Ground penetrating radar

Ground penetrating radar (GPR) provides almost continuous, high resolution profiles of the shallow subsurface which cannot be achieved by any other geophysical technique. Applications of GPR in geomorphology have increased significantly in recent years due to an increased awareness of the technique, combined with improvements in the equipment which make it more portable, more reliable, and easier to use. The ease of use has presented some problems due to unrealistic expectations, inappropriate survey design, and questionable interpretations. Examples are included to illustrate common ‘problems’ as well as successful GPR surveys.
