Seasons Greetings! Welcome to the December 2017 OptiSurface Newsletter.

The News Of The Month features the new tool called OptiLine with the new version coming to you very soon.

The Design Of The Month demonstrates a complex OptiSurface 2Way design using Ridge, Valley, Exclusion zones and breaklines.

The Feature Of The Month shows how to use Exclusion subzones when designing with OS2Way.

Field that I helped do an optisurface design on 3 years ago! When we topo'd it there were massive washouts and water standing all over!

Design Of The Month
Solving Ponding Issues Due To Wheel Tracks
A client in Illinois was having major ponding issues in his field due to 'micro furrows' created by planters and wheel tracks.

Existing Topography

Existing Drainage Analysis

The Ponding Map calculated with 2 inches high micro furrows in east to west direction is shown below.

Proposed Topography

An OptiSurface 2Way design was generated for the field.  OptiSurface 2Way allows drainage to opposite directions through taildrains or cross drains. Ridges and valleys are added to direct water and define the high spots and low spots of the field.

Proposed Flow Paths

Water drains away from the red ridge subzones into the blue valley cross drains then exiting the field in the east boundary.

Proposed Cut/Fill Map

Earthworks ended up at 106 yd3/ac or only 4240 yd3 for the 40 acre field.

Feature Of The Month
Overview:  Points inside the subzone are not included in the landform design. OptiSurface treats this area as a boundary, therefore allows drainage into the subzone.

This can be used for infield drainage where instead of using valleys, Exclusion subzones are used. But a drainage channel should be drawn using breaklines to form the surface.


Example:

The design of the month shown above shows a design using OptiSurface 2Way. Ridge and Valley subzones were added to define the high spots and low spots of the field.

The valley subzones represent the infield drains and is recommended to be perpendicular (or approach a perpendicular) to the Main Slope direction.

In cases where the infield drain will be parallel to the Main Slope direction, an Exclusion zone can be used instead of a valley zone.

See below the initial landform design calculation.

There are no points inside the pink Exclusion subzone. A surface is generated inside only because of the adjacent points triangulating.

If you can't see any images here, click 'Display images..' in your email software.
The Valley subzones fall into the Exclusion Zone treating it as boundary.

If you can't see any images here, click 'Display images..' in your email software.
Then it's just a matter of adding the breakline as the center line of the drain then battering it up to create the drain channel.  See the long sections and cross sections below.
