Experimental Investigation of Flow Hydraulic in the Branch of rivers (A Case Study: Karkheh River)

open access: yesعلوم آب و خاک, 2019
After Hamidieh Diversion Dam near the city of Hamidieh, Karkheh River is divided into two streams known as Hufel and Nissan. At the lower flow rates, Nissan makes up a greater share than Hufel due to the steeper slope of the former.

Book review: Stumbling over truth: the inside story of the'sexed-up' dossier, Hutton and the BBC [PDF]

open access: yes, 2013
The 2004 Hutton Report ushered in an age of self-doubt and caution at the BBC. It was also the end of the most extraordinary experiment in news management Britain has ever seen: the decade of Alastair Campbell, the Blair courtier who delivered New Labour’

Design and Operational Modifications to Model IV FCCUs to Improve Dynamic Performance [PDF]

open access: yes, 1994
Model IV Fluid Catalytic Cracking Units (FCCUs) differ from other cracking units in that model IV FCCUs do not have slide valves in the catalyst circulation lines to enable direct control of catalyst circulation rate through the unit.

Overflow Characteristic of Cylindrical Shape Crest Weirs over Horizontal Bed

open access: yesTikrit Journal of Engineering Sciences, 2011
The most common types of weirs are the broad-crested weir, the sharp-crested weir, the circular crested weir and the ogee crested weir. Advantages of the cylindrical weir shape include the stable overflow pattern, the ease to pass floating debris, the ...

Dynamics of gabion weirs and its comparison to reinforced concrete weirs

open access: yesKuwait Journal of Science, 2019
Weir is one of the important water divergence structure. Different types of weirs have different hydraulics on upstream as well as downstream resulting in various construction costs and necessary arrangements for safe operation.
