Ground Penetrating Radar (GPR) is a geophysical method that use electromagnetic waves to study subsurface structure in different areas of knowledge as geology, agricultural engineering and civil engineering. The wave penetration on the soil is strongly controlled by electrical conductivity of soil components such clay content, organic matter and water content. In this study, tests were conducted in a flood plain in the Elizabeth Creek watershed (New Jersey – USA). One transect was demarcated and measurements made by two methods: Common Midpoint Profile (CMP) and constant offset profiles (COP) methods, both with 100 MHz antennas. Measurements were also made with 250 and 500 MHz shielded antennas. GPR showed good accuracy to study soil special variability and soil stratigraphy. Antennas with higher frequency had lower vertical investigation capacity and greater accuracy. The main limitation of GPR system is that it is not possible differentiate signals of organic matter and clay.
