Yellow river China which is plagued by large amount of silts sees an annual operation to move a reported 30 million tons of silt downstream.
Water is discharged at 2,600 cubic meters per second from the Xiaolangdi Reservoir in Luoyang, Henan province, to clear up the sediment in Asia’s second longest river.
The sand-carrying water gushes out of three specialized holes in a 154 meter high, 1,317 meter wide dam lowering the river bed in the lower reach of the river.
The river bed rises each year as some 1.6 million tons of silt deposits build up – sparking fears that this may cause the river to break out its levees during floods.
The speeding currents carry tons of sand into the sea each year.
The highest volume of silt is produced during the rainy season from July to October.
