Ground temperature aids in measuring water levels

MADISON, WI, FEBRUARY 7, 2003 - Scientists have discovered an unusual way to measure how fast water moves from the ground surface to the water table: they analyze the ground temperature.

Research in Vadose Zone Journal, published by the Soil Science Society of America, describes the methodology behind using temperature to analyze how much water is recharging the ground water at a specific location. The research describes scientific results for field sites in New Mexico and Nevada, where researchers have discovered that borehole measurements of temperature between the surface and the water table aid in measuring how fast water moves to the underlying water table.

"How rapidly this water moves determines the amount of water that can be pumped without using more water than can be replenished by precipitation and streams, which has remarkable impacts for irrigation," said Jim Constantz, U.S. Geological Survey, California, who collaborated with Scott Tyler, University of Nevada, and Ed Kwicklis, Los Alamos National Laboratory, New Mexico.

They examined deep temperature data under Yucca Mountain and French Flat, Nevada, and shallower temperature data in the Rio Grande Basin of New Mexico. When comparing temperature-based measurements of water movement for mountainous, valley, and intermediate locations, there was an enormous range in rates of water movement toward the underlying water table. Beneath desert streams the downward movement of water was as high as several feet a day, while in deep arid basins the movement of water was no more than a fraction of an inch a year or less.

In the future, routine measurements of ground temperature may lead to widespread identification of the cumulative rates of water movement toward the water table, permitting water to be pumped at a rate that does not exceed the rate of ground water recharge. This could lead to the sustainability of ground-water resources for future generations in the Southwest, acc
