2D beach slope stochastic modelling
—
by
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
—
by
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
—
by
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.
