“…The optimal design of irrigation systems has largely concentrated on the economic cost of the system over its entire life span by taking into account capital and/or energy costs for a fixed area (Hussian et al, 2008; Kale et al, 2008; Mahar & Singh, 2014; Ortiz Romero et al, 2006; Singh & Mahar, 2003). This paper presents the development and application of a nonlinear programming model for the optimal design of the main line length and lateral lines by considering pump characteristics without throttling the pump.…”

An optimisation model is developed for designing a single‐ and two‐pipe size periodic‐move sprinkler lateral for various values of uniform upward and downward slopes. Two layouts are considered, and the optimisation model maximizes the length of the main line subject to a minimum desirable pump efficiency and an allowable pressure variation without throttling the pump at the lateral inlet. The step‐by‐step approach is used for computing the frictional head loss of the pipelines for analysis of sprinkler pressure heads. The head‐discharge characteristics of sprinkler heads, the pipe characteristics of the lateral and main lines and the pump characteristics are matched to determine the optimal diameter and length of the main line and diameter of the lateral line. The applicability of the optimisation models are illustrated by solving standard design problems using LINGO 18.0. Larger pipe diameters for single‐ and two‐pipe size laterals resulted in an increase in the length of the main line and, subsequently, the area. The developed optimisation model can be used for designing the periodic‐move sprinkler irrigation system for any given field and farmers conditions according to field shape, topography of the land and availability of sprinkler components, pipe sizes and pumps.

“…Various strategies and methods have been applied to reduce the system costs and provide the most cost-effective option for the farmers. Irrigation systems cost comparison has been done in many studies [15][16][17] to analyze and specify the highest expediency for the systems. Among them, portable and semi-permanent systems or set-move with removable laterals [18,19] are the two most profitable.…”

The experiment was done based on a new layout for a semi-permanent set-move sprinkler irrigation system with a lower capital and annual cost requirement. In this work, a center-pivot system layout was applied to set up a semi-permanent system with a hand-move lateral. The clock hand lateral (CHL) sprinkler irrigation system was implemented using a shorter mainline length with a smaller diameter, lesser number of lateral pipes, minimum number of fittings and a single valve outlet. This combination offers an affordable irrigation system with minimizing the required components. The new irrigation system design was examined at the Agricultural Academy of Science experiment farm at Guangxi, China. The sprinkler system mainline pipe directly extended from the water resource to the center of the plot to feed a single lateral, connected through a pivot elbow. The lateral was rotating around the plot manually, the same way as clock hands do. An ordinary set-move split lateral for the same plot was designed for comparison and control. Based on results, a 37.5% capital cost reduction with an 11.2% annual cost decrement was obtained for CHL compared to the set-move semi-permanent. Water application depth was measured via distribution uniformity coefficient (DU) examination, using a catch can method. The low quarter DU for CHL was counted for 86%.

“…Indeed, without government funds, in most regions small plot owners would not be able to afford pressurized irrigation. According to different economic studies on sprinkler irrigation systems [15][16][17], main/sub mainline length and dimension have a great influence on the system capital and annual costs requirements. Therefore, semi-permanent or portable systems have reduced the pipes and other components to offer a cost-effective option [18,19].…”

Sustainable Water Resources Using Corner Pivot Lateral, A Novel Sprinkler Irrigation System Layout for Small Scale Farms

et al. 2018

Sprinkler irrigation systems are widely used in medium and large scale farms in different forms. However less types are available to apply in small farms due to their high costs. The current study was done according to a novel cost effective design for a semi-permanent sprinkler irrigation system for small farm owners. The new layout known as Corner Pivot Lateral (CPL) was examined in irrigation test center at Lijian Scientific and Technological Demonstration Park, at Nanning city, China. CPL was implemented without a main/sub mainline pipe, by applying a single pivoting lateral at the corner of the plot that directly connected to the resource to convey water from the pump. The lateral moves around the corner using a rotating elbow in a quadrant pattern manually to cover the entire farm. A conventional semi-permanent system was applied for the same farm as reference. A cost analysis on the required components as well as annual operational costs was carried out for comparison and control. Results showed that a lower system component would be needed for the CPL method. Overall, more than a 15% capital cost reduction with 7% annual cost decrement was achieved for CPL in this experiment comparatively. The Catch can technique was applied to examine the CPL system’s efficiency and 79% water distribution uniformity around the sprinkler was obtained. This new method can encourage small estate holders to switch from traditional to pressurized systems which optimizes water application costs.
