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...

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.

An example of river bifurcation problem is given by UTM Centre for Industrial and Applied Mathematics (UTM-CIAM), Universiti Teknologi Malaysia. Maple software is used to implement the proposed model equation and generate the results. The amount of bifurcated river flowrate with different bifurcation angles is determined, resulting in a reasonable discussion.
