1 Introduction. A phreatophyte, which means “well plant” in Greek, is a deep-rooted plant that has the ability to obtain a perennial supply of water from the phreatic zone (or saturated zone) and/or the capillary fringe above the phreatic zone in the soil profile (Meinzer, 1927).Extensive reports indicated that phreatophytic vegetation is widely …Hydrographs from shallow wells in vegetated riparian zones frequently display a distinctive pattern of diurnal water table fluctuations produced by variations in plant water use. A multisite investigation assessed the major controls on theseThe vertical root distribution of riparian vegetation plays a relevant role in soil water balance, in the partition of water fluxes into evaporation and transpiration, in the biogeochemistry of hyporheic corridors, in river morphodynamics evolution, and in bioengineering applications.
