The radar and seismic data were collected simultaneously to evaluate the usefulness of each method for shallow-water stratigraphic mapping. The data were used in preparation of a benthic map and for creation of a facies distribution map. The majority of the interpreted facies show sub-bottom deposition that formed in a relatively low energy environment.
Significant changes do occur over relatively short distances however.
This allows a GIS-based interpretation of the mapping of the spatial distribution of the facies and the recognition and differentiation of sedimentary regimes in the river.
