It is also called normal weight concrete or normal strength concrete.

Hydropower planning covers a wide range of topics. Professionals from many disciplines take part in the planning and implementation of hydropower projects.

Hydraulic jump is the phenomenon of open channels. Before defining the hydraulic jump it is necessary to describe the terms "super critical flow" and "sub critical flow" in order to clearly understand that "what is hydraulic jump" Hydraulic jump usually occurs in super critical flow. In order to describe the super critical flow and sub critical flow, there is need to define the

Hydraulic jumps are very efficient in dissipating the energy of the flow to make it more controllable & les erosive. In engineering practice, the hydraulic jump frequently appears downstream from

Concrete has a very low tensile strength and requires the use of reinforcing bars at tensile zone. Forms are required to hold the concrete in place until it hardens sufficiently. The low strength per unit of weight of concrete leads to heavy members and is an important consideration for tall buildings and long-span structures. The properties of concrete
