  • 3D Levee intersection analysis

    Levee analysis is becoming an increasingly important topic as the infrastructure ages. Many sections are in need of re-engineering improvements as consideration is given to their replacement. Concepts utilized in their original design are being re-examined. Many of these structures were designed 20 to 50 years ago, and the tools utilized in such analysis have changed significantly. Our ...

  • The Influence of an Integrated Remedial System on Groundwater Hydrology

    ABSTRACT This paper summarizes the development of a remedial system designed to hydraulically contain and ultimately reduce a plume consisting of primarily 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA). The system consists of groundwater circulating wells or extraction wells located in the core of the 1,1,2,2-TeCA plume to provide active source control, combined with monitored natural attenuation ...

  • Oil Sand - Keeping the oil flowing

    Global Water Intelligence looks at the North American oil sands industry, its use of water, and the potential for developing new processing and treatment technologies The majority of oil sands operations are limited to Alberta, Canada, where oil is found in the form of bitumen. According to the Canadian Association of Petroleum Producers (CAPP), there are 173 billion barrels (bbl) of ...

  • River modeling

    When developing regional groundwater models, it is often necessary to represent complex river systems which may exist over a drainage basin. In order to simplify the representation of such river systems in a 3D regional groundwater model, SoilVision Systems Ltd. has implemented a special Rivers object which can be used to represent complex river systems on the top surface of a numerical model. ...

  • Hydrogeological and environmental impact assessment of a geothermal closed loop ground source energy installation

    ESI in Milan was approached to give support for designing one of the largest closed loop systems for heating and cooling in Europe.  The system was installed at the IKEA store in Corsico, Milan, with the need to provide some 1.4 MWth and covering thermal energy demand in the range from 40 to 100%.  The closed loop system is expected to save the Client over 500 t/y in CO2 ...

  • Hydrogeological risk assessment for a proposed landfill

    Client: Waste Management Industry Location: Landfill site, UK Services: Desk study, site investigation and data review, 3D MODFLOW groundwater modelling and hydrogeological risk assessment. Issues: Potential risk to groundwater and surface water, environment and human health.  Landfill containment design ...

  • A mixed-integer non-linear programming with surrogate model for optimal remediation design of NAPLs contaminated aquifer

    A mixed-integer non-linear programming (MINLP) with surrogate model was introduced to derive the optimal surfactant enhanced aquifer remediation (SEAR) process (remediation cost minimisation and removal rate maximisation) at a nitrobenzene-contaminated site. First, a 3D multi-phase flow simulation model was developed to simulate the SEAR process; using a radial basis function artificial neural ...

  • Modeling geothermal wells using SVHeat and SVFlux

    Numerical modeling of geothermal processes has received increased attention in recent years. The process of installing geothermal heating systems in residential homes and cottages is one application of numerical models. These systems typically involve drilling between one and three wells on a particular property. Heat exchangers then act as a pump and remove heat from the ground in order to heat ...

  • Willowstick surveys are applicable and affordable on small projects

    Over the course of Willowstick's eight-year history, we have had the opportunity to work with many prominent clients on large, complex projects. As a result of this, many potential clients have had the perception that Willowstick is "expensive" and not suitable for smaller, less complex projects. While it is generally true that Willowstick's rates might not cost the same as more traditional ...

  • What is so hard about drainage modeling?

    Drainage modeling often suffers from the misconception that it is simple, but while it appears obvious that rain water will flow to the lowest point, the physical processes involved are not always well-understood or predictable. Drainage models attempt to predict that part of the water cycle that involves rainfall and its consequences, including potential flooding. Although flooding is, at its ...

  • Impact of IT on river modeling

    Background Models of river channels and river flows have been used to good effect for many years. HR Wallingford Group, in the UK, has been building physical models of rivers for nearly 60 years. Some years ago, it was predicted that physical modeling would soon cease to exist, to be entirely replaced by computer models. This has not happened - in fact, the demand for physical models is greater ...
