Summary by reach of aux spwy CAPITALIZED reaches - constructed exit channel lower case reaches - natural ground in inlet & exit !! – reach to compute exit velocity Verify input correct - any unrealistic short reach? Assume normal depth in aux spwy

Stability Analysis
24
Conditions at peak of Stability Design Hydrograph Input template form – results for 1 reach Enter auxiliary spillway coordinates - all reaches Velocity & effective stress –TR-60 –Ag. Handbook #667

Reach Surface Performance Erosion stressErosion stress Headcut formationHeadcut formation
26
Reach Surface Performance Auxiliary spillway integrity analysis – Freeboard Hydrograph (FBH) Single storm simulation runs – entered storm hydrograph Integrity analysis - iterative three phase model Phase 1- failure of the surface cover & formation of concentrated flow –Lists phase 1 failure time or –How close the reach is to failure
27
Reach Surface Performance Reach 5 –Stressed to 89% of predicted surface failure –Example 80 ft spillway width –60 ft spillway - surface failed & exposed weak material below. Reach 6 –downstream of exit – headcuts 1.7 hour after hydrograph peak Reach 7 –13% slope –Develops headcut 1.5 hr after spillway flow starts (~2 hours before hydrograph peak)

IDE CONCEPT Output viewing and interpretation
33
The profile we’re using here is a silty, highly erodible material at the surface, over a layer of sandstone, over a shale
34
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).
37
These files are all the same except each has a different width of auxiliary spillway width (from 45’ to 100’).
40
Specify Summary Fields
42
Select file and highlight it to view text and graphics.
43
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.
44
This plot shows clearly that there is a change in conditions occurring between bed widths of 70 and 60 feet.
45
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.
48
Another headcut has formed at the upper end of the exit channel and is working its way through the crest.

Zoom capabilities
52
Note change in graph scales from previous slide. Before zoom
56
Below we have selected output for the BW: 200’ spillway.
58
You can change summary fields.
59
Select the data fields to be displayed by rows on the summary table.
62
This shows output by row rather than by columns.
63
Note that the line must be highlighted to view graphs or text (buttons below). This data is displayed by columns rather than by rows.
68
Double clicking on the material to change brings up the color chart. Changing Colors
70
Changing colors
71
Select the color you want to change and what you want to change it to. Then add to custom colors.
73
Note the edit is available The find feature is available here but not for the output accessible from the schematic menu.
76
Help is available at each input screen
