A scientific paper entitled (Laboratory study of the submerged flow over the submerged dam, the type of piano key) has been accepted by Professor Dr.
Experimental investigation of submerged flow over piano key weir
In partnership with the student of studies at the College of Engineering, Muhammad Baqir Al-Baghdadi, in the International Journal of Energy and Environmental Foundations (IEEF).
Khassaf explained: The submersible dam is a type of piano key, one of the modern hydraulic facilities, which is used to increase the drainage of excess water from the design storage of the dams. main value of the immersion coefficient. A positional equation has been reached using the dimensional analysis technique and statistical analysis. The equation aims to estimate the value of the decrease coefficient of discharge in the conditions of submerged flow, and it was also found that the coefficient of determination has 0.944
