Optimal design of channel cross-section is an important task in the hydraulic design of open channels. The traditional methods and models which neglect the frost heave are trial procedures and may result in failure of channels in design of irrigation channels. To improve the total cost, reliability and effectiveness, the model which is used in this study, is not only minimizing the cost of land acquisition but also the cost of concrete lining considering cost as the objective function. The constrained optimization model which considers values of thickness of channel concrete slab constraint simultaneously along with the objective of minimization of cost is propounded and solved using a recent global optimization technique, namely cat swarm optimization (CSO). The optimized channel section not only satisfies the optimal hydraulic cross-section but guarantees the safety and stability of the side walls so that both the amount of the concrete lining and the land acquisition are optimized. Finally, we take a main channel of Qinghe Irrigated Area of Farm 853 in Heilongjiang Province as a study area. The results obtained using the CSO approach are satisfaction and the method can be used for reliable design of artificial open channels. Furthermore, we compare the CSO algorithm with a genetic algorithm (GA) and the particle swarm optimization (PSO) to verify the effectiveness of the cat swarm algorithm in the channel section optimization.

Senix Water Level Sensors Drive Irrigation Automation Project
Australia’s Water Crisis Irrigation management is serious business in Australia especially within the Murray-Darling Basin, a 1,000,000 square kilometer watershed that is home to Australia’s most productive agricultural land. The basin’s 23 rivers have some of the lowest and most variable flows in theworld. A massive system of dams, lakes and canals stores water from mountain snowmelt and seasonal rains and distributes it to farms and communities throughout the growing season. The Murray-Dar...
Treating wastewater as a resource
A number of UK landfill operators are turning wastewater into a resource by utilising OTT monitoring and control systems to manage the irrigation of Willow crops (for renewable energy generation) with pre-treated effluent. BackgroundLeachate from landfill sites represents a significant potential environmental liability, extending long into the future after a landfill site has closed. Conventional treatment and disposal options involve biological treatment and consented discharge to either the wastewater treatment...

BBA Pumps irrigation pumps, an unseen hero of daily life
The Netherlands receives on average 800 mm of rain each year. This, you may feel is the reason why you relatively never see BBA irrigation pumps out in the field. But it is more likely due to the fact that the B series of irrigation pumps rarely sits idle. Due to their convenient mounting on a wheelbarrow frame they can be easily returned back to the barn as soon as the job is done. This B60-220self-priming irrigiation pump is therefore almost invisible through daily life. But the owner of this pump and the...
