Backslope Topography

The Backslope Topography defines the terrain elevation profile behind a wall segment. Each wall segment should have its backslope topography defined. By default it is set to a flat, infinite terrain.

Terrain profile

The following options are available:

• Infinite
• Broken
• User-defined

Infinite

Slope Angle: Defines a constant slope angle behind the wall (input zero degrees for a flat profile)

Broken

You define a broken backslope using the following parameters:

• x1: the distance behind the wall before the slope starts.
• x2: the horizontal run of the slope.
• Defined by slope angle: input an angle for the slope.
• Defined by y1: input a vertical rise for the slope instead of an angle.

User-defined

You can define a user-defined topography using the table whereby X is the horizontal distance behind the top of the wall and Y is the vertical height above the top of the wall.

Note that the X values must be entered in ascending order.

Apply to

• All segments in the current wall
• Current segment only (Section 1)
  

Use this to apply the current setting to either all wall segments in the current wall or the currently selected segment.
