  • 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 ...

  • Study on the joint probability distribution of irrigation water volume and irrigation water efficiency

    Using the copula method, the joint probability distribution of irrigation water volume and efficiency is constructed, and their joint return period is also described to reveal the encounter probability of irrigation water volume and efficiency. Furthermore, the conditional probability of irrigation water efficiency with different water volumes is built to show the quantitative effects of flow on ...

  • A farm irrigation pond contaminated with diesel case study

    Due to a broken supply line a Yorkshire farm had a diesel oil spillage of approximately 1300 litres which contaminated the adjacent soil and the farm irrigation lagoon. Scientific Environmental Technologies (SET) were commissioned by the loss adjusters to bioremediate the contaminated site. SET chose Amnite P100 hydrocarbon degrading bacteria as the biological agent to break down the diesel oil. ...

  • Corn cob characteristics in irrigated central great plains studies

    Escalating fossil fuel cost and concern over global climate change have accelerated interest in cellulosic feedstocks, such as corn (Zea mays L.) cobs, for liquid fuel production. Little information is available about this plant organ. We compiled and summarized available cob data from several recent field studies in the Central Great Plains. Data were collected from two locations in Colorado and ...

  • Lindsay Irrigation advances VFD Pump Control case Study

    Put more"UMP" in your pump with VFD control Like most farmers, third-generation Nebraska corn grower Brian Wall is constantly looking for ways to make his farming operation more efficient and profitable. One of the ways he is doing that is by using variable frequency drive (VFD) control technology. Wall recently installed a Lindsay Watertronics VFD control panel on his 100 horsepower irrigation ...

  • Lg Sonic Ultrasonic Algae and biofilm control for irrigation case study

    Water used for irrigation can contain high levels of nutrients, some of these nutrients are beneficial for the plants watered, but can also lead to extensive algal growth. Algae in irrigation tanks can clog the irrigation system and can also be spread over the irrigated area. In addition, some types of fungus, also present in these waters, can be harmful for the plants grown. Therefore the ...

  • Estimating the ratio of pond size to irrigated soybean land in Mississippi: a case study

    Although more on-farm storage ponds have been constructed in recent years to mitigate groundwater resources depletion in Mississippi, little effort has been devoted to estimating the ratio of on-farm water storage pond size to irrigated crop land based on pond metrics and its hydrogeological conditions. In this study, two simulation scenarios were chosen to determine such a ratio as well as to ...

  • Group decision-making in land evaluation for irrigation: a case study from Serbia

    Presented in this paper is a methodology for a spatially based multi-criteria evaluation of land suitability for irrigation (IR). A group of experts use the analytic hierarchy process (AHP) and the consensus convergence model (CCM) to define weights of factors relevant in validating areas of land as suitable for IR and to develop IR suitability maps in the geographic information system (GIS) ...

  • Decision support system for irrigation maintenance in Indonesia: a multi-objective optimization study

    Maintenance of irrigation infrastructure is essential to sustain food production and farmers' earnings. Given the shortage of funds for maintenance in developing countries, it is critical to understand the degradation of the function of irrigation systems so that optimal budget allocations can be made. A case study of Indonesia proposes an Infrastructure Density Index that can be used to justify ...

  • Institutional analysis of irrigation management in Haiti: a case study of three farmer managed schemes

    In the late 1990s, like many other developing countries, Haiti started a process of devolving responsibilities over irrigation scheme management to water users’ associations. In this paper, a three-step methodology for institutional analysis is applied to investigate the functioning of this new setting in Haiti, using three irrigation schemes managed by farmers as case studies. First, the ...
