Problem

The problem areas can be clearly seen Drainage Analysis in Figure 2 below showing ponding areas about 2 acres each and about 1 foot ponding depth. There are also areas that's having erosion issues.

Solution

An OptiSurface 4Way was used to design the field. This lets water meander across the field and drain to the edges. Waterways were designed in to minimize the width of the cut area to drain out those ponding areas.

Videos

Here's a video from the client's contractor while shaping this 200-acre farm.

Watch the video at about 13:40 mark where he discuss how he tackled the waterway design.

Conclusion

Total earthworks ended up at 27 yd³/ac (51 m³/ha) which is very low compared to traditional methods. Creating shallow waterways is a very effective technique to eliminate ponding areas while still allowing traffic and machinery to pass through these areas without issues.
