Webbsuccessfully used underwater ERT for surveying and quantifying potentially polluted sediments in waterways. Orlando (2013) studied the performance and limits of ERT for detection and characterisation of thin near-bottom sedimentary layers, where the analysis included the resolution of floating and submerged electrode cables. Webb21 jan. 2024 · Marine ERT data are collected using continuous profiling with a reciprocal Wenner–Schlumberger array and 13 electrodes (10 potentials measured simultaneously for each current injection). The electrode spacing is 15 m, and measurements are repeated every 5 m from 175 to 835 m, with a total of 133 electrodes (970 data points).

Carrying Out Topographic, Single and Multibeam Bathymetric, Hydrographic Survey, Geophysical Survey, Geotechnical Investigation, Seismic Refraction, Pressuremeter, Cross Bore Hole and ERT Test. WebbThe ERT (Electrical resistivity tomography) is a method to map the resistivity of subsoil materials using a DC current injected from a resistivity-meter. The method produces models that reproduce the electrical resistivity in the ground, allowing to derive qualitative information on the type of geologic material and the water content therein. eagle lighting solar lights
