They are usually of small magnitude, but may be very large during solar flares or if supplemented by currents of artificial origin. We carry out a real pumping experiment at a hydrological observation site to verify the proposed method. Orellana and Mooney 1966 published a set of 1,417 two- three- and four-layer Schlumberger curves, accompanied by a set of auxiliary curves, and tabulated values for both Schlumberger and Wenner curves.
Therefore solutes tend to become concentrated in a zone of unfrozen saline water adjacent to soil particles. This is very much influenced by the depths of the features, and the achievable resolution diminishes with depth. This research provides an important theoretical basis for the development and application of train-borne transient electromagnetic method for automatic detection of tunnel defects.

Using this, conductivity appears to be very small for low moisture contents. Pol J Environ Stud 26 1 :17—27• The resistivity values and the curve type at Eka street dumpsite show that the area has an H curve type indicating contaminated zone. In the first type the mineral occurs as fine particles dispersed throughout the matrix, and in the second, the mineral occures in a more homogeneous form. The Ezillo Formation between Appiapum and Ikom was deposited in a deltaic coastal plain, in brackish marshes and inter-distributary bays Barth, et al.
Applying a spatial constraint to the clustering of standardized data increases the number of clusters in order to retrieve spatially tied clusters.

org CALL FOR JOURNAL PAPERS There are more than 30 peer-reviewed academic journals hosted under the hosting platform.
There is an interplay between thickness and resistivity; there may be anisotropy of resistivity in some strata; large differences in geoelectrical section, particularly at depth, produce small differences in apparent resistivity; and accuracy of field measurements is limited by the natural variability of surface soil and rock and by instrument capabilities.
Environ Earth Sci 76 2 :84• To investigate changes in resistivity with depth, the size of the electrode array is varied.
To the extent that differences of lithology are accompanied by differences of resistivity, resistivity surveys can be useful in detecting bodies of anomalous materials or in estimating the depths of bedrock surfaces.
