On of our biggest projects till now has been planning and installing a system of 24 giant lysimeters in a cocoa research farm. Due to climate changes cocoa plantations are struggling to adjust to the new conditions in the tropical areas. This lysimeter system was designed according to our clients needs, determined to find the best irrigation plan for cocoa plantations around the world. ...
The City of Carmel, Ind., has partnered with irrigation professionals to promote efficient water use and green best practices. In June 2008, a coalition of irrigation experts — including six contractors, a designer and two distributors — met with water department officials to discuss how best to educate residents about solutions to save water and money. Irrigation Association members ...
Agriculture is a major element for survival of the human race and of the economic system. 42 percent of the world’s laborers are employed in agriculture, making it by far the most common occupation. With agriculture using approximately 60 percent of available freshwater withdrawals, concerns continue to grow over farmers implementing water conservation practices. ...
While many farmers around the world rely on wastewater for their crops, the practice can be dangerous without proper treatment and management A recent study reveals that the amount of water originating from urban wastewater used for crop irrigation around the world is much higher than thought. For the first time, researchers decided to assess not only the direct use of wastewater for crop ...
Raymond Irrigation District (RID) measures the flow rate of water delivered to over 46,000 acres of irrigated land and 300 municipal and agricultural water users in Southern Alberta, Canada. Concrete Water Culverts Before Canal is in Operation Most of the RID’s flow monitoring applications are in open channels or partially filled culverts. For help with this submerged culvert ...
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 ...

Overexploitation of groundwater (GW) in the recent past is a well-known fact for the Punjab and Haryana region of India, as reported by several studies using satellite-based gravity anomaly from the Gravity Recovery and Climate Experiment mission and also by using observed data. This decline in GW has enforced the Punjab Preservation of Sub-Soil Water Act 2009, and resulted in change in rice ...
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 ...
Climate change will affect the water balance of irrigated agriculture. Therefore, farmers and irrigation managers should consider adapting to new scenarios. Changes in water demands in a Mexican irrigation district were studied using an irrigation-scheduling model. The impact on water demands of two potential adaptation actions, adjusting planting season and using longer-season varieties ...
This study employs the positive mathematical programming (PMP) approach to estimate groundwater derived demand for irrigation using a cross-sectional dataset of 200 predominantly groundwater irrigated farms from the Punjab province of Pakistan. First, we find that the PMP optimal solution uses less water than what is available (being extracted) in order to make farmers allocate all the ...
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) ...
Water, one of the most crucial inputs of irrigation, should be utilized judiciously to identify appropriate strategies for planning and management of irrigated farmland. The present study was conducted for the crop maize (Zea mays), grown mainly in the rabi-season (July–October), to evaluate the irrigation water requirements in the temperate region of Kashmir Valley, India during the ...
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 ...
Climate changes and continuous population growth increase water demands that will not be met by traditional water resources, like surface and ground water. To handle increased water demand, treated municipal wastewater is offered to farmers for agricultural irrigation. This study aimed to enhance the effluent quality from worn-out sewage treatment facilities in rural villages, retreat effluent ...
Their Challenge On the San Xavier Reservation near Tucson, Arizona, the Tohono O’odom Nation grows organic alfalfa for racing horses plus fruits and vegetables. Thanks to Singer Valve, San Xavier is home to a sophisticated flood irrigation system that consists of one 16” (400 mm) globe style and eight 16” angle style valves and five storage tanks each with its own control ...
Summerheights Golf Links in Cornwall, Ontario draws irrigation water from the South Raisin River. Flow rates in the river can become very low during dry periods so water extraction is regulated and monitored closely. Flowmeter is equipped with an optional 2-million point data logger which stores daily total, minimum and maximum flow rates. Rory MacLennan plugs a USB memory stick into the ...
Governments are developing policy to reallocate water to environmental uses in many of the world's major river basins developed for irrigation. These policies can place considerable pressure on the irrigation sector to adjust, and may be perceived to conflict with food security and rural development goals. This paper reviews the literature examining opportunities to reduce irrigation ...
