What is SedPro - Stratigraphic Forward Modelling?

SedPro is a three-dimensional stratigraphic forward modelling software that allows a variety of inter-dependent surface and basin-forming processes to be studied at both geological and engineering time scales.

The results reflect possible changes in sediment distribution over time as a function of the depositional environment. sedPro can predict sediment distribution in a range of depositional environments and at scales from metres to several kilometres. The derivation of input data for such computer models should be no more onerous than that required for a conceptual geological model of an area. However, the need for quantitative data forces the geologist to a greater degree of commitment than may otherwise be the case.

SedPro is a three-dimensional stratigraphic forward modelling program based on the SedSim program developed originally at Stanford University in the 1980's and modified and extended in CSIRO until 2014.

SedPro consists of a series of computer programs that can be linked together or run separately. The core modules include:

• hydrodynamic,
• sedimentation,
• subsidence,
• sea level change,
• wave transport,
• compaction,
• slope failure and
• carbonates.

The program models sediment erosion, transport, and deposition, and predicts clastic and carbonate sediment distribution on a given bathymetric surface.

SedPro is controlled by a parameter input file, and files describing relative sea-level/base level change, water temperature, initial topography/bathymetry, and tectonic movement for each grid cell over time.
