|Project opportunity||PhD project with scholarship: Critical zone functioning in semi-arid environments|
Arid and semiarid zones encompass 1/3 of the global landmass and ~70 % of Australia and are frequently characterised by deep groundwater tables and extensive unsaturated zones supporting local vegetation during long dry periods. The project will focus on the uppermost part of the Fortescue River catchment on the southern side of the Hamersley Range in the Pilbara region, WA. The area is covered with an elevated alluvial plain system with a thick unsaturated zone and water table down to <20 m bgl and bushland with several high priority plant species. This region has an extensive groundwater monitoring system and local infrastructure made available by the project industrial partner. Our initial studies in Pilbara have also provided an excellent foundation for the current project.
This project will aim to better understand critical zone functioning in semi-arid environments and specifically focus on (1) determination of evaporative losses from unsaturated zones with respect to sediment and soil properties and water table depths and (2) estimation of the infiltration rates and velocities in lithologically different unsaturated zones.
The West Australian Biogeochemistry Centre, School of Biological Sciences in collaboration with School of Agriculture and Environment and School of Earth Sciences of The University of Western Australia (UWA), are seeking a highly motivated PhD candidate to work on this project. The project is funded from a large-scale study conducted in Pilbara, Western Australia and financed by the Australian Research Council and the industrial partner Rio Tinto Iron Ore.
The PhD student will collaborate closely with the industrial project partner and spend substantial periods working at remote locations in Pilbara. Extensive soil characterisation, moisture evaporative fluxes and infiltration analyses, together with stable isotope composition analyses, will be the key methods used in this study. The project will also contribute to the development of stable isotope and hydrochemical methods and their integration with physical soil moisture monitoring in the unsaturated zone to probe its dynamics, aiming for numerical quantification of hydrological processes in the unsaturated zone. Multiple soil moisture probes and three weighing lysimeters will be available for direct observations and verification of the mathematical models.
