  • 2D beach slope stochastic modelling

    At the Paste 2015 conference in Cairns, we saw a paper presented called Stochastic beach profile modelling. In this paper, the authors developed a statistical model of thickener performance and equated this to beach slopes.  On a daily basis, a volume of tailings was deposited drawing a beach slope from this statistical distribution. A total of 365…

  • More 2D stochastic slope modelling

    In the previous article, a simple statistical model was created to generated different beach slopes on a daily basis.  These beach slopes were deposited using a simple 2D model, and based on many deposition runs, a concave beach slope was found to emerge. In this tutorial, we’ve going to implement the statistical model outlined by…

  • 3D stochastic beach slope modelling

    In the previous tutorial, a stochastic slope model based on the approach presented by Seddon et al (2015) and implemented for a simple 2D deposition model.  In this tutorial we’ll take the same model and implement it for 3D tailings deposition. Seddon, KD, Pirouz, B & Fitton, TG 2015, ‘Stochastic beach profile modelling’, in R…

  • Defining tailings beach slopes within a script

    If you’re writing a deposition script and want to vary the beach slopes of tailings (perhaps for sensitivity analysis), there are a couple of ways to do it. If there’s a specific set of slopes that you’re wanting to run, then it might be easy to simply define a number of different tailings streams in…

  • Defining tailings properties for linear tailings slopes

    This video shows how to define a linear tailings slope.  Different slopes are applied above and below water. Tailings beach slopes are expressed as % as a decimal fraction.  1% is entered as 0.01.
