  "textContent": "A method and system for determining a limit scouring state of riverbed in downstream river channel of a reservoir group are provided. The method includes: collecting discharge data and cross-sectional prototype observation data of the downstream river channel of the reservoir group; establishing a correlation between discharge and a sediment carrying capacity indicator of a cross-section of a controlled hydrological station; calculating variation of the sediment carrying capacity indicator corresponding to dominant discharge; and determining and verifying the limit scouring state of the riverbed in the downstream river channel of the reservoir group. The method determines the limit scouring state of the riverbed in the river channel, and verifies the preliminary screening results based on the cross-section changes with the above determination, so as to provide technical support for mastering the development process of riverbed scouring and scouring trend prediction in the dam downstream river channel of the reservoir group.",
