Welcome to the February 2017 OptiSurface Newsletter.
The News Of The Month features a dryland field in Hungary. We also welcome our new partner who joined us this month.
The Design Of The Month shows the details of the Hungarian Dryland.
The Feature Of The Month explains the improvement of the Batter Breakline operation.

This 26-ha field in Hungary has several ponding areas covering about 10% of the total planting area as shown in the Existing Drainage Analysis below. The farmer wanted water to drain on the north boundary over two outlets.

Proposed Topography
Ponding was eliminated using OptiSurface 4Way and a ridge was added covering the east, south and west boundaries to make sure water drains to the northern outlets. Earthworks ended up at 183 m3/ha.

Feature Of The Month
Improved Breakline Operation for OSDv2.5
Overview: Batter Breakline operation allows the user to create the base and side banks for channels and levees with one simple step.
Displayed By:
Right click Breakline > Batter Breakline
Appearance:
Horizontal Offset Distance – offset distance from the center line (breakline) to create a flat base by inserting two new breaklines.
Slope Ratio (1v:h:) – insert the horizontal (factor) e.g. 1v:20h. ‘Up’ if breakline is below surface e.g. drain channel; ‘Down’ for levees. Slope to Nearest is best used for roads, which can be both below and above the surface.
Slope Direction – refers to the ‘Left’ or ‘Right’ of the center line, usually best to select ‘Both’.
Shoot Slope To – surface where the batters will be referenced.
Shot Interval – use 5m or 15ft.
Max Distance – maximum distance the batters will be shot from the center line or offset lines.
Example:
A landform design was already calculated with an Exclusion subzone and a breakline was added to create the center line. The elevation of the center line was edited using Edit Breakline Table to adjust the slope to -0.05% making sure it drains well.
Step 1. Re-triangulate Proposed Topography without Breaklines. Right click Proposed Topography under Project Explorer > Re-triangulate > Without Breaklines.
Step 2. Right click the center line (breakline) then select Batter Breakline.
Step 3. Batter Breakline dialog will appear as shown under Appearance above. Insert values then hit OK.
The center line (breakline) was offset by 7.5ft creating a flat base 15ft wide. The batters were created with 1:20 or 5% slope going up to the Proposed Topography with each point 15ft apart. See cross section below:
