Wexler Earthfx completed an integrated GSFLOW modelling study in support of an application to extract gravel and bedrock from below the water table by James Dick Construction Ltd. ...
Earthfx Incorporated developed a preliminary regional-scale groundwater model for the entire Grand River Conservation Authority area. The objective of the study was to better understand regional groundwater flow in the GRCA and evaluate the interaction between the river and the various aquifer systems in the basin. A key aspect of the study was the integration of multiple smaller-scale models ...
The desired reporting requirements include hydrogeology models, sampling procedures, geographical locations, documentation of contaminants, analytical methods, analytical results, estimated background concentrations and conclusions. ...
The high-resolution images available from SkyTEM are used to quickly develop a geological model and are used with available ground truth data to adjust, update and improve the geological interpretation and selection of appropriate sites for development. ...
Project Description The Kevitsa open pit mine has been in operation since 2012 and was acquired by Boliden in 2016. A new strategic plan is currently being developed to investigate an increase in production. In conjunction with this, the geotechnical slope design parameters for the final pit depth, including a possibly deeper pit, need to be analyzed. OFFICE Chile Itasca Chile SpA Sweden ...
Project Description This project involved simulating the proposed open pits and underground mining of the Aurora Mine in Guyana, predicting potential inflow rates into the pits and underground workings, and providing pore‐pressure distributions to the geomechanical model. OFFICE U.S. Denver Itasca Denver, Inc. INDUSTRIES CLIENT NAME Guyana Goldfields LOCATION Guyana SOFTWARE ...
Cross-hole flow and shut-in tests in eight NQ-size coreholes were conducted in the basement rock that is adjacent to a fault contact with the overlying 500 m thick sandstone unit. The hydrogeologic parameters of basement rock in the vicinity of a freezing drift were obtained. ...
Project Description Karowe Mine, located approximately 16 kilometers (km) southwest of the town of Letlhakane, is a diamond mine where the second largest diamond ever found on record, with a weight of 1,111 carats, was discovered. This project involved simulating mine dewatering and excavation to evaluate future dewatering requirements, as well as providing guidance for future monitoring borehole ...
The HVSR data were acquired by local field operators, and then processed and depth converted using a Vs of 370m/s, with the modelled bedrock surface ranging in depth from The objective of this presentation is to demonstrate the successful application of the passive seismic HVSR method in assisting with hydrogeological studies by providing ...
A review of all existing data and information relating to the site was undertaken and a hydrogeological conceptual model was produced. The development of the site’s hydrogeological conceptual model highlighted the limited data availability for the site. Recommendations were made to undertake monitoring at the site to ...
On the basis of these results, conceptual models of hydrogeological behaviour were used to describe the spatial and temporal variations in the hydrodynamic and salinity characteristics of groundwater. ...
Modelers typically test alternative conceptualizations of a groundwater system because the ‘true’ hydrogeological model of the system is unknown, and the observed data are limited. ...
Based on this work a Conceptual Site Model (CSM) has been developed detailing the subsurface conditions followed by a preliminary risk analysis. ...
Urban water in Gulf Cooperation Council countries is principally supplied from desalination plants. However, desalination could be interrupted by natural hazards such as cyclones or harmful algal blooms. Four scenarios have been considered to help public institutions in Muscat to establish a water strategy for emergency situations. The numerical simulations of groundwater pumping have shown ...
Defining aquifer permeability distribution accurately over large areas is often debated in hydrogeology. The operational efforts to calculate hydraulic conductivity with classical aquifer tests are significant; however, accurate knowledge of permeability areal distribution is fundamental both from a hydrogeological and a modeling standpoint. ...
For this purpose, a 2–dimentional groundwater flow and solute transport model was developed and calibrated using PMWIN 5.3. Simulation results under steady–state and transient conditions show that the horizontal hydraulic conductivity values range from 1 to 23 m/day; and the specific yield values range between 0.03 and 0.25. After construction groundwater flow ...
The efficiency of the method was assessed by a scenario analysis based on hydrological and hydrogeological models. Multi-criteria simulations revealed the optimum infiltration sites by considering technical and site-specific aspects and the positive impact of artificial recharge on seasonal groundwater budget. ...
Hydrology is the science that deals with the processes governing the depletion and replenishment of water resources of the earth's land areas. The purpose of this book is to put together recent developments on hydrology and water resources engineering. First section covers surface water modeling and second section deals with groundwater modeling. The aim of this book is to focus attention on the ...
Numerical techniques are widely used for modelling groundwater aquifers. Hydrological models are generally concept based and highly non-linear due to complex parameterisation as compared to models of other disciplines. Calibration and validation of such models cannot follow conventional methods borrowed from other disciplines ...
