Tamarix spp. (Saltcedar) is a facultative phreatophyte that can tolerate drought when groundwater is not accessed. In addition to deep water uptake, hydraulic redistribution (HR) is another factor contributing to the drought tolerance of Tamarix spp. In this study, data on soil volumetric moisture content (θ), lateral root sap flow, and relevant climate variables were used to investigate the ...Kipple, F.P., 1977, The hydrologic history of the San Carlos Reservoir, Arizona, 1929-71, with particular reference to evapotranspiration and sedimentation - Gila River Phreatophyte Project: U.S. Geological Survey Professional Paper 655-N, p. N1-N40.The three models we used to simulate transpiration at hourly and daily scales are the modified Jarvis-Stewart model (Section 3.1 ), the simplified process-based model (Section 3.2 ), and the artificial neural network model (Section 3.3 ). The methods of model calibration and validation are presented in Section 3.4.Subject matter experts then reviewed the combination of ecoregion location and dominant species names against published lists of phreatophytes to determine (1) if the dominant species was a listed phreatophyte, and if so, (2) was likely to be phreatophytic in that ecoregion or likely to rely on surface water, precipitation, or other non ...

Alhagi sparsifolia Shap., a dominant perennial phreatophyte grown at the southern rim of the Taklimakan Desert, has an important influence on wind prevention and sand fixation in the local ecosystem. A. sparsifolia is a leguminous plant and is an economically important species for local livestock because of its high protein …phreatophyte control offers the possibility of water sal­ vage. The hydrologic regime of the flood plain of a major river is a complex system of which evapotran­ spiration is only one part. Thus, a change in evapo­ transpiration changes ground-water levels, relations of surface water and ground water, and soil-moisture ...Phreatophyte consumption of groundwater has also been estimated using the water balance residual from field studies in which the other components of the water balance have been calculated from monitoring data [Weeks and Sorey, 1973]. However, the large uncertainty regarding subsurface inflows and outflows, among other aspects of the water ...Phreatophyte. a plant with an extremely deep root system that uses groundwater as its source of moisture. A classical example is the date palm ( Phoenix dactylifera ), which grows on oases in the Sahara and the Arabian Peninsula. (An ancient Arabic proverb says that the date palm has its head in fire and its feet in water.)Populus euphratica Oliv. is a widespread phreatophytic tree species that forms riparian forests in (hyper-)arid regions of Central Asia. Its recruitment strongly relies on vegetative propagation from 'root suckers' that emerge from underground root spacers. The water transport through the spacers, a …

The term “phreatophyte” derives from the classical Greek word “φρεαρ” (well, cistern). Daly ( 1917) used the term “phreatic water” as a synonym for groundwater for all water in the zone of water saturation. Meinzer ( 1923) coined the term “phreatophyte” for “a ... In addition, multiscenario estimations showed nonlinear responses of phreatophyte ET to the rate of GWL decrease (RGWD); that is, as the RGWD accelerated, plant adaptation showed three different ... ….

Phreatophytes are plants that depend for their water supply upon ground water that lies within reach of their roots. Although not confined to the arid regions of the Western United States, their occurrence there is more common, more spectacular, and, because of their effect on water supply, more important than it is in humid and subhumid regions.tials than plants grow ing in fine-tex tured soils.

Groundwater evapotranspiration (ETg) from phreatophyte vegetation is the primary component of natural groundwater discharge within the Humboldt River Basin. This report summarizes previous study estimates of ETg, and details methods and results of updated groundwater discharge areas, ETg rates, and ETg volume estimates developed in this study.I intend to utilize the following posts to share some of my highlights, lowlights, and lessons learned about and aboard my 1978 Yamaha 25 sailboat.

The foliage of small pinnately compound blue-green leaves is absent most of the year in response to dryness. However, photosynthesis is performed by the smooth, spiny, blue-green branches and twigs. In spring, masses of ...

claiming full exemption from federal tax withholding A phreatophyte is a deep-rooted plant that obtains a significant portion of the water that it needs from the phreatic zone or the capillary fringe above the phreatic zone. Phreatophytes are plants that are supplied with surface water and often have their roots constantly in touch with moisture. A phreatophyte is one that absorbs its water from a constant source on the ground.anisohydric phreatophyte in arid and semiarid re gions see ms to be a r isky option, which can only be. overc ome by the re silience capacity of the plants (Hultine et al., 2020).
