Abstract
A probe for monitoring groundwater flow seepage velocity and direction has an electrical heater and a plurality of temperature sensors located equidistant from the heater. The probe with the heater and temperature sensors is lowered into a monitoring well and positioned so as to be immersed in the groundwater. Energy is sent to the heater, and the temperature response at the temperature sensors is measured and recorded. From the measured response to temperature, the groundwater flow velocity and direction are computed and recorded. The temperature sensors may be resistance temperature detectors, thermocouples, or any other state-of-the-art temperature sensing device.
