Defining Pond Slopes
Once you establish a pond perimeter, you can design the pond slopes in a
variety of ways.
n
You can apply single or multiple slopes or grades to the pond perimeter.
n
You can design the pond slopes based on a known required volume. This is
useful if you use the Detention Basin Storage command to compute the
required storage volume.
n
You can also design pond slopes with a template that represents the pond
bank. A pond slope template works similarly to a Civil Design roadway
template. You draw a cross-sectional view of the pond bank, save it to a file,
and then apply it to the pond.
Pond slope, elevation, and depth data is referred to as pattern data. Each pond
vertex stores its own pattern data. Pattern data is created when you use the
Pond Slope commands to design the slope of the pond bank. If you want to
remove the pond pattern data from one or more vertices on a pond, then you
can use the Reset Patterns command. You can also reset the patterns on selected
pond vertices when using the Linear-Multiple command.
NOTE
At the end of using the Pond Slopes commands (except the Linear 
Multiple command and the Template  Multiple command), you are
prompted to shape the pond. If you choose to shape the pond, then pond
contours, the pond bottom, and the pond slope control lines are created in
the drawing. A shaped pond is required for some of the Hydrology
commands. If you choose not to shape the pond at the end of a Pond
Slopes command, then you can use the commands in the Shape Pond
menu to shape the pond.
