Smoothed Particle Hydrodynamics modelling of fresh and salt water dynamics in porous media

Seawater intrusion modelling is often used to assist with groundwater management in coastal areas and islands. Although Smoothed Particle Hydrodynamics (SPH) schemes are able to simulate multi-fluid flows in porous media, they have not been widely tested against experimental observations yet

Exact solutions of the Navier-Stokes equations generalised for ﬂow in porous media

Flow of Newtonian ﬂuids in porous media is often modelled using a generalized version of the full non-linear Navier-Stokes equations that include additional terms describing the resistance to ﬂow due to the porous matrix. Because this formulation is becoming increasingly popular in numerical models, exact solutions are required as a benchmark of numerical codes.

Stochastic modelling of beach profiles including the influence of thickener performance

It is generally well accepted that in the design and operation of thickened tailings storages, ‘better’ thickener performance will improve the beach profile, and thereby enhance the overall performance of the stack.

Expert opinion on risks to the long-term viability of residential recycled water schemes: An Australian study

The water sector needs to make efﬁcient and prudent investment decisions by carefully considering the long-term viability of water infrastructure projects. To support the assessment and planning of residential recycled water schemes in Australia, we have sought to clarify scheme objectives and to further deﬁne the array of critical risks that can impact the long-term viability of schemes.

Analytical and Experimental Investigation of Non-Newtonian Thickened Tailings Slurry Flow through Open Channels

The hydraulic transport of suspensions is frequently encountered in industry. A typical example is mine tailings which are transported from the dewatering plant to the tailings disposal area through an open channel.

An Innovative Approach to Determine Particle Size Distribution for Rockfill Material

Particle characterisation like size distribution and shape can greatly affect the mechanical behaviour of granular materials, and is closely related to the economics for engineering projects. For rockfill material in embankment dam construction, the particle size distribution (PSD) is fundamental to the design, quality control and numerical modelling.

SPH modelling of multi-ﬂuid lock-exchange over and within porous media

Multi-ﬂuid ﬂow over and within porous media occurs frequently in nature and plays an important role in engineering applications. The modeling of these ﬂows and validation against experimental or ﬁeld observations have not been largely conducted in literature. An explicit numerical scheme for incompressible ﬂuid using Smoothed Particle Hydrodynamics (EISPH) was employed and solved using two integration algorithms.

Why do residential recycled water schemes fail? A comprehensive review of risk factors and impact on objectives

In Australia, recycled water schemes have been implemented in residential developments to contribute to sustainable urban development, improve water supply security and reduce pollutant discharges to the environment. A proportion of these schemes, however, have been decommissioned well before the end of their design life which raises questions about the adequacy of the risk assessment and management practices adopted for recycled water schemes.

Open channel transportation of thickened tailings

The mining industry is moving towards thickened tailings with higher density than conventional operations. As a result, tailings transportation is more challenging due to the material’s tendency to exhibit non‐Newtonian behaviour at high solid concentration.
