Summary

Computer modelling methods can be used to predict the distribution of sedimentary facies deposited by alluvial processes. The method presented here calculates the most likely flow paths for fluid moving over modelled topographic surfaces. The floodplain topography evolves largely through tectonic activity, together with deposition and erosion. This presentation investigates the effects of changing fault plane dip, fault offset and fault orientation on the distribution of flow lines, and discusses the implications of the model results for the patterns of sedimentary facies deposited in areas of surface deformation.
