groundwater quality characteristics are affected by lithology and geological structure of aquifer formations. this research has studied the groundwater chemical quality of the upper aji-chai basin with regard to different geological formations. using pie and piper diagrams, the researchers analyzed hydro-chemical elements of 47 sample groundwater resources. after determining water type of sampl...

Accurate decision-making in the petroleum industry is highly contingent on building a reliable model of the subsurface geological structure. Building a model of the subsurface typically involves solving an inverse problem with acquired data for various model parameters of interest like P-wave velocity, rock porosity etc. However, issues of poor data quality necessitate regularizing the inverse ...

According to EuroGeoSurveys, the European Geological Surveys association, “Geological spatial data and models describe the solid Earth’s surface and subsurface on-shore and off-shore, its nature, structure, properties, dynamics and evolution over time; including its related (geo)resources and (geo) hazards”. This illustrates a modern vision of the core mission that National Geological Surveys h...

Faults are the most critical tectonic factors in geological structures, which have major economic impacts on mining economics. Thus it is necessary to understand faults in order to identify the actual risks and complications associated with mining. In the preliminary investigation of the Sonda-Jherruck coalfield, 3D geological modeling was not performed. The purpose of this work was to perform ...

Recent research has suggested that changes in temperature and precipitation events due to climate change have had a significant impact on the availability and timing of streamflow. In this study, monthly temperature and precipitation data collected over 29 climate divisions covering the entire Colorado River basin and monthly natural flow data from 29 U.S. Geological Survey (USGS) gauge locatio...

The display of three dimensional geological body can visually describe the complex subsurface geological structure, effectively improve the engineer's space imagination and intuitively understand the geological spatial relationship. Through analysis of commonly used three dimensional geological data model and considered the impact of faults. The paper establishes a generalized triangular prism ...
