Summary
Imaging, analysing and forecasting Australian hazards with satellites. This project aims to improve Australia’s ability to anticipate geophysical hazards. It will generate a new national capability in the use of satellite radar imagery to monitor and manage geohazards, benefiting all communities. By producing high-resolution maps of ground displacements, the project will assess the controls upon where and why these events occur, and whether they exhibit precursory behaviour.

It will generate a new national capability in the use of satellite radar imagery to monitor and manage geohazards, benefiting all communities. By producing high-resolution maps of ground displacements, the project will assess the controls upon where and why these events occur, and whether they exhibit precursory behaviour. This is the first step towards accurate hazard forecasting and in building Australia's capability for near-real-time geophysical hazard monitoring on a national scale. The outputs will impact upon future recommendations for national earthquake and landslide monitoring and deliver new tools to underpin regulation of resource extraction and inform construction codes.Read moreRead less
Geodetic determination of the amount and spatial-scale of land subsidence and/or uplift in Australia. Heights can change with time, although most users assume that they are static quantities. Geodetic techniques will be employed to produce a vertical velocity model to make time-varying heights consistent and also to correct sea level change estimates at tide-gauges installed on land, that is either sinking or rising.
Geodetic and hydrogeological investigations of groundwater abstraction from confined aquifers: elastic response, heights, and sea level change. Parts of Perth are subsiding by as much as 5 millimetres (mm) per year, thus accelerating sea level rise relative to the land from 3 mm per year to 8 mm per year. The subsidence is most likely due to increased groundwater abstraction. This project aims to extend subsidence mapping in time and space using satellite-borne synthetic aperture radar, calibrat ....Geodetic and hydrogeological investigations of groundwater abstraction from confined aquifers: elastic response, heights, and sea level change. Parts of Perth are subsiding by as much as 5 millimetres (mm) per year, thus accelerating sea level rise relative to the land from 3 mm per year to 8 mm per year. The subsidence is most likely due to increased groundwater abstraction. This project aims to extend subsidence mapping in time and space using satellite-borne synthetic aperture radar, calibrated by complementary geodetic techniques, and coupled with new hydrogeological inputs from the Western Australian Department of Water. The research aims to provide science-based information to planners and managers on coastal vulnerability and determine the land response to groundwater abstraction. This will also allow for the correction of sea level change measurements from tide gauges.Read moreRead less
