“…The objective of a sprinkler irrigation system is to channel water to the farm efficiently and uniformly. Proper spacing of sprinkler heads is a key component of uniformity and leads to a more efficient system [18]. Studied by Iqbal et al, [19] emphasize that the water is more uniformly distributed in tunnel farms compared to open area by using micro sprinkler irrigation system.…”

The design and arrangement of sprinkler irrigation systems are presented and discussed in this paper. The design is based on a rotating sprinkler system to irrigate the field. Information is provided concerning the components of irrigation systems and the characteristics of the system that affect water application efficiency. The mathematical model is developed to account for water overlapping area throughout a fixed sprinkler system and to evaluate the number of sprinkler irrigation for the whole field using water projection profiles from the experimental data analysis. As a result, a set of recommendations for the design of sprinkler irrigation system management are obtained. Finally, this problem is alleviated using the Maplet interface. By simply typing information in the text boxes and using drop-down menus in Maplet windows, the characteristic of sprinkler irrigation systems can be studied with relative ease.

In El Oued, southern Algeria, the traditional Mini-Centre Pivot System (MCPS) is widely used for the irrigation of agricultural crops, and its use has been growing continuously. However, these systems have a constant nozzle diameter along the lateral pipe, which affects productivity directly, besides decreasing both the quantity and quality of agricultural products by irrigation heterogeneity. Therefore, optimising the design of the MCPS nozzles is linked strongly to the desired uniform irrigation. This study aims to determine the optimal configuration of nozzles for high irrigation uniformity. To achieve this goal, a genetic algorithm was used for maximising the uniformity of MCPS-mediated irrigation. The optimisation is carried out according to water distribution modelling, calculation of the Heermann and Hein uniformity coefficient (CUH), and existing nozzle diameters. To verify the accuracy of the proposed model, three existing MCPS (60 m, 50 m, and 46 m in length) are investigated experimentally. The developed code findings in terms of CUH are in agreement with those obtained by experimental tests. The analysis indicated that the nozzle diameter should vary from 5 to 15 mm along the lateral pipe. In these optimal conditions, the CUH was improved by 29.77%, 33.99%, and 19.36%, respectively, for the existing 60, 50, and 46 m irrigation systems. The most obvious findings to emerge from this study is that using a genetic algorithm to optimise the design based on the nozzle size improves water application uniformity by more than 19% in terms of the CUH.
