  • 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 ...

  • Modelling of coastal hydrogeology of Krishna delta in India

    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 many times due to scale of the model domain. In the present paper, ...

  • The future of stochastic and upscaling methods in hydrogeology

    Geological formations are complex features resulting from geological, mechanical, and physico-chemical processes occurring over a very wide range of length scales and time scales. Transport phenomena ranging from the molecular scale to several hundreds of kilometers may influence the overall behavior of fluid flow in these formations. Heterogeneities that cover a large range of spatial scales ...

  • 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 ...

  • Ranking of conceptualized groundwater models based on model information criteria

    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. This study elaborates on how to rank different conceptualizations of a groundwater system by using selection techniques and criteria that make a balance between complexity and accuracy of models. ...

  • Salinity modeling for the Altona sewerage strategy

    City West Water’s Altona sewerage system is possibly one of the most studied sewerage networks in Melbourne, Australia. Currently the tertiary sewage effluent from the Altona treatment plant is discharged to Port Philip Bay with an average salinity of approximately 4500 mg/litre.  This study involved the development of a detailed model that accurately reflected the sources and dilution of ...

  • 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 ...

  • Soil Attenuation Model (SAM) Technical Background Document

    Under a risk-based corrective action (RBCA) process, soils and groundwater impacted by a chemical release are to be remediated or controlled to concentration levels such that further migration will not expose human or environmental receptors to unsafe levels of hazardous constituents. For this purpose, site-specific target levels (SSTLs) must be established for the affected soil mass such that ...


  • Sharpening Your Way to Better Groundwater Models

    There is a well-known fable about a wood cutter who was hired by a timber merchant to cut down trees. This well sought-after job paid well and had excellent working conditions. The wood cutter wanted to succeed in his new job so the first day he worked hard and cut down 18 trees. Determined to do even better on the second day, the wood cutter tried harder but only cut down 15 trees. Day after day ...

  • A refined groundwater flow model of the shallow aquifer in Tianjin Municipality, China

    The assembly of a groundwater flow model for the shallow aquifer in Tianjin Municipality is outlined in this paper. Tianjin Municipality was selected because of its complicated hydrogeological conditions and rich data, which could be used to test a refined groundwater flow model for the shallow aquifer. When a shallow groundwater flow model is being assembled its recharge and discharge ...
