There's a lot of dryland fields here that if you're gonna move 30-40,000 yd3 with laser and with OptiSurface you can move it with 10,000yd3 to irrigate it means a lot. - Bryan Thurman, Missouri, USA.

"After significant rainfall, I flew up in my plane and got some pictures. As far as you can see, ponds are gleaming in everybody's field. I looked into my field which I had just OptiSurfaced and there wasn't one pond standing on that field." Jeff Kelly, Illinois, United States

Design Of The Month
Solving Ponding and Runoff Problems in the Desert

The client is in Central Nevada and grow alfalfa and wheat under center pivots. He states his problem as:

"This particular field was never properly levelled (landformed) and the many low and high spots cause ponding and runoff issues as well as increased disease and pest pressures in the low/tight spots."

Watch the video below to get Graeme's explanation and see the images below.


This example plants alfalfa and winter wheat over a pivot. The field is planted without furrows and can drain to any direction as long as it goes out to the boundary. The design was straight forward - OptiSurface 4Way with 0.10% minimum slope and 1.0% maximum slope and 300ft/% smoothing.  The cross slope parameter, if ticked OFF, follows the set parameters on the Main Slope but can still be ticked ON and have it's own parameters.

Proposed Flow Paths

Feature Of The Month
Overview: OptiSurface 4Way is a Surface Type which can drain in any way (4Way) and meander across the field as long as it is continually falling to some location on the boundary. This suits crops grown WITHOUT furrows where the water can drain in any direction. All locations on the field have positive slope towards the boundary (i.e no depression areas to hold water). An example application is rainfed wheat where it is planted on a flat soil surface (no furrow) and water can drain in any direction. Note: it is called OptiSurface4Way because in actual fact the calculated surface falls in only 4 directions of the calculation grid (eg North, South, East or West or similar depending on grid rotation setting). This can produce jagged flow paths which can be smoothed using the slope smoothing (Slope max change) and breaklines.
