Hydraulic parameters for the simulated cases.

Cases	Groin; position	(m)		(m)	(m^3/s)	(m)
		U/S	D/S
Case	45°	2	4	0.9	0.043	0.189	0.001	0.01
Case	90°	2	4	0.9	0.043	0.189	0.001	0.01
Case	135°	2	4	0.9	0.043	0.189	0.001	0.01

Here, = length of the straight channel, = width of channel, = upstream discharge, = water depth at downstream, = channel slope, and = Manning’s roughness coefficient.
