The Actively Heated Fiber Optic (AHFO) method is shown to be capable of measuring soil water
content several times per hour at 0.25 m spacing along cables of multiple kilometers in length. AHFO is

The heat pulse probe method can be implemented with actively heated fiber optics (AHFO) to obtain distributed measurements of soil water content (θ) by using reported soil thermal responses measured by Distributed Temperature Sensing (DTS) and with a soil-specific calibration relationship. However, most reported applications have been calibrated to homogeneous...
