Acidic groundwater generated from pyrite oxidation in acid sulphate soil (ASS) is a major geoenvironmental problem in Australia. This study aims to evaluate recycled concrete as a reactive material in permeable reactive barriers (PRBs) for the remediation of acidic groundwater in lowlying ASS floodplains. Laboratory experiments were systematically conducted to investigate the acid neutralisatio...

Generation of acidic groundwater attributed to pyrite oxidation in low-lying acid sulfate soil has caused substantial damage the soil-water environment and civil infrastructure coastal Australia. The installation permeable reactive barriers (PRBs) is a frontier technology field neutralisation removal toxic heavy metal cations – for example, soluble iron (Fe) aluminium (Al). This study aims asse...

Present-day river forms and processes are in many cases conditioned by the consequences of anthropogenic modifications such as dams, embankments gravel mining. Fluvial geomorphologists have typically investigated effects these human impacts using a so-called expert-based approach, whereby observed association or synchronicity between geomorphological changes given, preidentified impact, interpr...

Coastal areas are among the most biologically productive, dynamic and valued ecosystems on Earth. They subject to changes that greatly vary in scale, time duration additional pressures resulting from anthropogenic activities. The aim of this work was investigate shoreline evolution main environmental coastal stretch between towns Licata Gela (in Gulf Gela, Sicily, Italy). methodology used inclu...

SUMMARY Distributed acoustic sensing (DAS) enables data acquisition for underwater Earth Science with unprecedented spatial resolution. Submarine fibre optic cables traverse sea bottom features that can lead to suspended or decoupled cable portions, and are exposed the ocean dynamics high rates of marine erosion sediment deposition, which may induce temporal variations cable’s mechanical coupli...

Understanding of morphodynamic processes associated with large-scale floods has recently improved following significant advances modern technologies. Nevertheless, a clear link between flood discharge and in-channel sedimentation remains to be resolved. The hydrological geomorphological data available for the meandering Powder River (Montana, USA) since 1977 makes it perfect laboratory investig...
