TDWB-19-2-Surface-Processes

TDWB-19-2: Delta experiment performed in Tulane University Deep Water Basin. Experiment evolved under constant forcings of water (0.17 L/s), mean sediment (1.41 kg/hr), and long term sea-level rise rate (0.25 mm/hr). Experiment run time was 560 hrs. Experiment used a strongly cohesive sediment that had a wide grain size distribution with a median diameter of 65 microns. The experiment evolved with marsh proxy sediment deposition. The marsh proxy was EPK, a type of kaolinite clay, and was deposited on the delta top every two-hours at an average rate of 200 g/2-hr. Experiment performed to explore interaction of delta and marsh sedimentation and resulting stratigraphy with dry topography monitored every 2 hours of run time.
