The effect of crump weir's geometry changes on hydraulic flow characteristics: A review

Abstract

– Water is one of the natural resources that man has known since ancient times and relied on daily. Its availability is an urgent necessity to sustain life and achieve human development. It is the prima food source for many people who live near the river and depend on fishing and agriculture for their livelihood. Therefore, dams are built across rivers to store water and create an artificial lake behind the dam to provide and utilize water and increase the discharge. The current studies focus on one of these types of weirs, the crump weir. Some of these studies deal with adding changes to the geometric shape, such as adding holes with different numbers, changing the height, making the weir in a V-shape, and changing the angle of inclination before and after the weir using artificial intelligence technology. The results showed an increase in the discharge coefficient (Cd) and the flow energy dissipation.
