The researchers studied how water flows over a weir with a bottom opening. They tested different weir heights and opening sizes in a lab flume. They found that adding an opening to the weir changed the flow significantly. They developed equations to calculate the water discharge over the weir with an opening. These equations can help predict how much water will flow over the weir and through the opening.
