Abstract

The lower ends of most furrow irrigated fields have become
convex shaped, meaning the slope progressively increases
from a point 20 to 60 feet from the field end to the
tailwater ditch. This increasing slope is the result of maintaining
tailwater ditches too deep and keeping them cleaned
so runoff from these fields is not restricted. The process of
forming a convex field end continues yearly at an increasing
rate. With each passing year, the slope at the end of the
field becomes greater so that runoff water runs faster and
has more energy to erode. Over many years, large quantities
of soil have been lost from the lower ends of furrow
irrigated fields. Field ends 1.5 to 2.0 feet lower than the furrow
elevation 20 to 60 feet upslope are common. Much of
the soil loss is from the lower ends of fields.
