oa Ground penetrating radar in pipeline river crossing design. A case study from the jungles of Ecuador

A ground penetrating radar (GPR) survey was conducted to delineate sub-bottom geological strata for a pipeline river crossing project in Ecuador. The primary purpose of this investigation was to map a thick gravel layer underlying sands and silts to a total depth of over 40 metres. Despite significant depth requirements and logistical difficulties, radar data of excellent quality were acquired. This allowed the production of river crossing profiles which were believed to be of greater accuracy and detail than those generated by traditional geotechnical methods.
