Tyrolean type water-intake structures are commonly constructed on steeply sloped mountain rivers to divert water with the minimum amount of sediment. There are various parameters affecting the amount of diverted water and sediment among which the most important ones are the length and inclination angle of the rack, and the distance between the rack bars. In this study, on a Tyrolean type intake model constructed in a channel 7 m long and 1.98 m wide at the laboratory, a series of experiments were conducted with water and sediment of various gradations. Three different racks having various bar spacing; 3mm, 6 mm and 10 mm were tested at the rack angles of θ=19° and θ=23° and the sediment capture capacities of each rack were determined. The results of the experiments were compared with the previously obtained results, and the effect of rack inclination on the sediment capture efficiency of the system was determined.
