The effect of the energy head and the inlet and outlet key width on discharge coefficient of Piano key weir [PDF]

open access: yesفناوری‌های پیشرفته در بهره‌وری آب, 2023
IntroductionPiano key weir is a form of nonlinear weir designed to improve the discharge capacity of spillway structures. Due to the increase in effective length, they can be used in dam spillways or water regulation structures.

Behavior of the Discharge Coefficient for the Overflow Characteristics of Oblique Circular Weirs

open access: yesTikrit Journal of Engineering Sciences, 2012
This paper presents an experimental study and analysis for effect of the geometrical characteristics, of the oblique cylindrical weir on discharge coefficient, wherefrom three sizes used for the weir and two angles for the deviation. From the results, it

Effect of Crest Roughness on Flow Characteristics over Circular Weirs [PDF]

open access: yesCivil Engineering Infrastructures Journal, 2013
Different construction materials with different roughness used to make circular weirs highly affect surface roughness and, in turn, flow hydraulics passing over these structures.

Mapping Tribo-Corrosion Behaviour of TI-6AL-4V Eli in Laboratory Simulated Hip Joint Environments

open access: yesLubricants, 2020
Wear and corrosion in artificial hip replacements are known to result in metal ion release and wear debris induced osteolysis. This may lead to pain and sensitivity for patients.

Experimental Study of Discharge Coefficient at the Dentate Trapezoidal Labyrinth Weir

open access: yesعلوم آب و خاک, 2021
One of the crucial problems that exist in the irrigation networks is the fluctuation of the water surface flow in the main channel and changes in the flow rate of the intake structure.

Experimental study on erosion and sedimentation patterns downstream of a W-weir in a sinusoidal mild bend [PDF]

open access: yes, 2017
Erosion in river bends causes loss of agricultural lands, adjacent facilities, and fish habitat. W-weir structures are recommended for controlling and reducing soil erosion as well as developing habitat for fish and other aquatic organisms.

Use of laser-scan technology to analyse topography and flow in a weir pool [PDF]

open access: yes, 2012
The development of laser-scan techniques provides opportunity for detailed terrain analysis in hydrologic studies. Ground based scans were used to model the ground surface elevation in the area of a stream gauge weir over an area of 240 m<sup>2</

Application of Multi-Criteria Analytic Methods in the Assessment of the Technical Conditions of Small Hydraulic Structures

open access: yesBuildings, 2022
Increasing water demand, combined with unfavourable climate change, creates a need for well-thought-out water management. Such goals are realised thanks to appropriate hydrotechnical infrastructure, the efficiency and functionality of which depend on its
