Numerical methods have been proved to be useful tools for understanding different phenomena. In this paper, triggered furrow irrigation has been analyzed by means of numerical modeling. To this end, a special code is developed for simulation of triggered furrow irrigation system by coupling three-dimensional Richards’ equation and one-dimensional fully hydrodynamic form of Saint-Venant equations. The

Anti-clogging performance optimization for dentiform labyrinth emitters Irrig. Sci. (IF 3.014) Pub Date : 2020-03-07 Bin Yang; Jiandong Wang; Yanqun Zhang; Haitao Wang; Xiaopeng Ma; Yan Mo
It is of great scientific significance to reveal the flow characteristics of dentiform emitters and to optimize the channel structure of emitters to improve the anti-clogging properties of emitters, which contribute to improving the working performance of irrigation systems. The study was carried out using computational fluid dynamics (CFD) simulations, combined with the physical test in the laboratory

Photosynthesis, growth, and water use of Hydrangea paniculata ‘Silver Dollar’ using a physiological-based or a substrate physical properties-based irrigation schedule and a biochar substrate amendment Irrig. Sci. (IF 3.014) Pub Date : 2020-03-07 Nastaran Basiri Jahromi; Amy Fulcher; Forbes Walker; James Altland
Developing management practices that make more efficient use of irrigation is important for improving the sustainability of nursery crop production. Integrating refined irrigation scheduling with a substrate amendment like biochar can improve irrigation efficiency. The objective of this research was to evaluate the impact of biochar and need-based irrigation scheduling on gas exchange, plant water

Development of optimal irrigation schedules and crop water production function for cassava: study over three major growing areas in India Irrig. Sci. (IF 3.014) Pub Date : 2020-03-06 Raji Pushpalatha; Sunitha Sarojini Amma; James George; Shiny Rajan; Byju Gangadharan
A study was conducted to develop optimal irrigation schedules and crop water production function for cassava in the three major growing areas of India, viz., Salem (Tamil Nadu), Thiruvananthapuram (Kerala), and West Godavari (Andhra Pradesh). The irrigation schedules and water requirements were simulated using CROPWAT, and the model result was verified with field values in Thiruvananthapuram, one of

A smart capillary barrier-wick irrigation system for home gardens in arid zones Irrig. Sci. (IF 3.014) Pub Date : 2020-02-23 A. Al-Mayahi; S. Al-Ismaily; A. Al-Maktoumi; H. Al-Busaidi; A. Kacimov; R. Janke; J. Bouma; J. Šimůnek
New water-conserving irrigation technologies are vital in arid countries. We investigated the effects of (i) soil substrates made of Smart Capillary Barrier Wick (SCB-W), consisting of silt loam blocks surrounded by sand-sheathes and irrigated with a sand wick cylinder (WC) as compared to a control (homogenous soil irrigated by the same wick system, HW), (ii) WC diameters (2.54 cm vs. 1.27 cm), and

Determination of soil hydraulic properties and its implications for mechanistic simulations and irrigation management Irrig. Sci. (IF 3.014) Pub Date : 2020-02-11 Alisson Jadavi Pereira da Silva; Everton Alves Rodrigues Pinheiro; Quirijn de Jong van Lier
Water retention θ(h) and hydraulic conductivity K(h) are mandatory soil hydraulic properties (SHP) for consistent hydrological modeling and for an efficient irrigation management. Most commonly, SHP are determined by conventional methods (CM), based on hydrostatic equilibrium and the independent measurement of saturated hydraulic conductivity, which is used as a matching point for K(h) function. Alternatively

Use of the Luus–Jaakola optimization method to minimize water and energy consumption in scheduling irrigation with center pivot systems Irrig. Sci. (IF 3.014) Pub Date : 2020-01-25 Kennedy M. Fernandes; Roberto A. Tenenbaum; Edwin B. M. Meza; João Batista L. da Silva; Diego N. Brandão
This paper proposes a new methodology for solving the scheduling problem of center pivot system irrigation timetable based on the Luus–Jaakola optimization method. The new methodology considers as influencing factors the water and energy consumed and the limit of the available flow to the areas that are being irrigated. The methodology allows the implementation of a non-linear model during an acceptable

Assessing the impact of water-saving technologies on Boro rice farming in Bangladesh: economic and environmental perspective Irrig. Sci. (IF 3.014) Pub Date : 2020-01-14 Md. Taj Uddin; Aurup Ratan Dhar
The study was conducted to evaluate the economic and environmental impacts of water-saving technologies (WST) on Boro rice (Oryza sativa; var. BRRIdhan 29) farming in Bangladesh. A total of 480 farmers (80 focal and 400 control) were selected as sample from Mymensingh, Comilla, Bogra and Gaibandha districts. Focal farmers were selected purposively and a limited amount of financial support was provided
