Hydroelectric dams build on the rivers block most of the flow section and leaves no space for the migrating fish along the rivers. Fish passages are built along the river at those locations to overcome this problem. Understanding the hydrodynamics inside these structures is essential in the design process. Parameters like discharge, velocity, acceleration and turbulence inside the fish passage can be obtained using three dimensional numerical simulations. Change in these parameters is investigated for different fish passage designs within this study. Overall, computational fluid dynamics (CFD) appears to be an effective tool for analyzing free surface flows over technical fish passes for studying of different design scenarios.

Numerical modelling of free surface flows on round vertical slot fish passes Koçal, Çiğdem; Köken, Mete; Department of Civil Engineering (2019) Dams and weirs built on the rivers block the flow and prevent fishes from migrating along the river. To overcome this problem, fish passes can be built at those blocked locations along the river by providing a gently sloped channel with low flow rates and enough water depth to allow fish to ascend. Considering the design process, understanding the hydrodynamics inside fish pass structures is important. By using three dimensional numerical simulations, parameters like flow rates, velocity, turbulence and wat...
Determination of optimum rack angle of tyrolean type water-intake structures Melek, Abiddin Berhan; Göğüş, Mustafa; Department of Civil Engineering (2017) Tyrolean weir is known as an effective device to separate major part of sediment from the main channel flow in order to provide required sediment-free water discharge for run-off river hydropower plants. Basically, in the design of Tyrolean weirs, the main concern is to divert at least the design discharge of the facility while it permits to enter the minimum amount of bed-sediment to the system. In this study, water and sediment capture rates of Tyrolean type water-intake structures were investigated for a...
Hydraulic characteristics of tyrolean weirs having steel racks and circular-perforated entry Şahiner, Halit; Göğüş, Mustafa; Department of Civil Engineering (2012) Tyrolean type water-intake structures are commonly used on mountain rivers to supply water to hydropower stations. The amount of water to be diverted from the main channel is the major concern in these kind of structures and should not be less than the design discharge. In this study a physical model of a Tyrolean type water-intake structure was built at the laboratory and the diverted flow from the main channel through the intake structure having steel racks and perforated plates of different types were me...
Experimental Investigation of Flow Conditions over Cambasi Dam Spillway Altan Sakarya, Ayşe Burcu; Aydın, İsmail; Göğüş, Mustafa; Köken, Mete (2013-09-13) The entrance conditions, flow around the piers and the pressure distributions along the centerline and the side of the spillway channel for different discharges were investigated for Cambasi dam that will be constructed at the intersection of Kabali and Hamzabey rivers in Ordu District. Hydraulic model of the spillway was constructed at a length scale of 1/20, based on the Froude similarity. Additionally, the water depths and the velocities through the channel sections at different locations were investigat...
Numerical investigation of hydraulic characteristics of Laleli Dam spillway and comparison with physical model study Usta, Eray; Köken, Mete; Department of Civil Engineering (2014) Spillway is a hydraulic structure that is used to pass big discharges in flood times in a controlled manner and release surplus water that cannot be safely stored in the reservoir to downstream. During the design process of the spillways, determining of hydraulic behavior of these structures is a very significant issue for an accurate and optimum design. In this thesis, the objective is to investigate the hydraulic characteristics of the flow over Laleli dam spillway numerically and compare the results with...
