Abstract/Contents: | "This paper presents a comparison of methods for calculating uniformity in landscape irrigation auditing. The focus of the paper is a the difference between the Christiansen Coefficient of Uniformity (CU) and the Distribution Uniformity of the Low Quarter (DULQ). For this analysis 236 individual station in 35 sports athletic fields were analyzed. For comparison purposes, the calculations from these same stations are presented using the Distribution Uniformity of the Lower Half (DULH) and the Coefficient of Variation (CV). For most landscapes, the CU method was found to produce higher efficiency values than the DULQ method. In some cases, the difference in efficiency between the two methods was as high as 20%." |
