Influence of approach channel width on flow over thin-plate weir with triangular notch

The bachelor's thesis discussed the determination of the influence of the width of the tributary channel on the overflow through thin-walled spillways with triangular cut-outs with different values of the cut-out angles. The measured data expanded the knowledge in the given area. The expression of the width of the tributary bed is made by introducing the influence of the influence coefficient of the relative width of the tributary bed, and the recommendation is an equation that reflects the influence of the relative width of the tributary bed in a wide range of angle values
