Open channel flows play a significant role within major metropolitan areas in the removal of excess surface runoff. Main channels are responsible for the removal of all excess surface runoff which are fed by connecting tributaries. Both main channels and tributaries can occur naturally or be manmade but their orientation must be considered in the removal of excess surface run off. It is believed that the angle in which the tributaries connect to the main channel is an important factor in whether the run off is removed efficiently or a major contributor to flooding. Current practice requires tributaries in flood control channels to enter at small angles to avoid disrupting flow in the main channel and impacting channel capacity. These small angles are costly to construct and their value is questionable, especially when tributary flow is small compared to the main channel capacity. This is often the case, especially for smaller tributaries and conduits. There is a need to evaluate the impact of tributary discharges into open channels across a range of flow rates, velocities, and entrance angles.
