Georadar measurments for Statens Vegvesen at Kistefoss - Kleggerud and Roa, Jevnaker and Lunner kommuner

Abstract

In October 2015, the NGU conducted Georadar measurements in two locations: at Kistefoss - Kleggerud just south of Jevnaker in Jevnaker municipality and north of Roa in Lunner municipality, Oppland county. The survey is funded by the Norwegian Public Roads Administration (Statens vegvesen) and its purpose is to test the method's efficiency in supplementing the construction of new roads. More specifically, our main goal is to discover the maximum thickness of sediments and delineate the depth at which bedrock lies.All measurements have been handled by Georgios Tassis from NGU and Tore Thomassen from Statens vegvesen. Two Georadar systems have been employed for this purpose: Pulse EKKO PRO by Sensors & Software and RTA by Malå. All measurements were resumed in three days during the 10th and 12th of October 2015. This report presents the measurement scheme (method, execution and processing) along with all the processed radargrams which resulted from the measured profiles. Each profile is accompanied by commenting on the results while the profiles themselves are presented in 1:1 scale (depth scale equal to distance scale) in three Appendices.
