Tulane experiments on sediment supply cycle influence on delta dynamics & stratigraphy
Delta (TDB-16-3-S1) experiencing large magnitude, short period sediment supply
cycles. Video of laboratory experiment documenting evolution of channelized delta experiencing large magnitude and short
period sediment supply perturbations. While sediment supply is changing the experiment had constant feed rates of input water and a long term sea level rise trend
that mimics subsidence. Experiment shares identical boundary conditions as TDB-12, except for the sediment supply cycles. Digital video was collected from camera
above the basin. Images were taken every 15 minutes with input water dyed to aid identification
of flow field. Colored sediment represents coarsest 10% of input sediment distribution. More details of experiment can be found in manuscript: Toby, S.C., Duller, R.A., De Angelis, S., Straub, K.M., 2019, A stratigraphic framework

Delta (TDB-16-2) experiencing small magnitude, long period sediment supply
cycles. Video of laboratory experiment documenting evolution of channelized delta experiencing small magnitude and long
