Success Stories

June 22, 2007

This application of SVFlux involved the calculation of a water balance for a tailings facility close to Queensland, Australia. Flow past the earth dams had been measured in the field and the desire was to see if a numerical model could accurately predict the flow in a blind test.

The climate in the area is semi-arid with an annual rainfall of 702 mm/yr and a potential evaporation rate of 1650 mm/yr.

General diagram of the Queensland facilityThe tailings were hydraulically placed behind an engineered embankment 5.8 km long. In the middle of the tailings is a 100 ha pool. Overall the tailings covered an area of over 400 ha. Depths of the tailings ranged from 32m to 1m.

 

The tailings are subject to the water balance components of precipitation, evapotranspiration, infiltration, runoff, recharge, and seepage. They are also partially unsaturated which implies a certain non-linearity of flow.

Numerical modelingNumerical modeling was difficult due to the highly irregular 3D geometry and the non-linearity of the unsaturated flow. It was also desired to couple in the calculation of actual evaporation.

A series of 1D and 3D numerical models were created in order to properly model the scenario. Specifically a three-zone 3D numerical model was used to represent the tailings facility. The modeling was successfully completed in under two weeks time and results matched the field measured results with an error of less than 5%.

The SVFlux software allowed reasonable solution to the water balance calculations in a faster-than-expected time period. I would recommend the product for this type of application.

Testimonials

  • "I would like to thank you for all the support and the interest that I got from your team regarding this matter. I was able to successfully finish my project with the help of your technical support and managed to graduate achieving a high grade on the project I did. The software is extremely helpful and wasn't complicated and I look forward to future for more work and experience with your software. Thank you for your help and support."
  • "I have been using SoilVision's SVOFFICE™ software for research and training purposes for a number of years now. Myself and my colleagues have developed a number of training modules in this software, and have been using these to teach limit equilibrium and flow modeling to undergraduate students in the civil, environmental and mining engineering streams.

    In my opinion, this software is easy to learn and fun to use. The built-in tutorials are sufficient to get one started. With these tutorials, my students were generally able to complete their analyses with minimal involvement on my side.

    Based on my own experience, it takes around a month of full-time use to become reasonably competent with the software (provided that one understands the theoretical underpinnings of this type of analysis) - a short learning curve, compared to other products of similar complexity. The interface is intuitive enough for me to figure out things on my own, and I rarely had the need to ask for help.

    I don't generally like praising anything excessively, and I don't post particularly glowing reviews for anything. Having said that, I must mention the SoilVision support. At some point during my research, I was conducting a number of replication studies for my thesis. In that period, I must have emailed SoilVision's support anywhere from 2 to 5 times a day, with fairly complex (and sometimes very dumb) questions. I always got a response by the end of the day, and a resolution within a couple days at most. In a number of urgent cases (such as during a tutorial session with a classroom of students) I called them directly on the phone and, with senior product engineers involved, had the issue addressed in minutes."
  • "We have allowed our students the choice of using multiple Geotechnical software suites in our Dam Design and other Geotechnical courses. Our students consistently gravitate towards SoilVision software as being the most modern and user-friendly."

  • "I've been a geotechnical engineer for more than 25 years and SoilVision has the best tech support I have ever worked with. I truly appreciate their patience and help over the past year."

  • "Peter Brett Associates have been looking to update our existing slope stability software over the last year. After extensive research and trials, SVSLOPE® developed by SoilVision Systems Ltd. was found to meet all our existing and future design requirements. Its ease of use for modeling simple as well as complex geological and geometrical problems was a critical factor in our assessment as well as the incorporation of design to the Eurocodes. Their customer support has been faultless and their willingness to develop the software to meet our own specific design requirements is a most gratifying added bonus."

    "We love the fact that SVSLOPE® is part of an integrated suite of software and that, if required, 3D analysis can be undertaken. We would recommend this product to other geotechnical consulting firms."

  • "We have been using SVSLOPE® and SVFLUX™ for the past year and have found them to be efficient and productive engineering tools which have allowed us to offer our services in an efficient manner. The capability of automated increased discretization of the mesh is an absolute benefit to our modeling, reducing time and effort. We have found the software quick and easy for our engineers to train and utilize. I would recommend this product to other geotechnical consulting firms."

  • "The software is well documented and comes with number of useful example models. We were able to quickly begin creating models after a short review of the user interface and going through the available on-line webinars. The software offers solid benefits of less conservatism and the ability to model real geometry."

  • "This new software for stability analysis includes a number of state-of-the-art options for probabilistic slope stability analysis. This feature, combined with comprehensive deterministic analyses, will provide new opportunities to build confidence in the results of a site-specific analysis.”

  • "I'm excited to see the release of this new and innovative product. I look forward to and encourage the application of this software on additional geotechnical projects.”

  • "In consulting engineering practice, I am increasingly made aware of the important and beneficial role that modeling the unsaturated soil zone can play in providing the client with the best possible engineered solution. The SoilVision software has made it possible to readily estimate and incorporate unsaturated soil properties into the modeling of saturated / unsaturated soil systems.”

  • "The use of SVSLOPE® software as part of a research project on clay slopes under seismic conditions with the Université de Sherbrooke has been incredibly easy and effective. The continuation of this research with SoilVision is promising, with technical support, which was present at the right time, as well as a passionate geotechnical team supporting the project.”
