Abstract

This study was conducted to evaluate the water application uniformity for a drip irrigation system, considering the water quality and the duration of usage. The uniformity parameters, Emission Uniformity (EU %) and Uniformity Coefficient (UC %) were determined for the drip irrigation system installed over a year of performance. The procedures are based on taking measurements of emitter discharge along selected driplines on a sub-main. The catch can be identified as L1A, L1B, L1C, L1D, same for L2A to L2D, L3A to L3D and L4A to L4D. This gave a total of sixteen (16) measurement positions as there were 4 driplines. Results indicated that the uniformity of water application was 90% indicating that the emitter was still good after a year of installation. The average discharge rate was 0.57 l/h. The uniformity coefficient (UC %) for the gravity-fed drip irrigation system was 78%, indicating good water application and was quite significant for the evaluation of the uniform distribution of water for the design. The expansion of this irrigation method in rural communities could contribute to relevant water savings in most areas of the Upper West Region of Ghana.

加纳上西部地区安装的小型滴灌系统的现场性能评估

在考虑水质和使用时间的情况下，对滴灌系统的施水均匀性进行了评价。确定了滴灌系统安装一年以上性能的均匀性参数、排放均匀性(EU %)和均匀性系数(UC %)。这些程序是基于沿着子干线上选定的管道测量发射极放电。捕获可以识别为L1A, L1B, L1C, L1D, L2A到L2D, L3A到L3D, L4A到L4D。总共有16(16)个测量位置，因为有4根绳。结果表明，灌水均匀性为90%，说明灌水器在安装一年后仍具有良好的性能。平均放电速率为0.57 l/h。重力式滴灌系统的均匀性系数(UC %)为78%，说明滴灌系统的施水量良好，对设计中水分均匀分布的评价具有重要意义。在农村社区推广这种灌溉方法可有助于在加纳上西部地区的大多数地区节约用水。
