Obstacle usually blocks the current and it has been found by other researchers an obstacle with a height more than two times of body height of flow is necessary to fully block the density current. The construction of an obstacle with this elevation c

The purpose of this study is to compare the scouring hole geometric dimensions for three kinds of spur-dike: permeable, impermeable and bandal-like for submerged conditions by conducting a set of experimental tests. Bandal-like is made by combining p

Bridges are one of the most important river structures. One of the main causes of bridge failure is local scour at bridge piers. Yearly, Many bridges failed around the world because of disregarding hydraulic factors. Hence, an accurate prediction of

Today, flood management is one of the most important topics in river engineering due to reducing the fatality and damages caused by it. Several hydrodynamic models including 1D, 2D, 3D and couple hydraulic models have been developed in the world. One

Pressure flushing is a common technique to restore the storage capacity of reservoirs. However, the low quantity of flushed sediment remains a drawback of pressure flushing. Experimentally, the present study used inclined plates upstream of the botto

Flood impact assessment in a river system is done with the help of flood routing and this process helps to determine the status of sensitive points of the route in terms of flood entry and the resulting risks for urban and rural areas. For flood rout

The transport of pollutants in the large rivers especially in the lowest downstream reach of a river, in which the velocity and the intensity of flow turbulent become very low, is performed to a great extent by dispersion. Any measure to enhance the

Water and other fluid pipes that are placed on the seabed and rivers bed change the flow pattern around them. These changes increase the shear stress of the bed and the severity of turbulence around the pipe and create a scouring hole under the pipe.
