| Abstract | ||||
| A theoretical model for division of flow through T-junction over a horizontal bed was obtained for subcritical steady flow through main, extension and branch channels of equal widths. The new proposed model was derived with the aid of continuity, energy and momentum equations. For a given inflow discharge, the water depth and the width of the channels, using the present model, the downstream depth and discharge could be determined. Experimental data from previous studies were used to verify the proposed new model. The deduced model was found in good agreement with the observations It was found that a linear relationship has been existed between the experimental data of the inflow water depth with the branch water depth. The equation of trend line was given and it could then be used to compute the branch water depth by knowing the inflow water depth. The energy head-loss coefficient of a junction was approximated and express only in terms of discharge ratio. | ||||
