for estimating evapotranspiration from groundwater (ET g ) to colocated measurements of total riparian evapotranspiration (ET) measured using the eddy covariance method. On average, the two methods were linearly correlated and had similar variability, but groundwater hydrograph estimates of ET g tended to be larger than tower ET estimates. Average ET g estimates for two wells at one site ranged from 91.45% to 164.77% of measured tower ET estimates, but were also shown to range from 57.35% to 254.34% at another site. Comparisons between the methods improved with deeper water tables, reduced groundwater and river connectivity, and where soil profiles were dominated by coarse-sized particles. Using a range of texturebased estimates of specific yield (S y ) with water table position improves the field application of the White method. River-induced fluctuations in groundwater increased the variability of ET g measurements. Removal of understory vegetation at one site resulted in a small but significant reduction in diel groundwater fluctuation amplitude of 19-21%. Caution is required when understory vegetation removal is used as a means to decrease overall riparian ET. Diel groundwater fluctuation amplitudes can be useful in gauging the hydrological effects of vegetation removal. Riparian groundwater hydrographs are critical to investigating the hydrologic connectivity between river and shallow groundwater, the temporal patterns of vegetative consumption, and monitoring changes to the vegetation community.

“…The saw-tooth pattern seen in the water table fluctuations of Well 1 (located at position 1 in Fig. 2) was produced by both ET and ground water inflow (Farrington et al, 1990). During the day, ET removed water and the water table fell.…”
