Methods for determining the parameters necessary for modeling fluid flow and contaminant transport in the shallow subsurface are in great demand. Soil properties such as permeability, porosity, and water retention are typically estimated through the inversion of hydrological data (e.g., measurements of capillary pressure and water saturation). However, ill-posedness and non-uniqueness commonly ...

Understanding how geophysical and hydrologic properties are related is a key problem in hydrogeophysical data fusion. Traditionally this link has been made by rock physics investigations that define how pore-scale variations in properties like mineralogy, fluid content, and grain geometry affect the geophysical response of a rock or sediment. As the scale of investigation increases from the lab...

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...

Abstract The mining of stratified ore deposits requires detailed knowledge the location orebody boundaries. In Banded Iron Formation (BIF) hosted iron located in Pilbara region Western Australia natural gamma logs are useful tool to identify stratigraphic However, manually interpreting these features is subjective and time consuming due large volume data. this study, we propose a novel approach...

Different methods of lithology predictions from geophysical data have been developed in the last 15 years. The geophysical logs used for predicting lithology are the conventional logs: sonic, neutron-neutron, gamma (total natural-gamma) and density (backscattered gamma-gamma). The prompt gamma neutron activation analysis (PGNAA) is another established geophysical logging technique for in situ e...

In this report we introduce the development of the WDC for Geophysics, Beijing included our activities in the electronic Geophysical Year (eGY) and in the transition period from WDC to WDS. We also present our future plans. We have engaged in the development of geophysical informatics and related data science. We began the data visualization of geomagnetic fields in the GIS system. Our database...

Geophysical Prospection has yielded remarkable results to the research in Archaeology. Besides the recognition of places, also the earlier uses of a site can be reconstructed. Therefore, the geophysical techniques help to understand the layout of a site and raise new research questions. In this paper, we summarize the main geophysical prospection methods for archaeology: magnetic, radar and res...

The genetic algorithm is of advantages to solve an inversion of complex non-linear geophysical equations. Its multi-point searching is able to find the globally optimal solution and avoid falling into a local extremum. The searching efficiency of the genetic algorithm is a key to successfully resolve a geophysical inversion problem in a huge model space with multi-parameters. Encoding mechanism...
