| Abstract |
A thermal probe for the in-situ measurement of groundwater flow in a borehole was constructed and calibrated in a horizontal position. The probe is a long slender metal rod having a heat source along its entire length and a temperature sensor at its midpoint. When a constant quantity of heat is applied to the probe, the rise in temperature is inversely related to the rate of water flow past the probe. Over 40 calibrations of the thermal probe were made, but most of these tests were used to perfect experimental techniques. However, 8 of the calibration runs were considered sufficiently accurate to construct preliminary Master Curves. These curves indicate that if temperature differences of 0.1 degree Centrigade can be measured at the end of a two hour test, the probe is capable of distinguishing changes in rate of water flow of 0.0005 cucm/sec/sq cm.
