[0054] Please referring to FIG. 1, the disclosure discloses a method for determining a limit scouring state of a riverbed in a downstream river channel of a reservoir group, which includes the following steps 1-4.

[0055] In step 1, discharge data and cross-sectional prototype observation data of the downstream river channel of the reservoir group are collected, which is achieved by the following steps 11-12.

[0056] In step 11, measured discharge data and cross-sectional data of a controlled hydrological station in the downstream river channel of the reservoir group are collected, and measured velocity and water depth data are organized.

[0057] In step 12, a cross-sectional change diagram of the controlled hydrological station is superimposed according to the cross-sectional data, a discharge area and an average riverbed elevation under a bankfull stage are calculated according to the measured discharge data, the measured discharge velocity data and the water depth data, time-varying hydrographs of the discharge area and the average riverbed elevation under the bankfull stage are drawn, and a scouring state of the cross-section and a near-stable time of the scouring state of the cross-section are preliminarily analyzed.

[0058] In step 2, a correlation between discharge of a cross-section of a controlled hydrological station and a sediment carrying capacity indicator of the cross-section of the controlled hydrological station is established, which is achieved through the following steps 21-23.

[0059] In step 21, the sediment carrying capacity indicator U.sup.3/h of the cross-section of the controlled hydrological station is calculated, the correlation between the discharge the cross-section of the controlled hydrological station and the sediment carrying capacity indicator at a control cross-section is established, and a correlation curve diagram of QU.sup.3/h is drawn. U represents an average flow velocity at the cross-section, in m/s, h represents an average water depth at the cross-sectional, with a unit of m, and Q represents the discharge at the cross-sectional with a unit of m.sup.3/s.

[0060] In step 22, a curve diagram of QQ.sup.mJP of the controlled hydrological station is drawn by using a Makaveev method, where m represents a sediment transport coefficient, J represents a bed slope, P represents discharge frequency, and m, J and P are dimensionless parameters; and Q JP comprehensively represents a sediment transport capacity of water flow. A dominant discharge of the downstream river channel of a dam is calculated after storage and operation of the reservoir group.

[0061] In step 23, sediment carrying capacity indicators corresponding to the dominant discharge is identified year by year based on the correlation curve diagram of QU.sup.3/h to obtain annual values of the sediment carrying capacity indicators.

[0062] In step 3, variation of the sediment carrying capacity indicator corresponding to the dominant discharge is calculated, which is achieved through the following steps 31-33.

[0063] In step 31, a 10-year period with a strong channel formation effect is selected according to a duration of the dominant discharge, to calculate a time period average value of the sediment carrying capacity indicators corresponding to the dominant discharge.

[0064] In step 32, 5-year moving average values of the sediment carrying capacity indicators corresponding to the dominant discharge are calculated according to a hysteresis response principle of riverbed scouring and silting adjustment.

[0065] In step 33, curves of the annual values, the 5-year moving average values and the time period average value of the sediment carrying capacity indicators corresponding to the dominant discharge are drawn.

[0066] In step 4, the limit scouring state of the riverbed in the downstream river channel of the reservoir group is determined and verified, which is achieved through the following steps 41-43.

[0067] In step 41, the curves obtained in step 33 are analyzed. In response to the curves of the annual values, the 5-year moving average values and the time period average value of the sediment carrying capacity indicators corresponding to the dominant discharge beginning to coincide at a coincided point, it indicates that a riverbed of a reach where the controlled hydrological station is located enters the limit scouring state from a time point of the coincided point. In response to the curves of the annual values, the 5-year moving average values and the time period average value of the sediment carrying capacity indicators corresponding to the dominant discharge not coinciding, it indicates that scouring at the reach where the controlled hydrological station is located continue to develop and has not yet entered the limit scouring state.

[0068] In step 42, the near-stable time in the step 12 and the time point in the step 41 are compared, when the near-stable time and the time point are close, it further indicates that the riverbed enters the limit scouring state.

[0069] In step 43, a duration for the downstream river channel of the reservoir group to reach the limit scouring state is obtained.

[0070] The specific steps of the embodiment are as follows.

[0071] In step 1, observation data of about 20 years from 2002 to 2022 such as measured discharge data, daily average discharge data, bed slope data, and large cross-section data of two controlled hydrological stations within 150 kilometers (km) of downstream of a reservoir group in a certain basin is collected. The cross-sectional change diagrams of the two controlled hydrological stations are superimposed as shown in FIGS. 2A and 2B. A discharge area and an average riverbed elevation under a bankfull stage are calculated, time-varying hydrographs of the discharge area and the average riverbed elevation under the bankfull stage are drawn as shown in FIGS. 3A and 3B. A scouring state of the cross-section and a near-stable time of the scouring state of the cross-section are preliminarily analyzed. Specifically, the large cross-section of the ZC hydrological station remained stable in shape from 2016 to 2022, the change rates of the discharge area and the average riverbed elevation of the cross-section under the bankfull stage have slowed down significantly after 2014. It is preliminarily determined that a riverbed of a reach where the ZC hydrological station is located has entered the limit scouring state since 2014. The changes in the SS hydrological station are different from that of the ZC hydrological station. From 2002 to 2022, the cross-section has always been in a state of scouring adjustment. The change rates of the discharge area and the average riverbed elevation of the cross-section under the bankfull stage show a process of first increasing, then decreasing, and then increasing. It is preliminarily determined that a riverbed of a reach where the SS hydrological station is located has not yet entered the limit scouring state.

[0072] In step 2, the sediment carrying capacity indicators U.sup.3/h of the cross-sections on the ZC hydrological station and the SS hydrological station are calculated based on the measured discharge data from 2003 to 2022, and change curves (i.e., the correlation curve diagram of QU.sup.3/h) of the sediment carrying capacity indicators U.sup.3/h with the discharge Q are drawn as shown in FIGS. 4A and 4B. The curve diagrams of QQ.sup.mJP of the ZC hydrological station and the SS hydrological station from 2003 to 2022 after the operation of the reservoir group are calculated and drawn using the average daily discharge and the bed slopes of the stations based on the Makaveev method, and the curve diagrams of QQ.sup.mJP are shown in FIGS. 5A and 5B. The corresponding dominant discharges are 28000 m.sup.3/s and 23000 m.sup.3/s, respectively. The sediment carrying capacity indicators corresponding to the dominant discharges of the two hydrological stations are identified year by year comparing the correlation shown in FIGS. 4A and 4B.

[0073] In step 3, durations of the inflow flow exceeding the dominant discharge at the ZC hydrological station and the SS hydrological station year by year are counted, a 10-year moving average values of the durations are calculated, and 10-year hydrological series with a longer duration of dominant discharge and a strong channel formation effect are screened out as 2013-2022. A time period average value of the sediment-carrying capacity indicators corresponding to the dominant discharge for each hydrological station from 2013 to 2022 is calculated. 5-year moving average values of the sediment carrying capacity indicators corresponding to the dominant discharge are calculated according to the hysteresis response principle of riverbed scouring and silting adjustment. Curves of annual values, the 5-year moving average values and 10-year average values (i.e., the time period average value) with strong channel formation effect of the sediment carrying capacity indicators corresponding to the dominant discharge are drawn as shown in FIGS. 6A and 6B.

[0074] In step 4, the curves in FIGS. 6A and 6B are analyzed. Since 2014, the curves of the annual values, the 5-year moving average values and the time period average value of the sediment carrying capacity indicators corresponding to the dominant discharge of the ZC hydrological station begin to coincide at a coincided point, it indicates that the riverbed of the reach where the ZC hydrological station is located has entered the limit scouring state from a time point of the coincided point. The curves of the sediment carrying capacity indicators of the dominant discharge of the SS hydrological station do not coincide, it indicates that the scouring of the reach where the SS hydrological station is located will continue to develop and has not yet entered the limit scouring state. The near-stable time in the step 12 and the time point in the step 41 are compared, the time obtained by both for the scouring of the ZC hydrological station to the limit state is 2014, further indicating that the riverbed in the reach where the station is located has entered the limit scouring state, and the duration for the riverbed to reach the limit scouring state is 11 years. The riverbed of the river reach where the SS hydrological station is located has not yet entered the limit scouring state, and the scouring will continue to develop.
