The study looked at how water flows over a cylindrical weir in a channel. They used a computer model to simulate the flow and compared it to real-world measurements. The results showed that the flow rate was accurately predicted by the model. They found that the shape of the weir and the water level affect how much water can pass through. The pressure and depth of the water were higher upstream of the weir, while the velocity was higher downstream. The researchers also developed a way to calculate the energy of the flowing water over the weir.
