CHAPTER 4<br />
This <strong>management</strong> practice is primarily applicable <strong>to</strong> furrow <strong>irrigation</strong> systems where<br />
significant amounts of tail<strong>water</strong> are produced. However, it can apply <strong>to</strong> the <strong>management</strong><br />
of runoff from any type system. This method does not improve application efficiency or<br />
distribution uniformity, but it can improve the quality of the tail<strong>water</strong> entering other<br />
surface <strong>water</strong>s.<br />
SCS National Practice 410 addresses the design of what are also called grade<br />
stabilization structures.<br />
IP 5.01.08 - Install Buried Tail<strong>water</strong> Drops and Collection Pipes<br />
Objective<br />
Eliminate sedimentation from high velocity flows in tail<strong>water</strong> systems.<br />
Description<br />
This Practice consists of installing a buried pipe system at the end of a field <strong>to</strong> gather and<br />
direct tail<strong>water</strong> flows. The Practice can improve the quality of the tail<strong>water</strong> re-entering<br />
surface <strong>water</strong>s by reducing or eliminating erosion losses caused by open ditch tail<strong>water</strong><br />
collection systems. This method should be applied anytime the soils are erodible or when<br />
tail<strong>water</strong> velocities in open ditch systems increase the risk of soil erosion.
