  • 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, ...

  • Opportunities for saving and reallocating agricultural water to alleviate water scarcity

    As water scarcity worsens globally, there is growing interest in finding ways to reduce water consumption, and for reallocating water savings to other uses including environmental restoration. Because irrigated agriculture is responsible for more than 90% of all consumptive water use in water-scarce regions, much attention is being focused on opportunities to save water on irrigated farms. At ...

  • Social and biophysical impacts of watershed development programmes: experiences from a micro-watershed area in India

    Rainwater conservation and soil erosion prevention are vital for the economic and financial sustainability of dry land agriculture. An integrated watershed development programme is thus a means of achieving these goals. Presently, integrated watershed management is receiving worldwide recognition as an effective model for watershed planning. A watershed is considered the basic geographical ...

  • Effects of two different water sources used for irrigation on the soil geochemical properties and the quality of the Lohan guava (Psidium guajava L. Lohan)

    The effect of two different water sources (treated waste water and lake water) used for irrigation on the soil geochemical properties and the fruit quality parameters of the Lohan guava were studied. The fruits' physical attributes, physicochemical attributes, nutritional attributes, mineral content as well as consumers’ acceptance were evaluated. The properties of the different water sources ...

  • Impact of agricultural water reallocation on crop yield and revenue: a case study in China

    Our study area in the People's Victory Canal Irrigation District of Henan Province in China has been transferring agricultural water to the city for municipal use. This study starts with an examination of the impacts of irrigation frequency, irrigation water sources, and irrigation water supply performance on crop yield and net crop revenue, using data from a survey of 182 households in the ...

  • Discerning shifting irrigation practices from passive microwave radiometry over Punjab and Haryana

    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 ...

  • The response of phytoplankton and microlayer-adapted bacteria to monolayer application in a humic, eutrophic irrigation dam

    Repeat applications of artificial monolayers to farm irrigation dams to reduce evaporative loss may adversely affect water quality by enhancing populations of microlayer-adapted bacteria and blue-green algae. The microlayer, subsurface and water column of a 16 ha dam were monitored every two weeks for 18 months, to benchmark the seasonal dynamics of phytoplankton and microlayer-adapted ...

  • 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. ...

  • 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 ...

  • Irrigation water requirements for seed corn and coffee under potential climate change scenarios

    The impact of potential future climate change scenarios on the irrigation water requirements (IRRs) of two major agricultural crops (coffee and seed corn) in Hawai'i was studied using the Irrigation Management System (IManSys) model. In addition to IRRs calculations, IManSys calculates runoff, deep percolation, canopy interception, and effective rainfall based on plant growth parameters, site ...

  • Reflections on evolving water management institutions and institutional bricolage: a case of irrigation schemes in Iringa Rural and Kilombero districts, Tanzania

    Over the past 40+ years, evolution of water institutions responsible for allocation and distribution of water has been enormous. This paper analyzes the evolution of both formal and informal water management institutions and how they affect today's processes of allocating and distributing water in farmer-managed irrigation schemes (FMISs). It also assesses how farmers translate and modify ...

  • Numerical simulation of bare soil water and heat flow under an automated irrigation system

    Modern irrigation techniques use automated systems where irrigation schedules are controlled according to certain criteria. The objective of this study is to numerically estimate irrigation events, water content and temperature distributions, evaporation, drainage, and soil water under closed loop automated irrigation systems of a bare soil. The automated irrigation system is activated and ...

  • 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 ...

  • Designing a rainwater harvesting system for urban green roof irrigation

    Green roof systems have been suggested to ease the growing urban environmental problems resulting from rapid urbanization. However, the irrigation of green roofs heavily depends on using precious potable water and consequently generates negative environmental effects. Rainwater has been recommended to address this dilemma, but the design method has not been well developed. In this study, the ...

  • Prospects of desalination for irrigation water in the Sultanate of Oman

    The most limiting factor for the agricultural sector in the Sultanate of Oman is a lack of water, and security of supply in terms of both quantity and quality. Salinization of both soils and groundwater systems along the coastal strip of Al-Batinah has placed a substantial burden on farmers regarding crop selection and, therefore, farm profitability. Desalination of brackish and seawaters ...

  • Special features of drip-sprinkler irrigation technology

    Irrigation techniques and technology based on principle of regular accumulation of moisture in active layer (surface irrigation, regular sprinkler irrigation) are most common in science and in practice. More progressive is principle of non-stop water supply of plants and soil in conformity to their water consumption. Drip irrigation and impulse sprinkling are based on this principle. The main ...

  • Irrigation challenges in the sub-humid US Mid-South

    Irrigated area in the Mid-South USA continues to increase and now totals four million ha. Because of low available water holding capacities and shallow root-limiting layers in many soils, irrigation management is difficult. Water quality and water use efficiency impacts under irrigation are poorly understood, but comprehension is necessary if conversion from groundwater to surface water supplies ...
