.... In some instances, drinking water wells more than 10 m deep dry up when irrigation wells are pumping but recover when irrigation ceases ( Banks and Soldal, 2002 ). These irrigation wells were initially developed to help local farmers deal with drought conditions. The owners of these wells report...

... formed along field boundaries. These eolian deposits accumulated episodically in the late Pleistocene and Holocene and provide clues to the history of regional drought and aridity. The earliest phase of sedimentation occurred when sheet sands were deposited between 11 000 and 8000 14 C yr B.P., probably...

... sediments dated by radiometry ( 14 C, 137 Cs, 210 Pb) and pollen stratigraphy indicate that salinity in mesohaline regions oscillated 10–15 ppt during periods of extreme drought (low fresh-water discharge) and wet climate (high discharge). During the past 500 yr, 14 wet-dry cycles occurred, including...

TIGGER Ha is concerned with proxy records of climate change over the last two millennia and their application at a time...

... to the three principal solar-oscillation periods (420, 218, 143 yr) as inferred from the atmospheric radiocarbon record, suggesting strong solar forcing of century-scale drought frequency with a fundamental 400-yr period and its 2nd, 3rd, and 4th harmonics. Our proxy record correlates visually...

..., these data indicate that the Minot dune field may have had extended periods of activity in the Holocene, such that eolian abrasion removed soft carbonate minerals. The southwest-facing parts of some presently stabilized dunes were active during the 1930s drought, but were revegetated during the wetter years...

We present a case from the northern Great Plains in which Holocene drought response recorded in lake sediments was determined...

... slowing exponentially over 4 yr. Movement began after a wet winter of ≈100-yr return period, but a previous drought may have hastened the movement. The sequence of dry summer and wet winter had a 1 in 1500-yr recurrence interval. A favored hypothesis for the role of drought is desiccation cracking...
