Mathematical modeling for flood mitigation: Effect of bifurcation angles in river flowrates

This paper investigates the river flowrate at two branches of bifurcated river. The mathematical model fro m the literature is formulated based on momentum principle and mass continuity to cope with river flowrate at different bifurcation angles. The hydraulic variables, geometric properties of trap...
