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 ...

Cost Effective Irrigation with Centre Pivot Irrigation Systems
There are certain factors that should be taken into consideration when choosing the best irrigation system for your specific requirements. Some of these factors include the type of crop you are watering, the size of the land which requires irrigation, where your water is coming from and how much labour the system requires to operate. Dragline irrigation or movable pipe systems require far more ...

Irrigation Systems 101: What you need to know
In the perfect scenario everyone could rely on rainwater for their farming practices, but this is not always the case. This is why employing the right choice from the different irrigation systems available is crucial for agricultural success. Irrigation systems are basically an artificial way to provide water to fertile soil for agricultural purposes. Crop irrigation is necessary to overcome ...

Digging deep for new irrigation methods
Irrigation is essential to increase food production. However, competing needs and increasing drought makes water for irrigation scarce. Therefore, new methods and strategies are continuously being tested by scientists to improve food production, accompanied by better water use efficiency. This article will examine how modern field tools are helping in this venture. Irrigation Methods According ...

A comparative history, from the 16th to 20th centuries, of irrigation water management in Spain, Mexico, Chile, Mendoza (Argentina) and Peru
This paper explores the long-term development of irrigation system management, and looks at the influence of legislation, irrigation system size, scalar stress and polarized land tenure in the existence and success of self-management. The case studies are drawn from regions of the former Spanish Empire. Hispanic America, between the 16th and early 19th centuries, as part of the Spanish Empire, ...

Assessment of the performance of participatory irrigation management in Antalya, Turkey
This study examined 29 irrigation organizations in the province of Antalya, Turkey. Sufficiency, efficiency, sustainability and producer satisfaction were used as criteria for the productivity of irrigation networks. Differences in the irrigation organizations were compared and analyzed using a number of performance indicators. It was found that the irrigation associations had an irrigation ...

Comparative advantage for the areas irrigated with underground blue water in North China Plain
North China Plain is one of the most important grain-producing areas in China. Because of unevenly distributed precipitation in this semi-arid area, crop production largely relies on underground blue water (UBW) to irrigate, overexploitation of which causes a lot of environmental problems. In this paper, we first defined the representative division of winter wheat irrigation water production ...

Optimization of water distribution for open-channel irrigation networks
Water distribution for open-channel irrigation networks is more and more complex due to increasing constraints on water resources and changing demand patterns, whereas the performance of such systems is expected to increase. In this regard, an optimization approach is developed in order to schedule a fair scenario of water distribution among different users, where water demand is formulated in ...

Distribution of moisture and salinity under deficit irrigation and irrigation water salinity in an alternative trickle irrigation system of tape
This study was performed to investigate the horizontal and vertical distribution of soil moisture and salinity using an alternative trickle irrigation system of drip tape. Four main treatments consisting of 100, 80, 70, and 60% of the plants’ water requirements and three sub-treatments of 2.1, 4.6, and 10.2 dS/m, were conducted. Following irrigation, the soil moisture and salinity ...

Irrigation demand modelling using the UKCP09 weather generator: lessons learned
The determination of irrigation demand is typically based on crop modelling using a long historic record of local daily weather data. However, there are rarely adequate weather station records near to given sites; often any local records cover a limited number of years, are incomplete, costly or are of poor quality. This paper examines whether version 1 of the UKCP09 weather generator can ...

CSE algorithm: ‘canal survey estimation’ to evaluate the flow rate extractions and hydraulic state in irrigation canals
One of the main problems in water management of irrigation systems is the control of the equitable distribution of water among different orifice offtakes. The difficulty of managing a canal is partly caused by the lack of knowledge of the canal state because the scheduled demand is often not fulfilled, since farmers extract more water than is scheduled and it is impossible for the watermaster ...

Lessons learned in the development of smallholder private irrigation for high-value crops in West Africa
The objective of this report is to identify and evaluate best practices in smallholder private irrigation in West Africa. The report is based on a comparative assessment of the smallholder private irrigation subsector in Burkina Faso, Mali, Niger, and Nigeria, which included a literature review, field visits, and workshops at both national and regional levels. The task lists for the assessment is ...

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 ...

Subsurface drip and overhead irrigation: a comparison of plant boll distribution in upland cotton
Although subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops, the effects of SSD on the distribution of bolls on cotton plants (Gossypium hirsutum L.) have not been thoroughly examined. The purpose of this study was to add to the current knowledge about the effects of SSD on cotton yield dynamics. Cultivar DP 488 BG/RR was grown in three studies ...
