Abstract

Post-Flood geomorphology was greatly affected by factors such as the connate water content of sediments, degree of lithification, volcanic activity, seismic activity, tectonic activity, precipitation, lack of vegetation, and various glacial processes. These factors and others greatly enhanced the potential for various types of erosion and mass wasting following Floodwater withdrawal from the continents on scales from minutes to millennia. Creation geologists have yet to realize the impact these processes could have played in shaping our present-day landscape; in geomorphic models proposed thus far, shaping happened by direct retreat and erosion of the Flood water itself. During the immediate post-Flood times (irrespective of where one places the Flood/post-Flood boundary) these factors would have contributed to immense continental denudation (and deposition), destroying (or burying) surfaces eroded during Floodwater retreat. The implications of these factors need to be included in post-Flood modeling and the development of young earth geomorphology models. While the focus of this paper is on denudation processes, insights into these processes will help us to better understand post-Flood depositional processes and the potential sediment sources and mechanisms for filling deep post-Flood basins, deposition of giant deltas and the formation of thick post-Flood blankets of sediment on the seafloor, for example.
