Water diversion to bifurcating canals has been attracting interest from water engineering researchers for
decades. It can be described by the size of the separation zone in the intake channel and the quantity of
flow rate into the bifurcating channel based on the diversion angle. The present study is an attempt to
determine the optimum diversion angle of bifurcating channels that can achieve the minimum separation
zone size in the intake channel and maximum discharge in the bifurcating channel. The study’s objectives
were achieved by using the theoretical three-dimensional (3D) ANSYS 16 software to investigate the
diverted flow into bifurcating channels with different diversion angles (90, 75, 60, 45, 30, and 15-
degrees). Theoretical expected flow characteristics have been validated by experimental work.
According to the findings, the ANSYS 16 software is a good tool for calculating bifurcating channel flow
patterns. The final results proved that the 15-degree diversion angle has the optimum impact on the
diverted flow. In addition, it achieves a maximum flow rate in the bifurcating channel (about 8.1 L/s),
which represents nearly 49.4% of the main channel flow. It also provides a negligible separation zone with
respect to the other diversion angles of the bifurcating channel. As a result, the efficiency of distributing,
transporting, and controlling the limited amount of water available will improve.
