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.61 EXERCISE 16 Questions 1.

Initially, White [1932] assumed that (1) declines in groundwater levels were only caused by the evapotrans-piration by plants; (2) evapotranspiration by phreatophyte vegetation was negligible from midnight to 4A phreatophyte is a deep- rooted plant that obtains a significant portion of the water that it needs from the phreatic zone (zone of saturation) 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. Riparian vegetation in the Upper Brazos was dominated by obligate and facultative phreatophytes, such as mesquite, baccharis, cottonwood, willow, elm, hackberry, and sumac (Blackburn et al. 1982). Nonnative saltcedar has increasingly affected riparian areas in the Upper Brazos ( Busby and Schuster 1971 , Blackburn et al. 1982 ).Phreatophytes are plants that depend on ground water within reach of their roots for their water supply. More than 70 species of plants have been classified as phreatophytes (Kobinson, 1958, p. 1).

Phreatophytes are plants ...Groundwater resources and groundwater dependent ecosystems are threatened by a changing climate. This paper is an assessment for the current knowledge of the impacts of climate change on these climatic scenarios and the adaptation options for management.Although all hickories are noted for the development of a taproot, it is unclear if all Carya species are accurately classified as phreatophytes. In their study of a population of oaks and hickory in central Missouri, Parker et al. (1982 ) provide evidence that C. tomentosa , a species common on mesic sites, may use drought avoidance strategies.Given their high root plasticity, phreatophytes generally have a flexible water use strategy; that is, the water source for plant use can switch between soil water and groundwater by regulating root growth as the degree of soil water stress changes (Gou and Miller, 2014; Soylu et al., 2017). Numerous studies have revealed that phreatophytes ...The xeric phreatophytes, Atriplex tor-reyi and Chrysothamnus nauseosus, survived 6 months of. flooding by growing new roots with aerenchyma (Groeneveld and Crowley 1988).

Currently, however, few models can fully depict the complex water use strategies of phreatophytes. Evapotranspiration (ET) of groundwater may occur when the water table is close to the land surface or when phreatophytes draw water from below the water table. The Evapotranspiration Package requires the user to assign a maximum ET rate (RETM) to each cell from which ET may occur. The maximum rate is used when the water table in a cell equals ...
