  • 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 ...

  • 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 time ...

  • Novel simulation-based algorithms for optimal open-loop and closed-loop scheduling of deficit irrigation systems

    The scarcity of water compared with the abundance of land constitutes the main drawback within agricultural production. Besides the improvement of irrigation techniques a task of primary importance is solving the problem of intra-seasonal irrigation scheduling under limited seasonal water supply. An efficient scheduling algorithm has to take into account the crops' response to water stress at ...

  • Effects of treated municipal wastewater on fluctuation trend of leaf area index and quality of maize (Zea mays)

    The effect of primary-treated municipal wastewater (TMWW) on the leaf area index (LAI) and quality of maize (Zea mays) was studied in comparison to the clean irrigation water (control). The experiment was based on a randomized block design with four replicates, and it was conducted in a field experiment in Aligoudarz (Iran). Irrigation was applied with five different methods as treatments: ...

  • Omaha beach golf course

    The rich green swathes of the new extension of Omaha Golf Course are visual proof of high technol¬ogy at its best, enabling lush ungated grass to survive all year round despite being bordered on two sides by ocean and estuary and buitt on a combination of sand dunes and wetlands. It is a world first, and an international success story for the three main players - local drainlayer Ivor Jones, ...

  • Multi-temporal variation in water consumption of summer maize as determined by the Water Transformation Dynamical Processes Experimental Device

    A better understanding of the multi-temporal variation in evapotranspiration (ET) at different crop growth stages is the key for determining a reasonable irrigation schedule. In this study, a new device known as ‘Water Transformation Dynamical Processes Experimental Device’ (WTDPED) was used to monitor ET for maize under controlled environmental and groundwater conditions, and the ...

  • Worst Water Weeds #1: Hydrilla

    The Center for Invasive Species and Ecosystem Health lists a total of 79 different invasive and exotic aquatic plants that can be found in various parts of the United States. Some are wreaking more havoc than others, but one of the worst of all is hydrilla. It has invaded across much of the southern United States, and is beginning to make its way northward. Below are the basics of this invasive ...

  • How Much Will it Cost to Save Our Economy’s Foundation?

    During the past two summers, Pakistan was hit with catastrophic floods. The record flooding in the late summer of 2010 was the most devastating natural disaster in Pakistan’s history. The media coverage reported torrential rains as the cause, but there is much more to the story. When Pakistan was created in 1947, some 30 percent of the landscape was covered by forests. Now it is 4 percent. ...

  • Using coir as a growing susbstrate - sustainably and ethically

    Manufactured from the inner husk of coconuts, coir is, but its very nature, produced in distant, and often developing, countries. This means that there is also an ethical slant to consider, as well as the question of shipping costs and carbon use. As retailers apply more pressure on their suppliers to focus on sustainability and ethics, these points are becoming increasingly important. Growers ...

    Sector Consultation The Ontario Fruit and Vegetable Growers Association partnered with Vineland to host a research strategy workshop in November 2014 with the goal of defining the top five research priorities for each crop group. Grower organizations were invited to nominate two representatives to participate on their behalf and a number of researchers from relevant fields were invited to ...

  • Planting trees and managing soils to sequester carbon

    As of 2007, the shrinking forests in the tropical regions were releasing 2.2 billion tons of carbon per year. Meanwhile, expanding forests in the temperate regions were absorbing 0.7 billion tons of carbon annually. On balance, a net of some 1.5 billion tons of carbon were being released into the atmosphere each year, contributing to global warming. The tropical deforestation in Asia is driven ...

  • Soil and water: towards a larger-scale perspective of their relations

    Land use changes over time have altered relations between soils and water cycles throughout Europe. There are regions where forests were cut for agriculture or herding, or for industrial, mining, and/or railroad use. Soils were lost, through mud floods, and the water cycles changed so that their present status is one of badlands and/or desert-like areas. Early stages in the path to degradation ...
