China is a typical developing country. Risk management has become an inevitable trend in China's geologic hazard management and it is imperative to conduct geologic hazard risk evaluation. Although China has laid the foundation for geologic hazard survey and zoning, the large-scale geologic environment information is not fully available and the geologic hazard risk evaluation must be pressed ...

The most critical moment is the choice of a site for radioactive waste geological repository. Here the role of engineering and geological prospecting as a basis for the construction of a facility for underground isolation appears especially important; it is followed by finding a suitable area and subsequent allocation of the site and facility construction sites. The decision on the selection of ...

Critical water-resources issues ranging from flood response to water scarcity make access to integrated water information, services, tools, and models essential. Since 1995 when the first water data web pages went online, the US Geological Survey has been at the forefront of water data distribution and integration. Today, real-time and historical streamflow observations are available via web ...

A reflection seismic survey was performed in the city of Lausanne (CH) to map geological layers relevant to geothermal energy production. By using a wireless seismic system and a powerful seismic vibrator source we were able to high quality results despite the presence of elevated urban noise levels. The new subsurface maps allow the estimation of the geothermal potential for the city of ...

In August of 2005, Willowstick Technologies, LLC performed an AquaTrack study at the Teapot Dome oil field near Casper, Wyoming. The project was performed together with the assistance of the Rocky Mountain Oilfield Testing Center (RMOTC), a unit of the United States Department of Energy. The purpose of the project was to demonstrate how the AquaTrack technology can be applied to ...

The US Department of Energy (USDOE) facilities encompass large tracts of land that include important regional ecological resources. The historical development and continued operation of these facilities has changed the structure of regional landscapes. A quantitative analysis was performed to determine if patterns of land use within the boundaries of selected USDOE facilities could be ...

The purpose of this surface electrical resistivity survey was to delineate the event direction of a gold ore deposit. The surface electrical resistivity survey uses a 10m interval cable, that permits the FlashRES 61 channel resistivity meter to detect depth up to 120m. The depth is dependent on the cable length.  The system found an occasional resistive band from 0-350m. This knowledge was ...

The Patomsky crater is located in east part of the Irkutsk region (Russia). This geological object has anomaly appearance and is discordant placed relative to hosting geological structure. The crater has been discovered in 1949 during routine geological survey of the territory by geologist V.V. Kolpakov. The drastic investigations of Patomsky crater by modern technology have begun since 2006. The ...

Surface borehole method can be used to effectively maximise the value of existing boreholes. This is because surface-boreholre method can give operator more geological and geophysical information around the borehole. For example, we did a surface-borehole survey, where there was already well-known mineralisation existing between 60-80m in Figure one and 100-115m. The inversion resistivity ...

In April 2011, our client had four unsuccessful drilling wells before our company participated in this project at Blackjack Ranch, Llano. After geological analysis, we conducted the seismoelectric survey along the fracture direction and provided our client a well location with 5 gallon/hour water production which proved by later ...

The 1991 C. A. Hogentogler Award was presented to David I. Stannard of the United States Geological Survey in Denver, Colorado. The Hogentogler Award is presented to the author or authors of a paper of outstanding merit on soil or rock for engineering purposes published by the Society. The award was established in 1953 to stimulate research, encourage the exchange of knowledge, and recognize ...

Catastrophic events generate cascading and synergistic infrastructure failures that will produce unanticipated response requirements. Infrastructure failures not only influence the demands for services and commodities but also the mobility and capability of response organisations. This project modelled a catastrophic earthquake (M7.7) in the New Madrid Seismic Zone (NMSZ). The US Geological ...

1. Introduction RaMPS, which stands for Resistivity Mono-pole Profiling and Sounding, is a unique and proprietary geophysical survey and exploratory methodology developed by Willowstick Technologies by combining traditional resistivity sounding and profiling techniques into an integrated surveying method. It is not only unique in the way the data is acquired, but unique in the way the ...

During September 20–21, 2009, over 18 inches of rain fell in Acworth, Georgia. The U.S. Geological Survey called this an epic 500-year flood for the area and one of the worst floods in the U.S. during the past 100 years. The flooding caused the local drinking water treatment plant, Cobb County-Marietta Water Authority, to see a rapid decrease in the Allatoona Reservoir source water ...

This exploration survey used the cross-hole resistivity method to detect if there was industrial waste water leakage from an industrial waste water process pond. Chemical analyses concluded that this specific waste water has a much lower resistivity than normal water. The figure below shows that the area above 45m is a relatively high resistive zone made of limestone. Below this depth is a middle ...
