Description |
|
Movie 1. Convergence |
Development of convergent stratal patterns through time. Corresponds to case 1. |
|
Movie 2. Onlap |
Development of onlap through time. Corresponds to case 2. |
|
Movie 3. Sinusoidal input no bypass |
Stratal patterns through time that result from a sinusoidal sediment input curve and constant subsidence, without sediment bypass. Corresponds to case 3. |
|
Movie 4. Sinusoidal input and bypass |
Stratal patterns through time that result from a sinusoidal sediment input curve and constant subsidence, with sediment bypass. Corresponds to case 4. |
|
Movie 5. Constant to sinusoidal input constant subsidence no bypass |
This movie illustrates the influence of sediment input variability on stratal patterns. Subsidence is kept constant while the sediment input curve changes from constant to sinusoidally varying. |
|
Movie 6. Constant to sinusoidal input constant subsidence and bypass |
Similar to movie #5, but with larger overall sediment input so that sediment bypass is present. |
|
Movie 7. Constant to out of phase sediment input |
Constant to sinusoidally varying sediment input, on a background of sinusoidally changing subsidence. Sediment input curve is out of phase with subsidence curve. |
|
Movie 8. Subsidence and sediment input phases |
If both sediment input and subsidence are changing through time, the stratal patterns will change as a function of the phase relationship between the two. |
|
Movie 9. Static spill and fill |
Two linked minibasins with static fill-andspill: there is no subsidence and basin relief exists in both basins at the beginning of simulation. Red lines represent times of bypass; blue lines are condensed sections. |
|
Movie 10. Dynamic fill and spill |
Two linked minibasins with dynamic filland-spill: subsidence is taking place during sedimentation in both basins; otherwise the parameters are the same as in movie #9. Red lines represent times of bypass; blue lines are condensed sections. |
