Basin Genesis Hub computer model explains Early Cretaceous eastward flow of ancient Murray River

24 January, 201725 January, 2017 by Carmen Braz

Australia is an outstanding natural laboratory to study the influence of dynamic topography on landscape evolution, having been largely unaffected by tectonic deformation since the Jurassic. Recent studies of the past eastern Australian landscape from present-day longitudinal river profiles and from mantle flow models suggest that the interaction of plate motion with mantle convection accounts for the two phases of large-scale uplift of the region since 120 Ma. … Read more…

Basin GENESIS Hub opening group photo 19 August 2015

The ARC Research Hub for Basin Geodynamics and Evolution of Sedimentary Systems (Basin GENESIS Hub) opened today at a reception held in the Charles Perkins Centre at the University of Sydney. The launch as attended by representatives from Universities, industry, Geoscience Australia, the ARC, the NCI and the Office of the NSW Chief Scientist and Engineer.

The Basin GENESIS Hub will use computer modelling to fine-tune our understanding of the nation’s sedimentary basins, which hold many of the natural resources we use in day-to-day life.

The research will be of fundamental importance to the geo-software industry used by exploration and mining companies, explains Hub Director Professor Dietmar Müller from the University of Sydney. … Read more…

Basin and Landscape Dynamics (Badlands)

11 August, 201526 August, 2015 by Stephen

Basin and Landscape Dynamics (Badlands) is a parallel TIN-based landscape evolution model, built to simulate topography development at various space and time scales. The model is capable of simulating hillslope processes, fluvial incision (erosion/transport/deposition), spatially and temporally varying geodynamic (3D displacements) and climatic forces which can be used to simulate changes in base level, as … Read more…

High horizontal fault displacement rates and landscape evolution

11 August, 201526 August, 2015 by Stephen

In this numerical model of landscape evolution we impose over 2 million of years deformation produced with the Underworld software over an initial flat surface, ie a 256 km square box at a resolution of 1 km. On top of the deformed surface, a landscape evolution model, Badlands, is used to simulate both hillslope and … Read more…

The Basin GENESIS Hub

16 November, 20141 April, 2017 by Stephen

The ARC Research Hub for Basin Geodynamics and Evolution of Sedimentary Systems (Basin GENESIS Hub) is a showcase of connecting “Big Data” analysis and high-performance computing in an open innovation framework. The hub will fuse multidimensional data into 5D basin models (space and time, with uncertainty estimates) by coupling the evolution of mantle flow, crustal deformation, erosion and sedimentary processes using open-source modelling tools.

The project will develop quantitative, cutting edge data analysis techniques to underpin the testing of new concepts for understanding basin structures, and aid in driving sustainable use of basin resources. The development of new high-performance simulation and data mining tools, making use of new petascale computing capabilities, will connect big, multidimensional data sets to cutting edge machine learning and modelling algorithms to cross a wide spectrum of spatial and temporal scales. … Read more…
