Further elements emerge from analysis of the magnetic data, including linear dipoles which extend for a total of 320 m (Fig.

78), though the dimensions are variable and the interpretation uncertain. The new models correlating ПЃ and Оё under different site conditions are the first set of models based on field data from a loessial region, and their acceptable performance makes them applicable for measuring different soil parameters in the Loess Plateau and possibly other loessial regions around the world. Other less distinct and incomplete circular anomalies can be seen in the graphical representation of the site (Fig. The uncertainty and sensitivity of ERT -derived Оё were further evaluated and acceptable results were obtained. We built linear and nonlinear models correlating ПЃ and Оё and selected the best model according to the coefficient of determination ( R 2) and root-mean-square error (RMSE). /rebates/2farticle2f10.10072fs00020-x&.com252farticle252f10. We obtained 2769 pairs of electrical resistivity ( ПЃ) and Оё datasets using ERT (53 sites) and a neutron probe (69 access tubes) on the Chinese Loess Plateau. A phaseless Gauss-Newton inversion (PGNI) algorithm is developed for microwave imaging (MWI) applications. Therefore, we introduce the noninvasive technique of electrical resistivity tomography (ERT) for indirectly determining Оё through the development of prediction models for loessial regions under different site conditions (i.e., soil texture, land use, soil depth, and dry/wet conditions). Version 3.49 Incomplete Gauss-Newton inversion. However, it is a time-consuming and labor-intensive task that is especially challenging in deep soils. To overcome this problem, the RES2DINV program allows the user to incorporate the effects of the C2.

Acquiring data for the soil water content ( Оё) is important for assessing vegetation growth, drought, and climate change.
