Efforts to delineate underground mine workings in the vicinity of tailings impoundments has relied on available maps and confirmatory boreholes. Often the characterization of regions between boreholes remains suspect or entirely unknown. Surface geophysical measurements can be used to supplement the borehole data and better delineate these intermediate zones. Furthermore, geophysics can be used...
Multi-channel Analysis of Surface Waves (MASW) is a seismic wave propagation method which involves the measurement of Rayleigh waves propagating along the surface of a medium. The method is non-intrusive, fast and practical and it has been successfully utilized for the in-situ evaluation of shear modulus and layer thicknesses of soils and, more recently, pavement systems. The method is also wid...
The analysis of foundation vibrations and geotechnical earthquake engineering problems in civil engineering requires characterization of dynamic soil properties using geophysical methods. Dynamic structural analysis of the superstructures also requires knowledge of the dynamic response of the soilstructure, which, in turn relies on dynamics soil properties. Machine vibrations, blasting and seis...
296 A wellfield (Boise Hydrogeophysical Research Site or BHRS) is being developed in Boise, Idaho, for hydrologic and geophysical research in a shallow, coarse (cobble-and-sand), alluvial aquifer. Our goal is to develop cost-effective methods for quantitatively characterizing the distribution of permeability in heterogeneous alluvial aquifers using hydrologic and geophysical techniques. Respons...

Geophysical phenomena of interest to geoscientists include both atmospheric and terrestrial related processes, which can be either static or dynamic. Characterization of such phenomena requires advanced models which often include scale invariance concepts of fractal or multi-fractal type. Recently, there has been much interdisciplinary interest in the application of geophysical processes. The a...
We review several aspects of the mathematical theory of wave propagation in random media with particular emphasis on topics of geophysical interest.
Background Cardio-vascular pathology is widespread in the North. It is more severe and hard than in moderate latitudes. There are little data available describing reactions of cardio-vascular system to changes of climatic, meteorological and helio-geophysical factors and their role in the development of the disease. The purpose of our study was to study the role of pathological reacting to clim...
Hydrogeologists have long been interested in using geophysical measurements to answer questions about the Earth. Originally used to find ore bodies or oil and gas, geophysics’ sensitivity to water was originally considered a nuisance. While looking for metallic ore using electricalinduced polarization, for instance, early geophysicists found that groundwater controlled most of the measured sign...
