Bed Top Profile

The Bed Top Profile function provides a 2D plot of a vertical slice through the model showing the water column and the sediment bed.

Figure 1 provides an example for the Pa Vinh (Son La Province, Vietnam) dam’s tailwater sediment transport analysis.  Each bar represents a model cell.  The thicker top bar represents the water column concentrations of total suspended solids (TSS) and the bottom, horizontally grouped, bars represent the sediment bed.
The height of the water column bar represents the water depth. The color of the water column bar represents the TSS concentration of the cell at the time shown in the legend. The color range corresponds to the TSS values shown on the key, above the color bar.

The height of the sediment bars represent the thickness of the upper most sediment layer that is interacting with the water column. There is a separate sediment bar for each grain size class being simulated. The color range corresponds to the mass fraction shown on the key, below the color bar. If the cell contains no sediments in a given class, that class' bar is not filled. The sediment class grain size is labeled in the key for each sediment bar.

RMC'ing on the legend or pressing the toolbar legend button will provide access to adjustments to the plot settings.
