Current study was carried out with aim to evaluate the effect of pressurized irrigation methods and furrow irrigation method with municipal effluent on distribution of salinity and moisture in the soil profile. The experimental study was designed by split plot layout with three irrigation methods including furrow, surface drip (SD) irrigation and subsurface drip irrigation (SSD) and two water q...

The layout of irrigation water distribution networks is usually branched. In most of the previous studies pipe sizes of the network had been optimized assuming a predetermined layout of the distribution system. However, only few researches have focused on the simultaneous layout and pipe size optimization. In this study a hybrid approach is adapted for simultaneous layout and pipe size optimiza...

the current study was carried out with the aim of evaluating the effects of pressurized and furrow irrigation methods on the distribution of salinity and moisture in the soil profile. the experimental study design was a split plot layout with three irrigation method including furrow, surface drip (sd) and subsurface drip irrigation (ssd) using two water qualities, municipal effluent (0.509 ds/m...

Climate change has brought increased temperatures and decreased rainfall on a global scale; however, population growth requires greater volumes of water food each year that must be supplied in one way or another. In Mexico, application efficiencies gravity irrigation are below 50%. Although recent years the decision been made to pressurized systems increase efficiency use, border furrow is stil...

Although the term precision irrigation is now quite widely used, often to mean drip irrigation, there is no commonly accepted definition or conceptualisation of the term, and no cohesive framework to guide research, development or adoption. This paper is reporting on a review of precision irrigation funded by NPSI. This review is considering the role of current irrigation application technologi...

The paper deals with calibration of the simulation models of hydraulic part of an irrigation project. Calibrated simulation model can be used in design, reconstruction, enlargement or maintenance of the pressurized irrigation systems. Computer model of the water distribution system is a valuable tool which can assist engineers and planners in analyzing the hydraulic performance of water deliver...

Background. The aim of this study was to evaluate the preliminary results of a new dissection technique in acute cholecystitis. Material and Method. One hundred and forty-nine consecutive patients with acute cholecystitis were operated on with continuous pressurized irrigation and dissection technique. The diagnosis of acute cholecystitis was based on clinical, laboratory, and radiological evid...

Abstract Filtering is an important measure for the prevention of emitter clogging in micro-irrigation systems. Head loss and energy consumption are two problems pressurized irrigation Therefore, a combined filtration device – micro-pressure filtering washing tank was designed. In this study, taken as research object, physical model test inlet flow sediment concentration carried out. The head pr...
