Bottom type water intake structures are frequently preferred in the case of flows containing high levels of sediment in case where it is not possible to construct settling pool or if their construction costs are high. Coanda and Tyrolean type water intake structures are the most commonly used bottom type intake structures. It has been observed in a limited number of studies that Coanda type water intakes are superior to the Tyrolean type water intakes both in terms of withdrawing the design amount of flow and excluding the sediment as much as possible. However, the biggest obstacle to the widespread usage of Coanda type water intake is their complex design and difficulties of the analysis. It has been observed that there are no formula or numerical studies that calculate the water Capture Performance (WCP) and Sediment Release Efficiency (SRE) of the Coanda screens. In order to overcome this gap in the literature, six different Coanda screens have been tested for both WCP and SRE using various incoming flows and sediment compositions. The data obtained as a result of the experimental studies were analyzed using statistical analysis method and two different equations were obtained that enable to find the WCP and SRE. In a situation where the incoming flow conditions and screen parameters are known, someone can gain a preliminary knowledge about the screen performance by using these equations. As a result of this study, adding new data to the literature and eliminating the mentioned lack in the literature was aimed.
