A New Modified Replacement Method for Discrete Element Modelling of Rockfill Material

Rockfill, a granular material with particle sizes usually in the range of 2 cm to 1 m, is a commonly used construction material in a range of civil engineering applications. Rockfill’s complex behaviour mainly stems from its inherently large particle size grading on one hand and its discrete and heterogeneous nature on the other hand.

Evidence for Microbial Mediated NO3 − Cycling Within Floodplain Sediments During Groundwater Fluctuations

The capillary fringe is a subsurface terrestrial-aquatic interface that can be a signiﬁcant hotspot for biogeochemical cycling of terrestrially derived organic matter and nutrients. However, pathways of nitrogen(N)cycling within this environment are poorly understood, and observations of temporal ﬂuctuations in nitrate (NO3−) concentrations lack the necessary resolution to partition between biotic or abiotic mechanisms.

A geochemical investigation of hydrologically derived threats to rare biota: the Drummond Nature Reserve, Western Australia

The Drummond Nature Reserve (DNR), a high-value conservation area 100km northeast of Perth, Western Australia, contains two rare freshwater claypans and a diverse range of rare and threatened vascular plants. Groundwater/surface-water interactions were investigated via isotopic (δ18OandδD) and major ion analysis.

Water Management and the Global Industry Standard on Tailings Management

In January 2019 the Brumadinho Tailings Storage Facility (TSF) failed, resulting in the deaths of 270 people. This was the second major fatal TSF failure in four years, which led to an industry-wide review of tailings management and the subsequent release of the Global Industry Standard on Tailings Management (the Standard) in August 2020.

Non-Newtonian Tailings Dam Break Analysis and Released Volume Estimation Using Site-Specific Parameters

A series of major tailings dam break events have been recorded across the world in recent years. A breach in the impounding structure of a Tailings Storage Facilities (TSF) can lead to catastrophic environmental, social and economic impacts and potentially result in the loss of human lives.

Comparison of Linear and Central Distribution Systems for Thickened Tailings Stacking

One of the key parameters in successful implementation of thickened tailings schemes for tailings management is the achievable tailings beach slope. Study of geomorphology and hydrodynamics of tailings beaches has shown that the achievable beach slope is directly proportional to tailings solids concentration (i.e. rheology) and inversely proportional to discharge flowrate.

Paste and Thickened Tailings Transportation: Design Aspects Overview

Tailings transport is an integrated element in any wet tailings storage facility (TSF). Tailings from the process plant are often thickened to a moderate or relatively high (but still pumpable) solids concentration, depending on several parameters mainly the TSF deposition requirements and strategies, process plant water security status and the dewatering technology utilised.

Integrated Project Risk Management for Residential Recycled-Water Schemes in Australia

In recent years, the Australian water sector has been criticized for in adequate project risk management and over investment in inefﬁcient water services, such as large desalination plants and recycled-water schemes.

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.
