Abstract
The paper presents using of GPR method for location of loose zones in the river embankments. The relationships between the existence of loose zones in the levees, their water-saturation and changes in the electromagnetic properties in the ground were discussed in the paper. There is proposed in the paper changeable-offset profiling, which gives wider possibilities in GPR detection of loose zone distribution in levees than standard, zero-offset, reflection profiling.
