Abstract
The
main-channel of the lower Yellow River is the main path for flood and sediment
transportation, and the flow is the key factor to keep its bank-full discharge
at an acceptable level. After Xiaolangdi Reservoir
become effective, the sediment will be transported mainly during flood season.
Based on the analysis about the future sediment load and flood situation,
sediment carrying capacity of floods in different magnitude, and the relation
between floods in different magnitude and main-channel cross-section, the paper
has demonstrated the flood volume needed for keeping the main-channel’s
bank-full discharge at around
