  • Marine hydrogeology: recent accomplishments and future opportunities

    Marine hydrogeology is a broad-ranging scientific discipline involving the exploration of fluid–rock interactions below the seafloor. Studies have been conducted at seafloor spreading centers, mid-plate locations, and in plate- and continental-margin environments. Although many seafloor locations are remote, there are aspects of marine systems that make them uniquely suited for hydrologic ...

  • Hydrogeology - A Global Perspective

    The field of groundwater hydrology and the discipline of hydrogeology have attracted a lot of attention during the past few decades. This is mainly because of the increasing need for high quality water, especially groundwater. This book, written by 15 scientists from 6 countries, clearly demonstrates the extensive range of issues that are dealt with in the field of hydrogeology. Karst ...

  • Uncertainty Analysis of Mound Monitoring for Recharged Water from Surface Spreading Basins

    This study has conceptually reviewed issues related to implementation of a groundwater mound monitoring well (GMMW) for monitoring recharged water from a surface spreading basin with emphasis on uncertain hydrogeological conditions. For this, we selected a recharge site in the City of Mesa, Arizona, that is characterized with near surface clay lenses of low permeability. A geostatistical ...

  • WMU Field Course Preps Future Hydrogeologists with Hands-On Experience

    Overview Students from around the country sign up for the Hydrogeology Field Course at Western Michigan University in order to gain experience with equipment and applications that will prepare them for the workplace in ways a textbook never could. Challenge In a competitive job market, it stands to reason that students who graduate with the most practical experience in their field will have an ...

  • Extraterrestrial hydrogeology

    Subsurface water processes are common for planetary bodies in the solar system and are highly probable for exoplanets (planets outside the solar system). For many solar system objects, the subsurface water exists as ice. For Earth and Mars, subsurface saturated zones have occurred throughout their planetary histories. Earth is mostly clement with the recharge of most groundwater reservoirs from ...

  • Groundwater flow and transport model of the Estonian Artesian Basin and its hydrological developments

    The sophisticated research and management problems of the Estonian water environment are considered by means of holistic modelling. The model elaborated is based on the computer code Visual MODFLOW Classic. The model encompasses the entire Estonian Artesian Basin (EAB) and the border districts of Russia and Latvia. It involves all main aquifers and aquitards on an area of 88,000 km2. The main ...

  • Fold geometry model of Coyote hills segment of Puente hills blind-thrust system applied to interpretation of long-term water level data

    Recent work by others along the Coyote Hills segment of the Puente Hills blind-thrust system has imaged the near-surface structural features generated by activity of that intrabasin fault. Published shallow seismic profiles near the south flank of the Coyote Hills indicate the blindthrust system is expressed by south-facing folding of Quaternary terrestrial sediments underlying the hills. ...

  • Assessing transmissivity from specific capacity in an alluvial aquifer in the middle Venetian plain (NE Italy)

    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. This paper presents an empirical relationship between ...

  • Well-Field Mechanics for In-Situ Mining

    Over the last several decades in-situ leach mining has become increasingly popular. Conventional mining produces tailings, runoff, and considerable land disturbance—all requiring significant rehabilitation. With in-situ leach mining methods (see diagram below), disturbance is reduced because only multiple boreholes are drilled for recovery. Rehabilitation is much simpler, consequently, the ...

  • GLM and joint GLM techniques in hydrogeology: an illustration

    In regression models with positive observations, estimation is often based on either the log–normal or the gamma model. Generalised linear models and joint generalised linear models are appropriate for analysing positive data with constant and non–constant variance, respectively. This article focuses on the use of these two techniques in hydrogeology. As an illustration, groundwater quality ...

  • Aquifers and hyporheic zones: Towards an ecological understanding of groundwater

    Ecological constraints in subsurface environments relate directly to groundwater flow, hydraulic conductivity, interstitial biogeochemistry, pore size, and hydrological linkages to adjacent aquifers and surface ecosystems. Groundwater ecology has evolved from a science describing the unique subterranean biota to its current form emphasising multidisciplinary studies that integrate hydrogeology ...

  • Investigating the permeability of fractured rock masses and the origin of water in a mine tunnel in Shandong Province, China

    The coastal Sanshandao mine is threatened by the overlying Quaternary water and seawater. Following an introduction to the geology and hydrogeological conditions in the mine area, a detailed hydrogeological survey and sampling were conducted and hydrochemical and stable isotopic (δ2H and δ18O) tests on various waters were carried out to characterize the origin of water in the mine ...

  • Three-phase approach to improve deep groundwater supply availability in the Elidar district of Afar region of Ethiopia

    This study provides new evidence on the effectiveness of a combined remote sensing and hydrogeological investigation method for deep groundwater development in complex geologic and geomorphologic situations in Ethiopia. The study was undertaken in the Elidar district of the Afar region of Northern Ethiopia. Due to the water availability and vegetation in this district, the majority of the ...

  • The Effectiveness of Intrawell ground water monitoring statistics

    Abstract   The reality of the new statistical evaluation requirements for ground water at Subtitle D facilities are being felt nationwide. All too often these requirements are resulting in unnecessary increases in ground water monitoring costs and erroneous indications of facility impacts. For example, a common situation faced by many older facilities is that there is ...

  • ATES: a geo-informatics decision aid tool for the integration of groundwater into land planning

    Groundwater is the primary source of drinking water for small municipalities and individuals. However, groundwater can be polluted by almost any land use. Consequently, many governments have acquired groundwater information in the aim of protecting the resource. Nevertheless, the resulting data are often ill-fitted to planning needs. In a previous study, a method was developed to help planners ...

  • Spatiotemporal groundwater level forecasting and monitoring using a neural network–based approach in a semi arid zone

    Forecasting the groundwater level (GWL) of an aquifer is one of the most important tasks in hydrogeology. Such forecasts prove vital to develop better exploitation strategies of water resources and to carry up–to–date groundwater monitoring. In this paper, an artificial neural network (ANN)–based approach, which was based on linear regression model, is presented to simulate and predict both ...
