Abstract

As a rule, in the practice of irrigation, more water is delivered to a project than is used by the plants, evaporated, or removed by natural drainage. It is now generally accepted that, in the West, irrigation and drainage are necessary complementary practices. With comparatively good irrigation practice the efficiency is about 34 percent; that is, approximately one-third or the water is actually used by the crops. With rather poor irrigation practice the efficiency may drop as low as 12 percent.
