In lieu of the uniform resistivity, the table down below signifies a simple two-layer soil design. The ensuing plot from SRA demonstrates the steep downward slope as the resistivity changes from bigger resistivity to decrease resistivity. Thanks for the inquiry. The Barnes layer system can be a theoretical assemble according https://landsurveyingprofessional76653.total-blog.com/soil-resistivity-testing-laboratories-bd-options-57577166
