“…Others focus on water-quantity management, addressing issues like water-demand management (Dziegielewski 2003) or water-supply management (Gerasidi et al 2003); and finally some authors look at a single measure in a particular sector (e.g. irrigation, desalination, wastewater reuse) for which technical options are compared (Machiwal et al 2004;Montero Martínez et al 2004;Gilau and Small 2008). This paper considers a holistic approach of cost-effective water-quantity management at the river-basin scale, considering water balance and both demandand supply-side management measures.…”

Chekka Bay area and Amman Zarqa Basin are two complex river basins in northern Lebanon and northern Jordan respectively. Both regions are faced with growing populations, urban development and land-use changes. They also both suffer from water-resource scarcity and contrasted seasons that threaten the perennity of sufficient water supply. Decision makers may have several water-management measures in response to the issue of water deficiency in their regions, but they need simple methods and criteria for ranking the alternatives with respect to their economical efficiency. In this paper, the Cost-Effectiveness Analysis method is used for supporting decisions to optimally combine water management measures at the river basin scale. Hydrologic and socio-economic data are used for assessing the future water balance and determine the sustainable management objectives. Both supplyand demand-side measures are investigated and compared. The analysis is based on two basic metrics to assess cost-effectiveness ratios: the average annualized and the marginal (or incremental) unit cost. The results show that the cost-effectiveness ranking of alternative measures strongly depends on the selected metric. The average annualized unit cost systematically favours large scaled water measures with high costs while the average incremental unit cost facilitates the selection of smaller and costless measures reflecting the time preference for water supply.

“…Meanwhile, reductions in the energy requirements of center pivot and lateral-move irrigation machines have successfully been achieved by replacing the traditional impact sprinklers with spray sprinklers [10]. Martínez et al [13] noted that reducing the operating pressure of the sprinkler and using low-pressure sprinklers can significantly decrease the operating cost. However, most of the studies on low-pressure sprinklers have been confined to fixed spray plate sprinklers (FSPSs) and rotating spray plate sprinklers (RSPSs) [14][15][16].…”

Using low-pressure sprinklers in agricultural irrigation has become an alternative way of reducing water and energy stress. To determine the applicability of the low-pressure rotating sprinkler, an experiment was conducted to evaluate the effects of working pressure and nozzle size on sprinkler rotation speed, application rate, droplet size, droplet velocity, droplet trajectory angle, and kinetic energy distribution. The results showed that the mean droplet diameter increased exponentially along with the increase in distance from the sprinkler, and a logarithmic relation was derived between droplet diameter and droplet velocity. Due to the low breakup degree of the jet under the lowest working pressure of 100 kPa, the peak values of specific power and application rate were high, which reached 0.09 W m−2 and 11.35 mm h−1, and were 3.1–5.4 times and 2.5–3.1 times those of other working conditions. Meanwhile, the peak specific power of the biggest nozzle (diameter = 5.2 mm) was 2.4–2.8 times that of smaller nozzles. With an increase in working pressure, the sprinkler time per rotation decreased and the distributions of kinetic energy and water became more uniform. Thus, it is not recommended to equip the sprinkler with a large nozzle under low working pressure.

“…As per the literature, some of the most significant influencing factors in terms of investment and cost, which imposes the highest amount on an irrigation system, include pipe diameter and length, as well as the number of sprinklers and laterals [15]. Various strategies and methods have been applied to reduce the system costs and provide the most cost-effective option for the farmers.…”

“…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%.
