FIGURE 4-3. Depiction of an <strong>irrigation</strong> sufficiently <strong>water</strong>ing the entire field with good distribution uniformity<br />
and application efficiency<br />
Figure 4-4 depicts an <strong>irrigation</strong> with the same high distribution uniformity (same flat infiltrated<br />
<strong>water</strong>). However, twice as much <strong>water</strong> as needed was applied, resulting in a low application<br />
efficiency. Another practical example of this situation is the farmer who is using a well-designed<br />
and maintained micro-<strong>irrigation</strong> system. The hardware provides good distribution uniformity and<br />
the potential for high application efficiency. But, if the farmer runs the system twice as long as<br />
necessary, that potential is not realized.<br />
