Five stratigraphic units of the Triassic Beacon Supergroup at Mt Bastion were investigated to determine paleohydraulic river regimes. The study, conducted by SCIOPS, analyzed features of the sedimentary sequence to characterize the river system. Data was last updated in November 1981.
Use Cases
- Reconstruct paleo-river discharge from sedimentary channel width and depth measurements.
- Analyze changes in river sinuosity and slope across the five stratigraphic members (Fleming Member, Lashly A-D).
- Model the evolution of the Triassic alluvial plain using derived hydraulic parameters like channel geometry.
Strengths
- Analysis covers five distinct stratigraphic units within the Triassic sequence.
- Investigates multiple specific hydraulic parameters (sinuosity, width, depth, slope, discharge).
Limitations
- Dataset is from a single study site (Mt Bastion), limiting geographic generalizability.
- Data is from 1981 and may not reflect contemporary analytical methods or standards.
- Sample size (number of measurement points or rows) is unknown.
