TDB-12-1: Fan-delta experiment performed in Tulane University Delta Basin. Experiment evolved under constant forcings of water (0.17 l/s), sediment (0.00017 l/s), and sea-level rise rate 0.25 (mm/hr). Experiment run time was 1285 hr. Experiment used a strongly cohesive sediment that had a wide grain size distribution with a median diameter of 65 microns. Experiment performed to explore autogenic sediment transport and stratigraphy with topography monitored every 1 hour of run time. Data here are presented and stored according to the sandsuet version 1.0.0 specification. The data are contained in the `tdb12-meta.nc` file. This archive contains the topographic data only. The original dataset also contained metadata in the form of a word document. That word document explains more clearly the different data types collected in this experiment, and is also enclosed here.
