Abstract

With the purpose of improving the accuracy of the average irrigation depth calculation, an expression is presented assuming linear variation of the depth between two following collectors, for the determination of the average depth of center pivot irrigation systems. It is concluded that the proposed expression should be used for the determination of the mean weighed depth for being conceptually more correct, although, in practice the values calculated by the proposed methodology are very close to those obtained with the traditional calculation method.
