The subsurface stormflow is considered as the fast moving component of subsurface runoff of which only a little information is available due to its complex mechanism of movement through subsurface. Hence, this study has taken up for absorbing more knowledge on the phenomenon of subsurface stormflow with the help of tracer method. The experiment has carried out on an experimental plot in the KCAET campus, Kerala, India. The salt tracer experiment is carried out by line application 120 ppm sodium chloride solution on a shallow trench upslope to an excavated through-flow trench. The EC values on the trench face are monitored using the TEROS 12 sensors at three depths (0-40 cm, 40-80 cm and 80-120 cm). The subsurface stormflow velocities through 0-40 cm, 40-80 cm and 80-120 cm depths obtained were 27.27 cm day-1, 30 cm day-1 and 26.67 cm day-1 respectively. It is found that the velocity of subsurface stormflow exhibits a negative correlation with the soil dry density.
