Özet:Intake structures are defined as structures that divert water into a channel or tunnel leading to a powerhouse. A water intake structure must be able to divert the design discharge into the conveyance system with minimum head loss and negative impact on the local environment. Design and location of intakes are dependent on geological, hydraulic, structural and economic conditions. Tyrolean type water-intake structures are commonly constructed on steeply sloped mountain rivers with reliable rock foundation to divert water. The amount of water to be diverted from the main channel is the major concern in these kind of structures. Incoming flow must satisfy the design discharge for an appropriate design. There are various parameters affecting the amount of diverted water and the present work does not fully clarify hydraulics of this structure. In this study, design methods of Tyrolean type water intake structures are researched. The researches are made in two perspectives named as constant energy level and constant energy head hypothesis. In the first stage of this study, the theoretical methods related to the design of Tyrolean weirs are presented. In the second stage experimental solutions obtained as a result of hydraulic studies are discussed. In the third stage outcome of the theoretical methods vi are compared with the experimental methods. It was shown that the Tyrolean weir designed with the method based on experimental results provides more diverted discharge from the main channel with a trash rack of shorter length than those of the other methods. Finally, the situations of some of the currently operating facilities are examined.
