IDE CONCEPTIDE CONCEPT

• Output viewing and interpretation

The profile we’re using here is a silty, highly erodible material at the surface, over a layer of sandstone, over a shale

we indicated that the spillway would be overexcavated a half-foot and backfilled with topsoil, so we have to tell the program what that material will be like (in place).

These files are all the same except each has a different width of auxiliary spillway width (from 45’ to 100’).

Specify Summary Fields

Select file and highlight it to view text and graphics.

What the summary table looks like depends on what variables you have selected. You can select from a list of some 45 input and output variables and order them as you wish.

This plot shows clearly that there is a change in conditions occurring between bed widths of 70 and 60 feet.

To understand what that “something” is, we need to look at the output in more detail. To do this, we click on a file (Democ) causing the line in the summary table associated with that line to be highlighted. In this case, the line associated with the 70 ft bed width has been highlighted.We then click on the button “View Graphics” to view the graphics associated with that line in the summary table.

Another headcut has formed at the upper end of the exit channel and is working its way through the crest.

Right Click for display information after a build.

Zoom capabilities

Note change in graph scales from previous slide.

Before zoom

Below we have selected output for the BW: 200’ spillway.

You can change summary fields.

Select the data fields to be displayed by rows on the summary table.

This shows output by row rather than by columns.

Note that the line must be highlighted to view graphs or text (buttons below). This data is displayed by columns rather than by rows.

Double clicking on the material to change brings up the color chart.

Changing colors

Select the color you want to change and what you want to change it to. Then add to custom colors.

Note the edit is available

The find feature is available here but not for the output accessible from the schematic menu.
