groundwater modeling training Articles

  • Recent papers in groundwater remediation

    Computational cost is a critical issue for large-scale water resource optimization under uncertainty, since time-intensive Monte Carlo simulations are often required to evaluate over multiple parameter realizations. This paper presents an efficient approach for replacing most Monte Carlo simulations with efficient surrogate models within a noisy genetic algorithm (GA). The surrogates are trained ...

  • Groundwater Contamination Plume Remediation - Case Study

    19 CMT Multilevel Systems Successfully Installed in Challenging  A facility in Pontypool, Wales, UK was once the location of a plastic forming plant. Over time, chemicals produced through the plastic forming processes were lost into the groundwater beneath the facility, creating a large contaminant plume. Years later it was determined that the plume is ...

  • Optimal groundwater management using state-space surrogate models: a case study for an arid coastal region

    A surrogate modeling framework is developed in this study to circumvent the computational burden of high-fidelity numerical groundwater models for arid coastal aquifers. Two different surrogate models, namely, artificial neural network (ANN) and Gaussian process model (GPM) are trained to replace the computationally expensive numerical flow and transport model OpenGeoSys. A novel time-dependent ...

  • Nitrate leaching from a potato field using adaptive network-based fuzzy inference system

    The conventional methods of application of nitrogen fertilizers might be responsible for the increased nitrate concentration in groundwater of areas dominated by irrigated agriculture. Appropriate water and nutrient management strategies are required to minimize groundwater pollution and to maximize nutrient use efficiency and production. Design and operation of a drip fertigation system ...

  • Optimization and economic analysis for a small scale nanofiltration and reverse osmosis water desalination system

    This paper presents the results of a techno-economic investigation of a nanofiltration (NF) and reverse osmosis (RO) process for treating brackish water. Optimization experiments of six commercially available small scale RO and NF membranes were carried out using formulated artificial groundwater. A predictive model was developed by using response surface methodology (RSM) for optimization of ...

  • Decision support for the planning of integrated wastewater reuse projects in South Africa

    Wastewater reuse is an attractive option for supplementing available water supplies. Benefits of reuse include pollution abatement due to the reduction of effluent discharge to surface water bodies, the decrease in the use of freshwaters from sensitive ecosystems, replenishment of soil nutrients in agriculture, enhancement of groundwater recharge and delay in the future expansion of water supply ...

  • A methodology to estimate the future extent of dryland salinity in the southwest of western Australia

    Received for publication January 27, 2009. In the southwestern agricultural region of Western Australia, the clearing of the original perennial vegetation for annual vegetation-based dryland agriculture has lead to rising saline groundwater levels. This has had effects such as reduced productivity of agricultural land, death of native vegetation, reduced stream water quality and infrastructure ...

  • Business development

    One of the primary advantages of the SVOffice geotechnical software suite is that it allows consulting firms to develop new areas of business and revenue streams. This aspect of the software has been demonstrated by Golder Associates Africa. The Midrand office approached SoilVision Systems Ltd. about one and a half years ago with the desire to increase their numerical modeling capabilities. In ...

  • High-Resolution Site Characterization with Multilevel Systems

    Within the last few years, the U.S. EPA added a new focus area on high-resolution site characterization (HRSC) to their Contaminated Site Clean-Up Information (CLU-IN) website. The U.S. EPA’s definition of HRSC is: “High-resolution site characterization (HRSC) strategies and techniques use scale-appropriate ...

  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

  • Lessons learnt and opportunities in alternative European economies

    Recent headlines highlighting the return of Polish migrants indicate the comparative strength of the zloty against the pound. Peter Reich, of URS Deutschland GmbH, Uwe Senftleben of URS Washington Division, Poland and Toby Uppington of URS Corporation look at the opportunities there. While the UK has been in recession, Poland has just registered modest economic growth of 1.1%. When Poland joined ...

  • An Infrastructure Grows · Decentralized Treatment and Recycling Domestic Wastewater

    THE TERM, “decentralized waste-water management,” refers to the process of treating and discharging treated wastewater in the local vicinity where it is generated. Decentralized systems typically use the soil as the final receptor of the treated wastewater instead of discharging to surface waters, which are generally the receptors of treated wastewater from larger centralized treatment plants. ...


  • ON-SITE SEWAGE SYSTEMS: NEW OUTLOOK FOR DECENTRALIZED WASTEWATER TREATMENT

    As researchers analyze the soils’ ability to absorb discharge, more knowledge is gained about alternatives to septic tanks and standard drain fields that include peat filter systems, constructed wetlands and drip irrigation. ONE out of every four American households currently treat and release wastewater on their own property. Although most people assume that on-site systems are confined to rural ...


  • New Jersey Uses GIS, EQuIS to Collect Site Remediation Data

    Using GIS To Manage Remediation Data GIS holds great potential as a tool for managing environmental site remediation data. While using GIS to locate Superfund sites is commonplace, GIS has played only a minor role in the review and analysis of chemical data gathered during an investigation or monitoring activity. There are a number of reasons why GIS has not become commonplace in the ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...

  • A systematic approach for evaluation of capture zones at pump and treat systems

    This document describes a systematic approach for performing capture zone analysis associated with ground-water pump and treat (P&T) systems. A “Capture Zone” refers to the three-dimensional region that contributes the ground water extracted by one or more wells or drains (see Figure 1). A capture zone in this context is equivalent to the “zone of hydraulic containment”. If a contaminant ...
