Effect of Channel Slope on discharge coefficient of Cylindrical Crested Weirs

Dec 6, 2012

Journal: Engineering and Technology Journal 31 (7)

Publisher: University of Technology, Iraq

DOI: https://doi.org/10.30684/etj.31.7A15

This research paper investigates the effect of the longitudinal channel slope on the discharge coefficient of cylindrical weirs. The methodology applied is by adopting three different diameters of the cylindrical weir and at three different slopes of the channel. In addition, various five flow rates values were used for each case. The study showed that the discharge coefficient increases when...
Pressure effect on wetting pattern in layered soil for subsurface point source

May 17, 2012

Journal: Al-Rafidain Engineering Journal 21 (2)

Publisher: Al-Rafidain Engineering Journal

DOI: 10.33899

Laboratory experiments were carried out to investigate the effect of operating pressure on wetting pattern in layered soil for subsurface point water source. This study helps to determine a suitable operating pressure and appropriate spacing between emitters and drip lateral pipes . The layered soil profiles were prepared using two types of soil (clay and loam) in two combinations (clay over loam...
