Ground-penetrating radar has been used to detect and map tree roots using surface-based antennas in reflection mode. On amenable soils these methods can accurately detect lateral tree roots. In some tree species (e.g. Pinus taeda, Pinus palustris), vertically orientated tap roots directly beneath the tree, comprise most of the root mass. It is difficult if not impossible to vertically delineate...

[1] Estimation of the three-dimensional (3-D) distribution of hydrologic properties and related uncertainty is a key for improved predictions of hydrologic processes in the subsurface. However it is difficult to gain high-quality and high-density hydrologic information from the subsurface. In this regard a promising strategy is to use highresolution geophysical data (that are relatively sensiti...

The crosshole ground penetrating radar (GPR) is a widely used tool to map subsurface properties, and inversion methods are derive electrical parameters from GPR data. In this paper, probabilistic algorithm that uses Markov chain Monte Carlo (MCMC) simulations within the Bayesian framework implemented infer posterior distribution of relative permittivity medium. Close attention paid critical ele...

Abstract A geophysical Bayesian inversion problem may target the posterior distribution of geological or hydrogeological parameters given data. To account for scatter in petrophysical relationship linking to properties, this study treats intermediate properties as latent (unobservable) variables. perform such a variable model, intractable likelihood function (hydro)geological data needs be esti...
