Abstract

Multi-object application and water and sediment regulation of the Xiaolangdi Reservoir since 2001 have changed the flow and sediment conditions entering the Lower Reaches of Yellow River and the Estuary. Field flow and sediment data at Lijin Hydrological Station and river cross section elevation data downstream from Lijin Section during 2001~2010 have shown that the Estuary have been in a state of little scouring. The 2D mathematical model has been used to study the flow and sediment conditions for the Yellow River Estuary balance. The conclusions have arrived at that total annual water volume is 196 × 108 m3, total annual sediment volume is 1.40~1.70×108 t, coarse sediment concentration is 3kg/m3.
