Assem. Suppl., Abstract H33B-06, 2005. Consumption of ground
water by phreatophytes in riparian corridors is thought to be
one factor responsible for stream-flow reductions in western
Kansas and elsewhere. Extensive phreatophyte-control measures,
primarily focusing on invasive species such as salt cedar and
Russian olive, are being considered in response to concerns
about the impact of phreatophytes on surface-and ground-water
resources. At present, there is no generally accepted means of
quantifying the ground-water savings that might be gained
through these control measures. Micrometeorological methods are
often not appropriate for this application because their fetch
requirements are too large for narrow riparian corridors.
Recently, an approach based on diurnal fluctuations in the water
table has been shown to have potential for quantifying ground-
water consumption by phreatophytes. A d
