| 500 | _ | _ | |a The research presented in this paper was funded by the Belgian Science Policy Office in the frame of the Stereo 11 programme project SR/00/100 (HYDRASENS), the DIGISOIL project financed by the European Commission under the 7th Framework Programme for Research and Technological Development, Area "Environment" Activity 6.3 "Environmental Technologies," and the Fonds de la Recherche Scientifique (FNRS), Belgium. We thank Faycal Rejiba for his constructive review of the paper. Maxime Dupriez is acknowledged for the field assistance during the field campaign, as well as Guido Rentmeesters for the GPR platform construction. Access to the field was given by Christian Rieulaux, farmer at Walhain-St-Paul. |
| 520 | _ | _ | |a Full-waveform inversions were applied to retrieve surface, two-layered and continuous soil moisture profiles from ground penetrating radar (GPR) data acquired in an 11-ha agricultural field situated in the loess belt area in central Belgium. The radar system consisted of a vector network analyzer combined with an off-ground horn antenna operating in the frequency range 200-2000 MHz. The GPR system was computer controlled and synchronized with a differential GPS for real-time data acquisition. Several inversion strategies were also tested using numerical experiments, which in particular demonstrated the potentiality to reconstruct simplified two-layered configurations from more complex, continuous dielectric profiles as prevalent in the environment. The surface soil moisture map obtained assuming a one-layered model showed a global moisture pattern mainly explained by the topography while local moisture patterns indicated a line effect. Two-layered and profile inversions provided consistent estimates with respect to each other and field observations, showing significant moisture increases with depth. However, some discrepancies were observed between the measured and modeled GPR data in the higher frequency ranges, mainly due to surface roughness effects which were not accounted for. The proposed GPR method and inversion strategies showed great promise for high-resolution, real-time mapping of soil moisture at the field scale. (C) 2011 Elsevier B.V. All rights reserved. |
