Appearance:
- Boundary - select the boundary where the ditch network design will be calculated within.
- Topography - select the topography which will be the input to the calculation.
- Calculation Grid Spacing (m or ft) - define how far apart the calculation grid points are.
- Highest Elevation (m or ft) - define the elevation where the highest levee will be placed. Select 'Pick' to click the location on the Map.
-
Vertical Interval (m or ft) - define the vertical spacing of the levees.
-
Lowest Elevation (m or ft) - define the elevation where the lowest levee will be placed. Select 'Pick' to click the location on the Map.
- OptiLevee Technology - tick ON to optimize levee placement by maximizing spacing uniformity
- Vertical Tolerance (m or ft): define the amount of elevation difference of the contour bank and the selected boundary. - Delete Previously Created Breaklines - tick this ON to delete the breaklines created from the previous calculation.
Example:
This field will be designed for ponded rice. The field was smoothed with OptiSurface 4Way as shown below.
