Studies tracing sedimentary particles to their source, referred to by geologists as provenance studies, can play an important role in the hydrodynamic approach to interpreting the rock record. This methodology is superior to the entrenched uniformitarian time-stratigraphic method, which filters interpretation through its geologic column because it 1) resolves presuppositional contradictions between the column and biblical history and 2) provides a sounder empirical foundation for interpretation. Ultimately, the hydrodynamic method could yield 3-D models of the flow regime of the Flood, calibrated to abundant forensic sedimentologic data. Though such models are not presently realistic, the empirical work necessary to support them can be done by the collection of local flow regime information from crustal sediments. Any future model will require calibration to flow information, which must be derived from sedimentological data—such as provenance studies. Examples of such studies suggest interesting lines of inquiry into nonuniformitarian alternatives and demonstrate additional shortcomings of the time-stratigraphic approach.
