Wheel Tracks

OptiSurface Newsletter – 2016 Apr

Welcome to the fourth OptiSurface Newsletter.
Our News of the Month has a good story from the Corn & Soybean Digest which featured OptiSurface.  Plus a nice blog post where we show how wheel tracks can create ponding problems including a UAV video and drainage analysis.

The Design Of The Month is a vegetable farm which had drainage problems and short rows. Optisurface filled in some annoying ditches and got the field to drain nicely including tail drains.

The Feature Of The Month explains how to design ‘tail drains’ (drains at bottom of field) using ‘Subzones’.

Scroll down below for all the details. If you can’t see any images below, click ‘Display images below’ or similar in your email software.

Anytime, if you have any suggestions or problems, feel free to reply to this email or call me on +61 405-686-425 (Australia) or Preston on +1 870-340-2020 (USA).

Design Of The Month

OptiSurface 1Way with Taildrains
This field grows vegetables with pivot irrigation and raised beds running down the page.
OptiSurface 1Way was used to remove depression areas that cause ponding and fill the ditch that ran along the center of the farm allowing the field to drain from East to West (top to bottom of image).

Existing Topography
Proposed Topography
Subzones (green) were used to balance each pivot section of the field with the Balance Earthworks ticked ON and Cut to Export and Fill to Import defined as zero.

Another set of subzones (blue) were added to create the taildrains. Cross slopes were ticked ON and defined to force water to drain to a specific direction (in this case to the left or to the right) and drain into existing outlets. This is explained below in the Feature Of The Month.

Feature Of The Month

Taildrains using Subzones
Taildrains can be added in the design using normal subzones with defined cross slopes.  The direction where it falls can be determined by referring to the Main Slope direction or Main Slope Arrow.
Click image below to enlarge.
Main Slope Arrow:  Indicates the direction of the Main Slope.

Cross Slopes: It always refer to the main slope direction, falling to the east are positive (+) cross slopes while falling to the west are negative (-) cross slopes.

If you wish to force the slope of the taildrain to the east of the direction of the Main Slope, use two positive numbers for the Min and Max Cross Slopes e.g. Min: 0.05% and Max: 1.00%

On the other hand, if you wish to force the slope of the taildrain to the west of the direction of the Main Slope, use two negative numbers for the Min and Max Cross Slopes e.g. Min: -1.00% and Max: -0.05%
