Sharp crested rectangular weirs used for discharge measurement purposes in open channel hydraulics are investigated experimentally. A series of experiments were conducted by measuring discharge and head over the weir for different weir heights for full width weir. It is seen that after a certain weir height, head and discharge relation does not change. Hence a constant weir height is determined. For that height; discharge and head over the weir are measured for variable weir width, starting from the full width weir to slit weir. Description of the discharge coefficient valid for the full range of weir widths and an empirical expression involving dimensionless flow variables is aimed. Experimental data obtained for this purpose and the results of the regression analysis performed are represented.

Numerical modelling of contracted sharp crested weirs / Duru, Aysel; Altan Sakarya, Ayşe Burcu; Kökpınar, M. Ali; Department of Civil Engineering (2014) Sharp crested weirs and gates are flow measurement structures which are frequently used for discharge measurements in channels and laboratories. In this thesis, numerical modelling technique was used in the solution of two flow measurement problems, namely contracted sharp crested weirs (Problem 1) and combined weir and gate system (Problem 2). The numerical simulation of flow cases having similar conditions with the experiments from the previous studies is performed for both Problem 1 and 2. The basic flow...
Experimental analysis of the flow through a bottom outlet on the threshold of motion of particles Göbelez , Özge; Tiğrek, Şahnaz; Department of Civil Engineering (2008) The Shield’s Diagram has been the key stone for the description of initiatial motion of a particle in open channel flow. Data in Shield’s study and further studies are collected in channels. However, the approximation of these data for the case of withdrawal of sediment or clean water through bottom outlets has not been confirmed. Furthermore, two phase models run to simulate the phenomenon so far have used brine and water combination. In this study, an experimental attempt is made to study the behavior of ...
Nonlinear Fiber Modeling of Steel-Concrete Partially Composite Beams with Channel Connectors Ozturk, Alper; Baran, Eray; Tort, Cenk (Springer Science and Business Media LLC, 2019-05-01) A simplified nonlinear fiber-based finite element model of steel-concrete partially composite beams utilizing channel type mechanical shear connectors is developed in OpenSees framework. The interaction between steel beam and concrete slab is accounted for by introducing nonlinear zero length elements and rigid links. The channel shear connector response used in numerical models is based on the previously obtained experimental response from pushout tests. Accuracy of the numerical models in predicting the r...
Measurements of velocity profiles by using particle image velocimeter Kemalli, Onur; Tiğrek, Şahnaz; Department of Civil Engineering (2009) Particle Image Velocimetry (PIV) is an optical technique used to display and evaluate the motion of fine particles in a flow. In this experimental study, velocity profiles are examined by PIV system and basic analysis methods are compared.
Evaluation of cement mortars by ultrasound Paksoy, Nesibe Gözde; Yaman, İsmail Özgür; Department of Civil Engineering (2006) Ultrasonic testing of concrete is often used for the assessment of its uniformity, strength, modulus of elasticity, durability and etc. therefore, the related parameters of testing such as the transducer frequency, the specimen geometry and etc. are well-known. On the other hand, most of the concrete properties are affected by the cement and the mechanical as well as some durability properties of cements are determined through cement mortars. Applications of ultrasound on determining the properties of cemen...
