Algae control in irrigation case study
Reduction of aerobic bacteria and algae in irrigation reservoir Analyzed parameters After finalizing the test the following was observed: strong reduction in algae and aerobic bacteria concentration. This lower amount in micro-organism concentration, in the water leads to lower biochemical oxygen demand (BOD). This subsequently leads to the improvement of the quality of the potable water. This ...

A critical comparison of using a probabilistic weather generator versus a change factor approach; irrigation reservoir planning under climate change
In the UK, there is a growing interest in constructing on-farm irrigation reservoirs, however deciding the optimum reservoir capacity is not simple. There are two distinct approaches to generating the future daily weather datasets needed to calculate future irrigation need. The change factor approach perturbs the observed record using monthly change factors derived from downscaled climate ...

Climate projection ensemble as support to water management and irrigation in Nigeria
Hydrological modeling was used for projecting average annual water availability in Nigeria in the future, comparing a baseline (1976–2005) with a 30-year future (2036–2065) period, simulated under an ensemble of ten climate projections. Simulations converged in projecting by mid-century an increase in water flows for almost half of the country. Models agreed also in projecting ...

LG Sound, controlling algae in irrigation reservoirs
Algae growth in irrigation water can cause a serious problem. Algae in irrigation tanks can clog the entire irrigation system, such as the pumps, filters, drip-installation and sprinkler nozzles. Besides that the algae and their by-products can also be spread over the irrigated area. In addition, some types of fungi, also present in these waters, can be harmful for the plants grown. Typical ...

Macro–engineering Australia's Lake Eyre with imported seawater
The macro–engineering project proposal exploits technologies that have the potential to quickly enliven the arid region surrounding Lake Eyre. The plan is focused on biosaline agriculture. The distinctive macro–project components are: Lake Eyre is gradually filled to a higher level by controlling evaporation and by pumping seawater from the nearby ocean using cheap tensioned textile tubes. Most ...

Quantitative assessment of the impacts of irrigation on surface water fluxes in the Tarim River, China
Irrigation is a significant human activity that affects surface water fluxes in the Tarim River Basin. To quantitatively assess the irrigation impact of this activity on surface water fluxes in the Tarim River, a land surface hydrologic model was coupled with a modified irrigation scheme and a reservoir module and applied to simulate these fluxes. Modeling results indicate that the combined ...

Central Asian irrigation sector in a climate change context: some reflections
According to expert opinion, the Central Asian region is likely to experience climate-induced changes with the irrigation sector being the most vulnerable to any change. Climate change impacts are interconnected with land use and socio-economic changes, and many other processes of a human–environmental system. Assessment and adequate information sharing play a critical role in decision ...

Stochastic order-based optimal design of a surface reservoir–irrigation district system
This paper explores the effects of streamflow uncertainty and the type of stochastic order, which is used for comparing stochastic variables, on optimal design of a reservoir multi-crop irrigation district system. Four nonlinear mathematical programs with an economic objective function including deterministic, stochastic-EXP with expected value order, stochastic-SD with stochastic dominance ...

Development of a decision support system for small reservoir irrigation systems in rainfed and drought prone areas
An integrated computer program called Cropping System and Water Management Model (CSWM) with a three-step feature (expert system—simulation—optimization) was developed to address a range of decision support for rainfed farming, i.e. crop selection, scheduling and optimisation. The system was used for agricultural planning with emphasis on sustainable agriculture in the rainfed areas through the ...

Water efficiency of agricultural production in China: regional comparison from 1999 to 2002
We apply stochastic frontier analysis (SFA) techniques to a provincial level data set to measure technical and water efficiency in China's agricultural production from 1999 to 2002. The determinants of the efficiencies are identified together with the physical determinant structure of the irrigation factor, which refers to the water use per irrigated land area. The study yields the following ...

Large-scale irrigation - Understanding energy-water-food connections
Original story at MIT News An MIT team is providing new understanding of the growing interconnections among three critical resources: energy, water and food. The work focuses on Pakistan's Indus Basin, where irrigation water is increasingly pumped from underground, a practice that is intensifying a preexisting shortage of energy. Using new and existing data plus statistical models, the ...

Water reuse through subsurface drip irrigation systems
Water reuse in Hawaii has been primarily relegated to agricultural irrigation and irrigation of golf courses and other large landscaped areas. The continuing effort to conserve and preserve potable water resources emphasizes using alternative water sources for irrigation. Agriculture, golf courses, highways, parks, playgrounds and cemeteries are among the heaviest users of irrigation water due to ...
