Constructing of control structures, like dams, change temporal and spatial unequal distribution of water ,and also play an effective role in reduce or eliminate of damage that caused by floods. So reservoir dam’s effect on floods discharges reduction must be determined. In this study the rain Information and flood hydrographs were used to check the flood routing for previous period of Maroon da...

Abstract In the 1940s, Delaware River at Philadelphia was so dirty that pilots could smell it from air. The water harsh corroded metal and discolored paint. Fish killed by pollution washed up on Delaware’s banks. lack of oxygen in parts river blocked critical migration others.

Local scouring in the downstream of hydraulic structures is one of the important issues in river and hydraulic engineering, which involves a lot of costs every year, so the prediction of the rate of scour is important in hydraulic design. Side weirs are the most important of hydraulic structures that are used in passing flow. This study investigate the scouring due to falling jet from side weir...
