Optimizing channel cross-section based on cat swarm optimization
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 ...

The costs of adaptation: changes in water availability and farmers’ responses in Punakha district, Bhutan
There is growing evidence that monsoon patterns are changing in the Himalayan region, which could potentially result in loss and damage for local farmers. To understand how farmers adapt to changes in water availability, we conducted a study in Punakha district, Bhutan, using qualitative and quantitative research tools. According to 91% of 273 respondents, water availability for rice irrigation ...

Colorado Irrigation Canal Channels - Case Study
Project Background “Different materials to protect canal liners had been tried in irrigation canals across the West over the past 15 or 20 years. One typical method uses a low cost earthen material like clay. Over time, however, these systems begin to crack and start to leak. It’s not a very efficient way to convey water,” notes Joe Kaul, Kaul Corporation, Presto ...

Optimization of water distribution for open-channel irrigation networks
Water distribution for open-channel irrigation networks is more and more complex due to increasing constraints on water resources and changing demand patterns, whereas the performance of such systems is expected to increase. In this regard, an optimization approach is developed in order to schedule a fair scenario of water distribution among different users, where water demand is formulated in ...

A computer model to estimate seepage rates from automated irrigation distribution channels during periods of shutdown
Within the last 10 years throughout south-eastern Australia, there has been a rapid expansion of modernisation efforts by irrigation companies that has included installation of automatic control structures, the so-called total channel control (TCC) technology. TCC includes supervisory control and data acquisition technology, which results in production of integrated databases utilising real ...

Delta Drainage and Irrigation System - Case Study
Background Delta, British Columbia is located in the Fraser River delta on the shores of the Pacific Ocean, just south of the City of Vancouver. Delta comprises mostly agricultural land, with typical ground elevations near sea level. Levees protect the area from potential floods from the Fraser River and tidal surges from the Pacific Ocean. Of the 13,500 hectares (ha) watershed, 6,300 ha is ...
