How does GIS for Water Leak Detection Work? - The Water

Moreover, the dielectric constant (relative permittivity) of pure water makes it easy to detect a leak. With the increase of the dielectric constant, the electric flux density will increase. (Remember that microwaves are electromagnetic waves!) Water has a high dielectric permittivity, which enables the detection and measurement of water in soil.Get price
