Disclosed is a monitoring probe for observing groundwater, which is put into an observation well for observing the groundwater to indicate a position of a fresh water-salt water interface of the groundwater. According to the present invention, both ends of a probe body are separated from an inner circumference of an observation well by a catch preventing portion having a convex curved portion or a dumbbell-shaped portion, so that the probe body can be smoothly moved up and down without being caught by a ground-water inlet port of the observation well, thus providing an exact position of a fresh water-salt water interface.

There is provided a water exchange meter being capable of automatically and continuously measuring the water exchange at the surface water/sediment interface in which a saturated vertical hydraulic conductivity of the sediment from the hydraulic head difference between a chamber and a storage pipe at a measurement location is measured, and after the measurement of the saturated vertical hydraulic conductivity, while the measurement device used in the measurement of the vertical hydraulic conductivity is maintained, a vertical hydraulic gradient between upper and lower portions of a chamber is continuously measured in situ.
