A Numerical Model for Genesis Flood Processes

Despite false statements spread by their opponents, creationary scientists do research, publish in journals, and present models like their secular counterparts. Sometimes these are turned down by other scientists, and sometimes the scientists realize that something is amiss. Such is the case with this model for the Genesis Flood by Dr. John Baumgardner. Anti-creationists get on the prod when confronted with evidence and coherent models for the Genesis Flood, because that global event refutes many uniformitarian views and is strong evidence for a young earth.

Dr. Baumgardner had a "waitaminnit" moment when he realized that certain aspects of the previous version of his model, published in February 2016, did not work. There was a numerical issue that negated the paper he presented, so he commenced to doing some revision, and has presented this improved version. Note that it's rather technical, as you'll realize from the abstract, and people with a strong background in geology are more likely to fully appreciate it.

This paper describes a numerical model for investigating the large-scale erosion, transport, and sedimentation processes associated with the Genesis Flood. The model assumes that the dominant means for sediment transport during the Flood was by rapidly flowing turbulent water. Water motion is driven by large-amplitude tsunamis that are generated along subduction zone segments as the subducting plate and overriding plate, in a cyclic manner, lock and then suddenly release and slip rapidly past one another. While the two adjacent plates are locked, the sea bottom is dragged downward by the steadily sinking lithospheric slab beneath. When the plates unlock, the sea bottom rapidly rebounds, generating a large-amplitude tsunami. Theory for open-channel turbulent flow is applied to model the suspension, transport, and deposition of sediment. Cavitation is assumed to be the dominant erosional mechanism responsible for degradation of bedrock as well as for erosion of already deposited sediment. The model treats the water on the surface of the rotating earth in terms of a single vertical layer but with variable bottom height. Illustrative calculations show that with plausible parameter choices average erosion and sedimentation rates on the order of 9 m/day (0.38 m/hr) occur, sufficient within a 150-day interval during the Flood to account for some 70% of the Phanerozoic sediments that blanket the earth’s continental surfaces today.
