New multi-scale seed dispersal models for improved regional weed management. This project will exploit recent advances in ecological and atmospheric modelling with the aim to build improved models of seed dispersal across landscapes to anticipate weed spread. Damaging invasive plants are rapidly transforming landscapes and altering ecosystem function worldwide. The speed and direction of weed spread determines the success or failure of costly containment and control actions, however we lack the ....New multi-scale seed dispersal models for improved regional weed management. This project will exploit recent advances in ecological and atmospheric modelling with the aim to build improved models of seed dispersal across landscapes to anticipate weed spread. Damaging invasive plants are rapidly transforming landscapes and altering ecosystem function worldwide. The speed and direction of weed spread determines the success or failure of costly containment and control actions, however we lack the ability to adequately predict spread. New models that combine micrometeorological measurements, within-canopy turbulence and topographic variation in wind flows will be designed to better predict where dispersal will occur. In this project, these improved predictions are planned to be combined with decision models to direct the management of invasive species across entire landscapes.Read moreRead less
Understanding snow gum dieback for effective and integrated management. The project leverages recent research and infrastructure investments and our determined and collaborative team as it aims to: 1) assess the future geography of snow gum dieback in the high country and identify priority locations for pro-active management, 2) quantify the impact of snow gums on high country water and carbon budgets and thus the socio- economic and biodiversity values, and 3) determine options for mitigation. ....Understanding snow gum dieback for effective and integrated management.

Dieback of our iconic snow gum forests is diminishing the ecological, hydrological and cultural values of the Australian Alps and will impact state and national water-supply and power-generation systems. Our research will inform Alps-wide management efforts designed for long-term success.Read moreRead less

This project aims to use data from a Large Hadron Collider experiment, ATLAS, to investigate basic questions in physics. The project expects to use innovative analysis techniques to test the current model of fundamental particles and interactions. While the model, now completed by the Higgs boson discovery, agrees well with observations it cannot be Nature's ultimate description. Expected outcomes include a sensitive investigation of whether the highest energy particle collisions ever recorded hold evidence for a deeper theory. Significant benefits will be an advancement of fundamental knowledge, cutting-edge training of young scientists, strengthening of Australian participation in international science, and public engagement with science.Read moreRead less

Summary
Bridging the accuracy gap: High-precision parton showers for colliders. This project aims at improving the accuracy of parton showers, which are an essential ingredient used in the simulation of high-energy particle collisions. Parton showers generate the large set of particles produced in a collision, in an approximation of the radiation pattern of Quantum Chromodynamics. The low precision of this approximation translates into large uncertainties in critical measurements performed at particle c ....Bridging the accuracy gap: High-precision parton showers for colliders. This project aims at improving the accuracy of parton showers, which are an essential ingredient used in the simulation of high-energy particle collisions. Parton showers generate the large set of particles produced in a collision, in an approximation of the radiation pattern of Quantum Chromodynamics. The low precision of this approximation translates into large uncertainties in critical measurements performed at particle colliders. This project will study novel ways of enhancing the precision of parton showers, and determine accurate estimates of associated uncertainties across all processes under investigation at the Large Hadron Collider. It will be of exceptional importance for the latter's high-precision, high-luminosity program.Read moreRead less

Experimental measurements will be carried out to validate the new theoretical developments and use them to minimise theoretical uncertainties.Read moreRead less
Building resilient alpine environments with less snow. In this project, we aim to build resilience into alpine National Parks and Alpine Resorts to counter the effects of ongoing declines in snow. Alpine environments depend on snow to regulate water flows, insulate vegetation, control soil erosion and promote proper ecosystem functioning. How these processes will operate in a snow-free future is unknown. We will determine how and where snow characteristics drive soil water availability for plant ....Building resilient alpine environments with less snow. In this project, we aim to build resilience into alpine National Parks and Alpine Resorts to counter the effects of ongoing declines in snow. Alpine environments depend on snow to regulate water flows, insulate vegetation, control soil erosion and promote proper ecosystem functioning. How these processes will operate in a snow-free future is unknown. We will determine how and where snow characteristics drive soil water availability for plants and which plant species have the best adaptation and regeneration potential under extreme conditions such as heat, frost and drought. Benefits of the project include innovative land management and rehabilitation solutions, to safeguard Australia's alpine areas under changing environmental conditions.Read moreRead less
Mitigating extreme water supply contamination in bushfire burned catchments. This project involves Melbourne Water, the Department of Environment and Primary Industries, and East Gippsland Water in developing tools to evaluate mitigation options that will protect our water supplies and increase the resilience of Australian communities to bushfire. Major bushfires in south-east Australia in 2003, 2007, 2009 and 2013 were followed by storms that triggered extreme soil erosion events in catchments, ....Mitigating extreme water supply contamination in bushfire burned catchments. This project involves Melbourne Water, the Department of Environment and Primary Industries, and East Gippsland Water in developing tools to evaluate mitigation options that will protect our water supplies and increase the resilience of Australian communities to bushfire. Major bushfires in south-east Australia in 2003, 2007, 2009 and 2013 were followed by storms that triggered extreme soil erosion events in catchments, contaminating water supplies and damaging critical infrastructure. The capacity to mitigate the risk of interruption to the water supplies of our cities and towns in a more fire-prone future is currently limited by our knowledge of where, why, and how often these post-fire contamination events will occur. This project aims to address these knowledge gaps.Read moreRead less

A major upgrade is under-way to enhance the sensitivity of the 3000 square kilometre Pierre Auger Observatory in its search for the origin of the highest energy cosmic rays, the most energetic particles known in the Universe. This follows an unexpected Auger result that indicates a significant fraction of these cosmic rays are heavy nuclei. This project, assisting the upgrade, is expected to significantly improve the observatory's ability to identify the mass, and hence the electric charge, of the incoming cosmic rays, allowing astrophysical source directions to be identified for the low charge particles less affected by cosmic magnetic fields. The project will also contribute to the understanding of particle interactions at energies well beyond those explored at the Large Hadron Collider.Read moreRead less
