Numerical simulation of A-type hydraulic jumps at positive steps



Numerical simulation of minimum B-jumps at abrupt drops
Tokyay, Nuray; Altan Sakarya, Ayşe Burcu (2008-03-30)
A numerical simulation of minimum B-jumps in horizontal rectangular channels having an abrupt drop is given. Gradually varied, steady, supercritical flow is assumed as the initial condition. An unsteady flow is created by increasing the downstream depth. One-dimensional, unsteady Saint-Venant equations are solved by using the MacCormack and the dissipative two-four explicit finite difference schemes. The steady flow solution is obtained by treating the time variable as an iteration parameter and letting the...
Numerical modeling of shoreline changes around Manavgat river mouth
Al Saleh, Fatıma; Özhan, Erdal; Department of Aerospace Engineering (2004)
River mouths are very active coastal regions. Continuous sediment supply by the river and the movement by wave action cause the shoreline to change in time and space. Modeling of shoreline changes is an essential step before the design of any coastal engineering project. This research aimed to develop a system of numerical models to present the shoreline changes around a river mouth. The system of numerical models has three components: 1) modeling of nearshore wave characteristics, 2) modeling of longshore ...
Experimental investigation of energy dissipation through triangular screens
Güngör, Endam; Bozkuş, Zafer; Department of Civil Engineering (2005)
For the present study, a series of experimental works are executed to dissipate energy through triangular screens. Recent studies have shown that the implementation of the screen for energy dissipation is an effective way to extract out the excessive energy of water downstream of small hydraulic structures located in rivers of relatively negligible sediment content. In the present study, double screen arrangement with a porosity of 40% is used. The inclination angle of the screens is opted as 60 degree. The...
Experimental investigation of energy dissipation through inclined screens
Balkış, Görkem; Bozkuş, Zafer; Department of Civil Engineering (2004)
The main goal of the present study is to investigate the energy dissipation through inclined screens. Recent studies have shown that screens arranged vertically may dissipate more energy than a hydraulic jump does below small hydraulic structures. In the present study a series of laboratory experiments were performed in order to determine the effect of inclination of the screen on the energy dissipated by the screen. The porosity of the screen used in the experiments is 40%. Inclination angle, thickness of ...
Numerical simulation of the Çınarcık dam failure on the Orhaneli River
Bağ, Fırat; Bozkuş, Zafer; Department of Civil Engineering (2005)
This thesis analyzes the probable outcome of the fictitious failure of a dam under a set of pre-defined scenarios, within the framework of a case study, the case subject being the Cinarcik Dam located within Bursa Province of Turkey. The failure of the dam is not analyzed neither structural nor hydraulic-wise but is assumed to be triggered when certain critical criteria are exceeded. Hence, the analyses focus on the aftermath of the failure and strive to anticipate the level of inundation downstream of the ...
