Understanding the Deep Carbon Cycle from Icehouse to Greenhouse Climates

16 May, 20178 May, 2017 by Ruken

Sydney Research Excellence Initiative grant (2017-2018) Research area, key questions, significance, and innovation. The planet is experiencing a major transition from an icehouse climate, one dominated by permanent continental ice sheets at high latitudes, to a greenhouse climate that favours ice-free conditions. Although part of the deglaciation trend is influenced by a natural orbital cycle, … Read more…

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

25 January, 201724 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…

SoftwareX – Badlands: A parallel basin and landscape dynamics model

7 March, 20193 October, 2016 by Carmen Braz

Abstract: Over more than three decades, a number of numerical landscape evolution models (LEMs) have been developed to study the combined effects of climate, sea-level, tectonics and sediments on Earth surface dynamics. Most of them are written in efficient programming languages, but often cannot be used on parallel architectures. Here, I present a LEM which … Read more…

Surface Processes Modelling Workshop

26 September, 2016 by Carmen Braz

The EarthByte Group will conduct a 2 days workshop on surface processes modelling on the 13th and 14th of October in the Madsen Building at the School of Geoscience, The University of Sydney, Australia.

The workshop aims to introduce those interested in landscape evolution and source to sink problems to a new open-source code: Badlands. Note that you do not have to be a seasoned modeller to participate. Geomorphologists, tectonicists and sedimentologists interested in testing conceptual models based on field observations are welcome! … 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)

7 March, 201911 August, 2015 by Michael Chin

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

26 August, 201511 August, 2015 by Michael Chin

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…
